Research Summary:
(800 words, max)
Progenitor populations and signaling pathways important for their regulation.
Current Research:
Identification of urothelial progenitors important for formation, homeostasis and regeneration of the urothelium, and identification of urothelial cell types that give rise to bladder cancers.
Intermediate cell progenitors (green).
Keratin-5 expressing basal cells give rise to CIS, muscle invasive lesions and Squamous cell carcinoma (image is of a squamous lesion).
