Highlights

Welcome

This is a research laboratory in the Department of Pathology in the University of Southern California, Los Angeles. The major research subject is developmental biology of epithelial organ formation. The applicational side is tissue engineering, namely how to guide epithelial stem cells to form different epithelial organs: e.g. feather, hair, liver, mammary gland.

What's new?

"The Morphogenesis of Feathers" report researches that analyze the molecular pathways behind the formation of feathers in today's chicken.   It also shed new light on the origin and evolution of feathers from reptile scales.
