Michael M. Shen, PhD
The Shen laboratory investigates the molecular mechanisms of mammalian development and cancer using in vivo analyses of genetically-engineered mouse models. The labâ€™s studies have expanded significantly to encompass analyses of prostate epithelial progenitor cells and their roles in organogenesis and tissue regeneration, focusing on the role of the Nkx3.1 transcriptional regulator as well as analysis of cell types of origin for prostate cancer. These studies have led to the identification of a luminal epithelial stem cell as well as support for a luminal cell of origin for prostate cancer, and most recently to the establishment of an organoid culture system for mouse and human prostate epithelium.
Dr. Shenâ€™s research has also incorporated bioinformatic and computational systems approaches in studies ranging from analyses of extraembryonic endoderm stem cell differentiation to the investigation of prostate epithelial lineage specification. Ongoing projects include systems analyses of embryonic stem cell pluripotency, investigation of mechanisms of prostate epithelial lineage specification and cell-type differentiation, and generation of novel mouse models of advanced prostate cancer. Most recently, the scope of Dr. Shenâ€™s research has expanded to molecular studies of bladder cancer evolution and drug response through the analysis of patient-derived bladder tumor organoids.
