With aging, keratinocytes have diminished proliferative capacity resulting in atrophic skin with reduced barrier function. This investigation evaluates the effect of daily topical applications of a novel high-molecular weight hyaluronan cream (HA-PE) on keratinocyte renewal and epidermal thickness. Unmodified hyaluronan and HA-PE were mixed separately into a vehicle cream. Each topical formulation was applied daily onto the shaved backs of aged female C57BL6 mice. Full-thickness biopsies of treated skin were obtained for analysis of keratinocyte proliferation, keratinocyte differentiation, and local inflammation at days 1, 5, and 10 of cream application. In addition, a cardiac puncture was performed for serum C-reactive …
