Abstract
Stem cells are units of biological organization, responsible for tissue and organ development and regeneration. I study stem cell biology, aging, and the evolution of immunity using the colonial chordate Botryllus schlosseri as a model system. This organism is uniquely suited for this study because it is closely related to vertebrates, undergoes weekly cycles of stem cell mediated regeneration, is long lived and has a recognition system and robust immune system. I have led the Botryllus genome project and developed a novel method to obtain a synthetic long read sequence, identified Botryllus stem cells and stem cell niches, isolated the gene that controls self/non self-recognition and characterized its immune system on the cellular and molecular levels. Recently, I led the Botryllus atlas project to characterize the two developmental pathways, embryogenesis (sexual) and blastogenesis (asexual), revealing the unique molecular landscapes for each developmental mode and investigated the molecular clock and neurodegeneration pathways in young and old colonies and investigated the molecular clock and neurodegeneration pathways in young and old colonies. These results and the resources we developed are used by my lab and others to further study stem cell and immune cell properties during development, regeneration, transplantation, and aging.
期刊介绍：
As of January 2000, Developmental Genetics was renamed and relaunched as genesis: The Journal of Genetics and Development, with a new scope and Editorial Board. The journal focuses on work that addresses the genetics of development and the fundamental mechanisms of embryological processes in animals and plants. With increased awareness of the interplay between genetics and evolutionary change, particularly during developmental processes, we encourage submission of manuscripts from all ecological niches. The expanded numbers of genomes for which sequencing is being completed will facilitate genetic and genomic examination of developmental issues, even if the model system does not fit the “classical genetic” mold. Therefore, we encourage submission of manuscripts from all species. Other areas of particular interest include: 1) the roles of epigenetics, microRNAs and environment on developmental processes; 2) genome-wide studies; 3) novel imaging techniques for the study of gene expression and cellular function; 4) comparative genetics and genomics and 5) animal models of human genetic and developmental disorders.
genesis presents reviews, full research articles, short research letters, and state-of-the-art technology reports that promote an understanding of the function of genes and the roles they play in complex developmental processes.
