August 2015 in “MOJ proteomics & bioinformatics” This study suggests that epithelial-derived pop-up keratinocytes (ePUKs) may improve regenerative medicine applications due to their specific phenotype and increased expression of proteins involved in regulating cellular movement and wound healing.
In this study, researchers found that crude extracts from Avicennia marina and its component avicequinone C inhibit mechanisms contributing to androgenic alopecia in vitro, including 5α-reductase activity and DHT-AR interactions, potentially promoting hair growth and delaying the catagen phase in human dermal papilla cells.
This study suggests that hair follicle dermal stem/progenitor cells play a key role in both hair regeneration and skin wound healing, with potential implications for preventing hair follicle miniaturization linked to aging or alopecia.
