We have been awarded a NIH R35 grant entitled: “Regulation and Function of Multicellular Calcium Signaling in Epithelial Growth and Regeneration.” In this research program we seek to discover the underlying principles of integrative cell communication mediated by calcium signaling.
A long-term goal of this research is to learn how to manipulate calcium signaling to control cellular functions such as growth, motility, or death. Such knowledge will inspire methods to regulate cell differentiation for stem cell engineering applications or to stop metastatic cancers.

Simplified microfluidics and bioprinting systems for research and education.
PhD. Assistant Professor Biology Department, St. John Fisher College
Tuesday, August 8, 4-5 pm
Widespread adoption of novel research technologies is often hampered by cost and lack of equipment and expertise. Overcoming these hurdles can prove challenging. For example, improved protocols that produce reliable results may manage to reduce production time and cost of materials, but may still require procedures and/or the use of equipment not commonly available to most research and teaching laboratories. On the other hand, the quality and/or reproducibility of results obtained using low cost approaches may be compromised by the use of unreliable materials. Our goal is to provide research groups and educational settings with microfluidics and bioprinting systems that are both reliable and affordable. In the area of microfludics we describe a type of device that makes exclusive use of consumer-grade components and equipment. The user-designed devices consist of as little as three layers of a polymer film, with microchannels shaped by an inexpensive craft cutter, and sealed by thermal lamination. The chips are flexible and ten to thirty-times thinner than the common PDMS/ glass alternative. Fabrication time is in the order of minutes (allowing for rapid iteration), and the method requires very little training. In the area of bioprinting we make use of a consumer-grade 3D printer fitted with a heated nozzle which delivers a biocompatible hydrogel that sets as it comes into contact with a cooled surface. Our objective is to produce scaffolds in a variety of shapes that promote 3-dimensional arrangements of cells in culture. In summary, our systems lower the barrier-to-entry for robust microfluidic devices and biocompatible tissue scaffolds, facilitating the adoption of formerly out-of-reach technologies.

Quantitative approaches to investigating epithelial morphogenesis
Jochen Kursawe, University of Oxford, Oxford
Recently, the experimental study of morphogenesis has thrived due to a rise in quantitative methods. The resulting avalanche of quantitative data requires us to rethink the scientific method. We need to design quantitative hypotheses through mathematical models, make quantitative experimental predictions, devise methods for quantitative data analysis, and design methods for quantitative inference using models and data. This work aims to enable this transition for the integrative analysis of morphogenesis in epithelia. We conduct the first systematic numerical analysis of a widely used cell-based model of epithelia, the vertex model, and estimate to what extent quantitative model predictions may be influenced by parameter values and implementation details. We then apply this model to a key question in developmental biology by constructing a quantitative theory for tissue size control in the embryonic epidermis of the fruit fly Drosophila, using the model to predict the outcomes of future experiments. We further devise a method for estimating mechanical parameters of vertex models from imaging data and quantifying the uncertainty associated with such estimates. Finally, we propose a novel algorithm for robust cell tracking in live-imaging microscopy videos of epithelial tissues that illustrates how graph theoretic concepts may be used to overcome challenges in quantitative data analysis. Together, these contributions will enable the quantitative study of epithelia for a wide range of applications.
