Mulitmodal Molecular Mechanisms Control Germline Stem Cell Differentiation In Drosophila, Mohamad Nasrallah

Biological Sciences

Stem cells have the intrinsic ability to divide to form a stem cell daughter, while also retaining the ability to self - renew. These qualities are critical , as improper stem cell maintenance is implicit in aging and provokes diseases such as cancer. We previously revealed that during Drosophila oogenesis, transcriptional silencing mediated by polar granule component (pgc) alters the germ line cell cycle to promote germ line stem cell (GSC) differentiation. O ur work with pgc suggested that cell cycle regulation might be an important general mecha nism to facilitate division GSCs into daughter stem cells (or cystoblast, CBs), …
