Abstract：Cells make fate decisions in response to dynamic environments, and multicellular structures emerge from multiscale interplays among cells and genes in space and time. The recent single-cell genomics technology provides an unprecedented opportunity to profile cells.  However, those measurements are taken as static snapshots of many individual cells that often lose spatiotemporal information. How to obtain temporal relationships among cells from such measurements? How to recover spatial interactions among cells, such as cell-cell communication? In this talk I will present our newly developed computational tools that dissect transition properties of cells and infer cell-cell communication based on nonspatial single-cell genomics data. In addition, I will present methods to derive multicellular spatiotemporal pattern from spatial transcriptomics datasets. Through applications of those methods to several complex systems in development, regeneration, and diseases, we show the discovery power of such methods and identify areas for further development for spatiotemporal reconstruction of single-cell genomics data.
