Book excerpt: Expansion microscopy (ExM) enables 3-D, nanoscale-precise imaging of biological specimens by isotropic swelling of hydrogel-embedded, chemically processed tissue. Such capability raises the question of whether nanoscale mapping of biomolecules could be performed in an entire organism, which would allow super-resolution-mediated in situ analyses, such as digital quantification of biomolecules and mapping of synaptic contacts, to be performed within the context of an entire nervous system. The nematode Caenorhabditis elegans could be a suitable model for such organism-wide analyses, due to its tractable physical size, deterministic cell lineage, ease of genetic control, and well-established literature. However, C. elegans is enclosed in a chemically impermeable and mechanically tough cuticle, which could hinder the deployment of ExM. In this thesis, we present a strategy, expansion of C. elegans (ExCel), to expand fixed, cuticle-enclosed intact animals of C. elegans. ExCel enables simultaneous readout of fluorescent proteins, RNAs, DNA locations, and anatomical structures at resolutions of ~65-75 nm (3.3-3.8x linear expansion). We also developed epitope-preserving ExCel, which enables imaging of endogenous proteins stained by antibodies, and iterative ExCel, which enables imaging of fluorescent proteins at a ~25-nm resolution (20x linear expansion). We demonstrate the utility of the ExCel toolbox for multiplexed imaging of multiple molecular types, for mapping synaptic proteins, for identifying previously unreported proteins at cell junctions, and for gene expression analysis in multiple individual neurons of the same animal. In addition to ExCel, we discuss two other ExM-related technologies, including tetragel, which is a highly homogeneous hydrogel network that improves the nanoscale isotropy of biological ultrastructure expanded by ExM, and stochastic arrangement of reporters in clusters (STARC), which is a strategy for recording neuronal activity at a subneurite-level resolution, in densely labeled neuronal populations. Taken together, the work presented in this thesis extends the capabilities of ExM, and lays the foundation for a comprehensive, functionally and structurally informed analysis of an entire organism, which could reveal new insights in neuroscience, organismal development, and systems biology.

This book was released on 2021 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: The abbreviated cell cycle is a poorly understood form of the cell cycle essential for genome stability in stem cells. To visualize cell-cycle events in the abbreviated cell cycle, we optimized a protocol for expansion microscopy in stem cells of the reproductive system of the model organism C. elegans. Optimizations included development of new mounting techniques and modifications to DNA staining methods. These optimizations produced brighter samples that were easier to find and focus on at the microscope. These optimizations, combined with future labeling of DNA replication, will expand our understanding of how cells with an abbreviated cell cycle maintain genome stability.

Available in PDF, EPUB and Kindle. Book excerpt: Efforts to model computation in biological neural networks require knowledge of the structure of the network, the dynamics that play across it, and a network simple enough to be tractable to our incipient analyses. The simplicity of the 302-node nervous system of the nematode C. elegans and its transparency have made it an attractive model organism in neuroscience for several decades. Indeed, Caenorhabditis elegans has long been touted as the only species for which the connectome is known, reconstructed by hand from electron micrographs. However, while the number and identity of neurons in C. elegans appears fixed across animals, the variability in the connections between them has not been sufficiently characterized by the above efforts, which examined only a handful of animals and required many years of human labor. Such a characterization, and, moreover, an ability to accurately assess shifts in these neural graphs on timescales compatible with the pace and statistical rigor of scientific research would significantly accelerate efforts to understand neural computation. This thesis lays the groundwork for the development of such a framework. The expansion microscopy tissue preparation platform provided the basis for the set of experiments described within, in which strategies for molecular annotation of C. elegans and the subsequent protocols for readout are examined.

Available in PDF, EPUB and Kindle. Book excerpt: Molecular biology has driven a powerful reductionist, or “molecule-c- tric,” approach to biological research in the last half of the 20th century. Red- tionism is the attempt to explain complex phenomena by defining the functional properties of the individual components of the system. Bloom (1) has referred to the post-genome sequencing era as the end of “naïve reductionism. ” Red- tionist methods will continue to be an essential element of all biological research efforts, but “naïve reductionism,” the belief that reductionism alone can lead to a complete understanding of living organisms, is not tenable. Organisms are clearly much more than the sum of their parts, and the behavior of complex physiological processes cannot be understood simply by knowing how the parts work in isolation. Systems biology has emerged in the wake of genome sequencing as the s- cessor to reductionism (2–5). The “systems” of systems biology are defined over a wide span of complexity ranging from two macromolecules that interact to carry out a specific task to whole organisms. Systems biology is integrative and seeks to understand and predict the behavior or “emergent” properties of complex, multicomponent biological processes. A systems-level characteri- tion of a biological process addresses the following three main questions: (1) What are the parts of the system (i. e.

Book excerpt: This edited volume on the nematode model Pristionchus pacificus describes an integrative approach to evolutionary biology. It aims for a merger of evolutionary and comparative biology with mechanistic approaches based on genetics and molecular biology. Insight into the function of biological systems obtained from laboratory studies when complemented with ecology, natural variation and natural history of an organism, can provide detailed knowledge of the proximate and ultimate causations of species. Ralf J. Sommer developed P. pacificus as model system for integrative evolutionary biology with case studies in evo-devo and population genetics on La Réunion Island. Similarly, ecological interactions with scarab beetles revealed examples for the evolution of novelty at the morphological and behavioural level and their underlying molecular mechanisms. Contributors include Paul W. Sternberg, Ralf J. Sommer, Jagan Srinivasan, Christian Rödelsperger, Frank C. Schroeder, Robin M. Giblin-Davis, Natsumi Kanzaki, Matthias Herrmann, Angela McGaughran, Katy Morgan, Akira Ogawa, Federico D. Brown, Ray E. Hong, Robbie Rae, Amit Sinha, David Rudel, and Erik J. Ragsdale.
