This study observed that a topical serum containing Silybum marianum extract, manganese PCA, and Lespedeza capitata extract enhanced hair follicle growth and hair shaft elongation, while prolonging the anagen phase in an ex vivo human scalp skin model, suggesting potential benefits for hair loss treatment.

In this study, chick embryo extract enhanced neuronal differentiation and trophic factor expression in rat hair follicle stem cells, suggesting potential improvements for stem cell therapies in neurodegenerative diseases.

PRP preparation partially activates platelets, causing varied growth factor release.

This study suggests that APC collagen peptides may accelerate hair growth and promote overall hair health by enhancing cellular proliferation and activating specific signaling pathways in human and mouse models.

The researchers reported that sulfated chitosan-containing sponges can modulate macrophage activity in diabetic wounds, reducing inflammation and promoting angiogenesis and tissue regeneration, which may enhance wound healing outcomes.

In this case report, a 36-year-old woman with systemic lupus erythematosus and alopecia related to discoid lupus erythematosus showed hair regrowth following treatment with concentrated growth factor, suggesting its potential as a cosmetic therapy for DLE.

This study reported that in patients with androgenic alopecia, platelet-rich plasma therapy's effectiveness in enhancing hair density and caliber was positively correlated with specific growth factor concentrations, notably glial cell-derived neurotrophic factor and platelet-derived growth factor-BB, while no significant correlations were found with demographic factors.

This study found that platelet dry powder can be mass-produced from pig blood by adding calcium chloride, resulting in a stable material with high growth factor concentrations, which could enhance supply for industrial product development.

This study found that mature adipocytes can dedifferentiate into fibroblast-like cells, driven by PDGF and TGFβ signaling, which may play a role in wound repair and fibrosis.
