Silk fibroin/hyaluronan scaffolds for human mesenchymal stem cell culture in tissue engineering.

abstract：:Topical therapy is the most favored form of treatment for whitening against hyperpigmentation and sunburn because it lends itself to self-administration, patient compliance, and absence of systemic adverse effects. However, transdermal delivery of hydrophilic chemicals is difficult. The main purpose of this study is t...
