Dr. Xiaonan Han laboratory has been working on the roles of intestinal stem cells (ISC) during inflammatory bowel diseases (IBD), infectious gastrointestinal (GI) diseases and colorectal cancer (CRC). His lab reported that the cytokine-JAKs-STAT5 pathway is the key signaling in the regulation of the ISC response to GI inflammation and infection to promote intestinal barrier regeneration (Gilbert S, et al. EMBO Molecular Medicine 2012 and Stem Cell Reports 2015, and Liu R, et al. Life Science Alliance 2019). His current research is focused on employing compound mutant mouse lines, human or murine adult ISC-differentiated organoids and CRSPR/Cas9-edited induced pluripotent stem cell (iPSCs)-derived human intestinal organoids (HIOs) to explore how gain of niche cell function protects ISCs to improve the epithelial lineage repair during GI infection and inflammation against cancer stem cell transformation. Dr. Han is also trying to address how cytokine pathways regulate the switch between the ISC niche induced by chronic inflammation injuries and the metastatic niche during colon cancer.
