Research Summary:

Our work helped to establish that

  1. keratins are epithelial markers,
  2. corneal epithelial stem cells reside in the limbus,
  3. hair follicular epithelial stem cells reside in the bulge, and
  4. uroplakins are major urothelial differentiation markers.

Currently we work in a multi-disciplinary team, supported by an NIH Program Project grant, to study the structure, function and disease implications of uroplakin proteins, as well as the location and biological properties of bladder urothelial stem cells.
