Tissue homeostasis relies on constant tissue renewal, notably within the rapidly regenerating intestinal epithelium. Precise control of cell proliferation during differentiation is critical for maintaining tissue homeostasis, as its disruptions lead to atrophy or cancer. Our research focuses on elucidating how cell proliferation and differentiation are orchestrated in the intestinal epithelium. In particular, we aim to uncover the molecular mechanisms underlying the cell fate decision of intestinal epithelial stem cells by live imaging of mouse intestinal organoids, multiplexed tissue imaging, and quantitative analyses.
