This review discusses the physiological roles of anthrax toxin receptors CMG2 and TEM8, highlighting their influence on extracellular matrix homeostasis, angiogenesis, cell migration, and skin elasticity, and reports no new clinical results.

This study suggests that D-panthenol may promote hair growth by enhancing cell viability, suppressing apoptosis markers, and elongating the anagen phase in human hair follicle cells.

This scoping review explores devices that mechanically process lipoaspirate for cell-based therapies but finds insufficient evidence to determine their clinical effectiveness due to lack of standardization and data variability.

In this study, researchers found that treating dermal papilla cells with synovial fluid and laser photobiomodulation increases the expression of chondrocyte marker genes, indicating potential promotion of chondrogenic differentiation.

This article reviews various hair growth and hair loss treatments, noting limited new developments since FDA-approved drugs but highlights recent cosmetic surgery and potential cell-based therapies; it reports no original findings.

This study found that the transcription factor Gata6 plays a crucial role in adult mouse hair follicle regeneration by promoting the renewal and preventing DNA damage of rapidly proliferating progenitor cells.

In this study, topical quercetin was found to stimulate hair follicle growth and promote microvascular regrowth in mice, suggesting its potential for hair regrowth strategies.

This study found that direct interactions between human dermal papilla cells and melanocytes under low oxygen conditions improved cell functions and could be important for hair regeneration efforts.

This study found that PGA-4HGF nanoparticles enhanced hair growth in mice more effectively than 4HGF alone by increasing anagen phase duration and dermal papilla cell proliferation.

This study observed that, in mouse ear epidermal stem cells, a cell-autonomous size control mechanism involving the RB pathway dictates S phase entry timing based on cell size, despite external environmental variations affecting growth rates.

This chapter reviews signaling pathways related to androgenic alopecia in dermal papilla cells of balding human scalps, integrating published information and analysis of molecular interactions, without reporting new clinical results.
