Oligosaccharides of hyaluronic acid increased epidermal cell stemness by modulation of integrin expression

These findings suggest that oligosaccharides of HA increase the differentiation of the epidermis. In addition, increased number of p63, a putative stem cell marker of the skin, showed that oligosaccharides of HA promote the survival of basal stem cells by modulating the expression of integrin-α6 and integrin-β1. Finally, it can be said that inflammation-induced small-sized oligosaccharides can have beneficial effects on epidermal regeneration and topically applied oligosaccharide of HA can have healing effects in skin problems.
