Historical Perspectives on Biological EM
Biological EM began in 1934. The first challenge was radiation damage, but after fixation was established, production of thin samples became the central problem. As specimen preparation evolved, the challenge of radiation damage returned, and can now be dealt with. For decades, resolution was limited by metallic stains, but now near-atomic resolution is reached with unfixed, unstained specimens. Some of the key events and persons in the technical development of biological TEM will be described.

Additional Topics:

Some Basics of Confocal Imaging: How Deep is Deep and are They Really Colocalized?
Questions asked by operators of confocal microscopes often include how deep can I image into a tissue, are the labeled structures co-localized, and can I quantify the fluorescence in the image? This presentation will discuss the role of optics, selection of appropriate fluorochromes, and the proper set up of imaging parameters on a confocal microscope to correctly address these types of common questions.

Bob Price received his graduate degrees from Southern Illinois University and has directed core imaging facilities at Southern Illinois University, Case Western Reserve University and The University of South Carolina School of Medicine. He has participated in and led a number of confocal microscopy workshops and with Dr. Jay Jerome co-authored “Basic Confocal Microscopy” which is a leading text on the use of confocal microscopes. He served as Program Chair for the Microscopy and Microanalysis meetings in 2001 and 2005 and as Editor-in-Chief of the journal Microscopy and Microanalysis for 8 years. He has previously been awarded the MSA Mort Maser Distinguished Service Award, is a Fellow of MSA, and is currently President-Elect of MSA.

3-D and In-situ Characterization of Nanomaterials in the Scanning Transmission Electron Microscope
All nanomaterials are three-dimensional (3-D) in nature whether they are used for catalysis, energy storage, semiconductors, or medicine. While (scanning) transmission electron microscopes ((S)TEMs) are typically used to analyze these materials, the images are 2-D projections of 3-D objects. In order to understand the true nature of the nanomaterial, a 3-D tomogram is necessary on the nano- or atomic scale. Traditionally, this involves taking a series of images of the sample at different tilt angles, normally ranging between -70º to +70º every 1 to 2 degrees, and using these two dimensional images to reconstruct a three dimensional volume of the sample. This tilt range may increase depending on the sample geometry and the holder used, but there is a constant battle against an artifact in the reconstruction called the missing wedge. This effect may be reduced greatly by performing dual axis tomography, or overcome completely using new holder technologies, but each technique has its pros and cons. Another approach that has been taken in the last 3-5 years is the development of novel algorithms that greatly reduce the effects of the missing wedge and even provide atomic resolution 3-D tomograms from just a few projection images.

With recent advances in in-situ microscopy, a new era in microscopy has arrived that allows for the dynamic imaging of materials under reaction conditions. It is no longer sufficient to image materials in vacuum conditions, but to get closer to the conditions in which the material will be used, such as high temperature, liquid environments, gas environments or a combination thereof. Combining an in-situ or ex-situ experiment with STEM tomography is a very powerful method for materials characterization. The benefits and limitations of all these methods will be discussed through examples of different inorganic materials.

The Future of TEM and why we must Remember the Past
The subject of this talk concerns the future of TEM. TEM is facing many challenges including the fact that the top-of-the-line microscopes are becoming more expensive and more complex even when they seem simpler because of the increasing use of computers and a clear affordable textbook. The techniques used by the different communities (physical sciences and life sciences) are also often converging especially for those specializing in 3D imaging, spectral imaging, low-dose imaging (we all should be) and aberration-corrected imaging. (Who is specializing in non-aberration-corrected imaging?)

I'll illustrate the talk with some examples of work from my group and from friends. My field of research is Ceramic Materials so I'll use my crystal ball to suggest some potential directions that TEM as a whole might follow in the next few years, and in so doing explain the title.

Experiments in the TEM
If we define an experiment in the TEM as changing the specimen while we observe it, we are always doing such experiments! The next questions are do we know what we are doing (to change the specimen) and can we make measurements. In this talk I will examine the past, present and future of in-situ experimentation in the TEM, what are the challenges in doing the experiments and interpreting the results, and how we are interfacing to other instruments to make the TEM a real operando instrument. I will, of course, mention the Companion Volume to that clear affordable textbook and even use some Ceramic Materials to illustrate the talk!

FIB Development and Applications Through the Years
Focused ion beam (FIB) microscopy, specimen preparation, and nanoprototyping has witnessed numerous advances over the past 20+ years. First perceived as an expensive novelty, the FIB currently offers necessary and indispensable capabilities for any major research university, company, or national laboratory. FIB usage for site specific milling and deposition is now status quo. Standard specimen preparation protocol exists for high resolution transmission electron microscopy and other characterization analyses requiring minimal surface damage. Over the years, these techniques improved with an understanding and application of the fundamentals of ion-solid interactions. Successive FIB slicing followed by imaging and associated analytical methods enable 3D tomographic materials characterization containing morphology, microstructure, chemistry, and crystallography. The automation of these functions improves reliability, statistics, and throughput. Despite its maturity, FIB instrumentation and applications continue to develop. New sources emitting different ions species and beam currents allow materials characterization across the nano-, micro-, and macro- length scales. In addition, easier and faster micromanipulation methods performed outside the FIB optimize FIB instrumentation usage. In this lecture, FIB development and applications characterization and prototyping will be presented. Attention will be given to discoveries of structure/property relationships in materials possible only by FIB. In addition, the future of FIB will be discussed. Examples from metals, ceramics, polymers, composites, integrated circuits, minerals, biomaterials, and nuclear irradiated materials will be provided.

Lucille A. Giannuzzi holds a B.E. in Engineering Science and M.S. in Materials Science and Engineering from Stony Brook University. She received her Ph.D. from Penn State in Metals Science and Engineering and was a Post-Doc at the PSU Center for Advanced Materials.

Jay Jerome      MSA President 2006

The Role of Microscopy in Atherosclerosis (Hardening of the Arteries) Research
Microscopy has been critical to research in cardiovascular disease. This talk, aimed at the educated lay audience, reviews our current understanding of the causes of hardening of the arteries with particular emphasis on how microscopy has contributed to this understanding.

Quantitation of Biological Structure
A discussion of the various schemes for gaining quantitative structural information microscopically from biological samples using my own work as practical examples and how to avoid some common mistakes I have run across over the years.

Basic Digital Imaging and Image Formats
Most microscopy is now digital image based yet many microscopists do not fully understand basic digital image concepts. This talk covers, in a general, easy to follow manner, the basics of digital imaging in order to provide the microscopist with sufficient information to avoid common pitfalls. The field of "scientific" digital imaging is only a small subset of digital imaging. There are lots of things you can do in digital imaging that you should not do in scientific imaging because it destroys the integrity of your data; the image. Unfortunately, with modern digital imaging it is far too easy to inadvertently alter the image without even knowing that you have done so. In this talk, we review the basics of a digital image and discuss how to match the microscope parameters and image capture parameters in order to maximize image fidelity. We will also discuss post image processing and how these can affect the image data. Finally, the basics of image formats (JPEG, TIFF) are critical but not always understood, so we include a discussion of the appropriate uses of these formats. The image information is the data and not understanding basic "scientific" digital imaging can lead to accumulation of artefactual errors.

Jay Jerome is Director of Graduate Studies for the Molecular Pathogenesis and Immunology Program at Vanderbilt University Medical Center, and co-director of the Cell Imaging Shared Resource, Vanderbilt University Shared Resource for High-end Light and Electron Microscopy. He has authored over 100 manuscripts, most using some form of microscopy.

The mechanism of mineral formation in vertebrates
Mineralization in vertebrates occurs normally in bone, calcifying cartilage and tendon, and dentin, cementum and enamel of the teeth. The process is considered to involve interactions of inorganic calcium and phosphate ions with organic components (proteins) synthesized and secreted to extracellular matrices by specialized cells of these various tissues. The principal organic constituent regulating mineral formation of all vertebrate tissues except enamel is collagen. A small, non-collagenous protein, osteocalcin, has very recently been suggested to have a role with collagen in vertebrate mineralization. The organic constituents of enamel mediating mineralization are amelogenin and possibly other proteins. Light microscopy and transmission electron microscopy, including immunocytochemistry, high voltage microscopy and three-dimensional tomography, will describe the mechanism by which normal mineral formation is thought to occur in association with collagen, osteocalcin and amelogenin in the appropriate vertebrate tissues above. Reference to pathological mineralization, in muscle, skin, and other tissues, will also be made.

Tissue engineering of models of human digits and ears
Tissue engineering is a relatively recent and potentially powerful means of augmenting, repairing, and replacing various tissues that may be congenitally defective, injured, diseased, damaged or otherwise impaired in the human body. The approach of tissue engineering commonly involves seeding isolates of specific cells onto a biodegradable polymer scaffold to form a cell/scaffold construct. The construct is subsequently developed in vitro or in situ for ultimate use as a possible replacement tissue. Bone and cartilage structures, such as a human digit or ear, have now been modeled by tissue engineering methods. The presentation will describe by light and electron microscopy, correlated with laser capture microdissection and gene expression, the tissue engineering of current models of human phalanges and ears. Compared to bone and cartilage in vivo, these models demonstrate several similarities in structure, composition, and response to mechanical forces and they suggest great promise for further advances in their clinical applications.

Rapid Specimen Preparation Methods for Biological Electron Microscopy of Resin-embedded Samples
While many labs are moving toward cryo-methods for preparing biological samples for EM, the great majority of work involving sections of resin-embedded materials is still done by methods that are fundamentally unchanged from the 1960's. Consequently, the preservation of cell ultrastructure is compromised by the artifacts that result from this type of processing. In this presentation we will show how using cryofixation and low temperature dehydration we can greatly reduce the total processing time to a few hours, while producing results that have far fewer distortions compared to conventional preparation methods. High pressure freezing of living material is the preferred starting point, but we will discuss alternatives for samples that do not lend themselves to that approach. Dehydration and chemical stabilization of cell structure can be done by freeze substitution over a period of 3 hours or so, followed by infiltration with resin and subsequent polymerization in another 3 hours. Rapid methods can also apply to samples destined for on-section immunolabeling in either Lowicryl, or LR resins. Correlative light and electron microscopy techniques for preserving fluorescence in polymerized resin will also be discussed.

Kent McDonald received his Ph.D. in Botany from the University of California, Berkeley in 1972. Following a year teaching at UCLA, he took a Post-doctoral position at the University of Colorado, Boulder. In 1975, he re-focus his research on the cell biology of mitosis which led him back to Berkeley in 1979 to work on correlative light and electron microscopy of PtK cells and diatoms. In 1987 he returned to Boulder to join the High Voltage EM Lab and at this time realized the importance of cryofixation by high pressure. In 1993 he moved back to Berkeley to assume the Directorship of the campus Electron Microscope Laboratory. His current research interest is improving the instrumentation for correlative light and electron microscopy using high pressure freezing and tomographic 3-D imaging.

Emerging Diseases and Microscopy
Infectious diseases are the leading cause of death worldwide and the third leading cause in the US; many can be classified as emerging diseases. Some may be caused by truly novel pathogens, in other cases, the causative organisms have been present for many years, but have escaped detection until recently. Still others represent the re-emergence of known pathogenic organisms after a long period of quiescence. The mention of emerging pathogens brings to mind sensational, exotic and feared microorganisms such as Ebola virus, human immunodeficiency virus (HIV), hantavirus, West Nile virus, Yersinia pestis (plague), and prion diseases such as bovine spongiform encephalitis (BSE, mad cow disease) which have been associated with variant Creutzfeldt-Jakob disease (CJD) in humans. However, other organisms that have been known for some time can be classified as emerging pathogens as they continually mutate, recombine, and adapt, like influenzavirus, causing misery and death. A major category of emerging diseases is that of drug-resistant organisms. Changes in technology permit organism spread by contaminated water and air conditioning systems, by surgical and diagnostic instruments, or by transplantation. Geographic spread of disease organisms through more widespread human travel, transport of vectors in shipping containers, and increased mobility of insects and animals accounts for some emerging diseases. Food-borne illnesses are a world wide problem. In addition to agents that actually invade and cause disease, numerous organisms cause tremendous morbidity and some mortality through toxin production. Increased awareness due to better detection and identification methods has brought these organisms to the forefront. Microscopy techniques for detection of organisms are rapid and do not require specific probes. Electron microscopy is particularly useful for viral agents. It can visualize a wide variety of viruses at once, including non-cultivable and unexpected ones. It does not require antibodies or nucleic acid reagents for identification, and it is rapid; negative staining of fluid samples can be accomplished in a matter of minutes to a couple of hours. Thin sectioning of cells can be accomplished in one to two days. Finally, speed of microscopical methods and lack of requirements for probes are the reasons microscopy laboratories are being asked to participate in the surveillance for bioterrorism agents-horrible and feared examples of emerging diseases.

Imaging the Molecular Mechanisms of Glucose-Stimulated Insulin Secretion
The islet of Langerhans is the functional unit responsible for glucose-regulate secretion of insulin and glucagon, and thus plays a key role in blood glucose homeostasis. Over the last 25 years, we have been interested in understanding the multicellular mechanisms of islet function, and their role in the regulation of blood glucose under normal and pathological conditions. Using our unique quantitative optical imaging methods and novel microfluidic devices, the dynamics of these molecular mechanisms can be followed quantitatively in living cells within intact islets.

Many of these experiments require hyperspectral imaging and live-cell Förster resonance energy transfer (FRET) with differently colored fluorescent proteins. We have exploited spectral confocal microscopy for quantitative multi-color imaging as well as FRET. Current spectral imaging devices are limited by a trade-off problem between image acquisition rate and signal throughput and dynamic range. To overcome this problem, we have used a snapshot hyperspectral imager — Image Mapping Spectrometer (IMS). The IMS utilizes an image mapper to remap a sample's x,y,λ datacube to a 2D detector array for parallel measurement. Since no scanning is employed, the whole datacube can be captured in a single snapshot, and optical throughput is maximized. FRET measurements can also be facilitated using photoswitchable FPs to achieve a lock-in type detection. This allows FRET to detect the interactions of a few fluorophores even in a sea of non-interacting molecules.

As an alternative to FRET, we have leveraged two-color Fluorescence Fluctuation Spectroscopy (FFS), which can be used to directly measure diffusion and binding rates of proteins within the cell. Using FFS to measure protein binding and diffusion allows quantification at the molecular level of protein interactions, and also overcomes many of the difficulties found in FRET imaging experiments. FFS can also provide information on protein molecular concentrations. Quantifying the molecular concentrations and interactions within islet cell pathways illuminates signaling mechanisms, and thus provides essential information for developing therapeutic treatments for patients with diabetes.

Many aspects of these studies can be covered in a single lecture with a focus on imaging technology, quantitative data analysis, or biomedical applications.

David W. Piston is the Edward J. Mallinckrodt Jr. Professor and Head of the Department of Cell Biology & Physiology at Washington University in St. Louis. Dr. Piston was trained in physics at the University of Illinois, completed a postdoctoral research fellowship in applied physics at Cornell University, and joined the faculty at Vanderbilt University in 1992 where he remained until 2014. He served as President of the Microscopy Society of America in 2010, and has been recognized as a Beckman Young Investigator Award (1993), NIH Study Section Chair (2004-2006), Searle Scholars Advisory Board (2006-20112) and election as a Fellow of the American Physical Society (2000), the Microscopy Society of America (2014), and the American Association for the Advancement of Science (2016). His research group focuses on the understanding the molecular mechanisms that underlie hormone secretion from islets of Langerhans in the pancreas. Driven by this biomedical focus, the lab develops, optimizes, and applies novel fluorescence microscopies and probes, largely based on the Green Fluorescent Protein and its relatives.

Fungi in the Human Environment
Fungi are fundamentally recyclers. Their main function in the environment is to break down complex materials, which allows the components to be re-used by other organisms. These complex materials include dead plants, dead animals, building materials, valued artifacts of civilization and any number of other things. Problems arise when these organisms invade the built environment, either work or living spaces. Various methods, such as air sampling, have been commonly used to estimate the density of fungi in a structure. Volumetric sampling may indicate high levels of fungi or one particular fungus in a building compared to the outdoor environment or some predetermined standard. This method may indicate the presence of viable fungal conidia or hyphal fragments in the air column but it cannot identify sites of colonization. Surface cultures may indicate the presence of viable fungal propagules but do not prove colonization. Surface sampling for light microscopy using clear adhesive tape mounts may demonstrate the presence of colonizing fungi. The methodology, such as types of tape and optics employed may affect the results obtained. Examination of tape samples from environmental surfaces may show the level of colonization and, in many cases, allow for identification of colonizing species. Scanning electron microscopy studies of suspect materials may determine the nature of surface features and contamination not readily identifiable in the light microscope. Suspect materials may be shown to be biological in nature or non-biological surface. Microanalysis of materials may yield clues to the origin of non-biological contamination. Rapid and accurate analysis of suspect materials on indoor surfaces is vital to the identification of potential fungal colonization sites. These data may be used as an aid to determining an appropriate course of action.

Microbial Ecology of Extreme Environments: Automobile Air Conditioning Systems
Automobile air conditioning systems might be considered an extreme environment for many microorganisms. Organisms surviving and proliferating in these systems may be presented with temperature changes ranging from sub-zero to over 140°F, water activity from saturation to dryness and a nutrient complexity including varying levels of hydrocarbons. Microbial communities may develop in these systems and sometimes proliferate to the extent of massive colonization and production of objectionable odors. In a few instances microorganisms emanating from ACS have been associated with hypersensitivity pneumonitis and other allergic reactions. We have demonstrated that foam insulation and glues, in particular, on system insulations may be colonized by fungi such as Aspergillus, Aureobasidium, Cladosporium, and Penicillium. Such fungi often are implicated in colonization of similar substrates in buildings categorized with the sick building syndrome. Combined light microscopy, scanning and transmission electron microscopy and culture techniques have provided profiles of the microbial communities which inhabit some automobile air conditioning systems.

Microscopy into Art: Adaptive Interpretation
Beautiful images captured through microscopes are often considered works of art in themselves. Artists have been taking these images as inspiration for creative adventures using media other than photography to convey the complex and often breathtaking sights previously seen by only a select few. In the hands of artist such as Salvador Dali, Fuco Verdura and Luke Jerram the (mostly) unseen world comes alive through the use of glass, paper, paint and other media bringing microscopic worlds to light. The ever-present influence of microscopy on the art world is enlightening, inspiring and often quite surprising.
