research Cyclin-dependent kinase inhibitors, p21waf1/cip1 and p27kip1, are expressed site- and hair cycle-dependently in rat hair follicles
This study found that the expressions of CDK inhibitors p21waf1/cip1 and p27kip1 were higher during the anagen phase compared to telogen, suggesting a role in follicular epithelial cell differentiation.
