Skin stem cells and the mechanism of skin repair: illustrating how skin stem cells are involved in the skin repair process.

Cell products for skin repair: the history of skin repair products and newly emerging medications applying stem cell biology.

Drug reviewing issue of skin cell products: the disputations of dermatological drug development and critical recommendations.

Stem cell products and its clinical applications have been widely discussed in recent years, particularly when the Japanese induced pluripotent stem cells founder Dr. Yamanaka was awarded as Nobel Prize laureate in 2013. For decades, major progresses have been achieved in the stem cell biology field, and more and more evidence showed that skin stem cells are involved in the process of skin repair. Stem/progenitor cells of the epidermis are recognized to play the most essential role in the tissue regeneration of skin. In this review, we first illustrated basic stem cell characteristics and various stem cell subtypes resided in the skin. Second, we provided several literatures to elucidate how stem/progenitor cells collaborate in the process of skin repair with the evidence from animal model studies and invitro experiments. Third, we also introduced several examples of skin cell products on the pharmaceutic market and the ongoing clinical trials aiming for unmet medical difficulties of skin. Last but not least, we summarized general reviewing concerns and some disputatious issues on dermatological cell products. With this concise review, we hope to provide further beneficial suggestions for the development of more effective and safer dermatological stem/progenitor cell products in the future.
