Progress in Relevant Growth Factors Promoting the Growth of Hair Follicles

This study found that VEGF stimulates the proliferation of human hair follicle dermal papilla cells via the VEGFR-2/ERK pathway, without involving p38, JNK, or AKT signaling.

This study found that the absence of Ctip2 in epidermal keratinocytes led to impaired wound healing in mice, affecting cell migration, proliferation, and hair follicle stem cell maintenance.

In this study, IGF-I was shown to enhance human hair follicle growth, maintain the anagen phase, and increase expression of certain growth factors and anti-apoptotic markers.

This study identified TGF-β2 as a crucial signal in hair follicle stem cell regeneration, highlighting its role in counteracting BMP signaling to promote tissue regeneration.

In this study, adenosine was found to stimulate hair follicle growth in vitro by promoting growth factor expression, β-catenin activation, and downstream signaling pathways.

This study explored the effects of a new narrow-band red LED light on hair growth in mice, showing potential benefits compared to existing laser therapies.

This article examines the role and composition of integral hair lipids in forming a protective barrier similar to the skin's epidermal lipid layer and reports no new findings about their effects.

Eating isoflavone can help mice grow hair by increasing a growth factor.

This study found that cow placenta extract increased hair follicle size and hair length in mice but was less effective than minoxidil, suggesting potential with further refinement.

This study found that increased expression of type II 5α-reductase, androgen receptors, and Hic-5/ARA55 in dermal papilla cells upregulates androgen sensitivity, playing a key role in androgenetic alopecia pathogenesis.

This study found that in mice, inactivating beta-catenin in the dermal papilla reduces hair follicle progenitor proliferation and disrupts the hair cycle.

In this study, Waved-5 mice with reduced EGFR signaling showed nearly normal skin and hair follicle function but experienced a transient reduction in subcutaneous fat.

This review discusses the role of dermal cells in hair follicle regeneration and morphogenesis and highlights their potential therapeutic implications, but it reports no new empirical findings.

This review discusses various approaches to treating alopecia, including drug therapy and hair transplantation, but reports no new research findings; the authors highlight the need for novel techniques like cell culturing.

This study found that C. obtusa oils promoted hair growth in shaved mice and increased the expression of a hair growth regulator, VEGF, in a cell line.

This study found that downregulation of EGF and KGF signaling is necessary for hair follicle initiation in placodes, revealing a new role for KGF in hair follicle formation in mice.

This paper discusses the role of epidermal growth factor receptor blockade in altering skin and hair growth, highlighting hair growth stimulation as a potential side effect of cancer therapy; it reports no new experimental results.

This review summarizes fundamental concepts and recent advancements in hair follicle biology, including insights from mouse models into broader molecular and cellular processes relevant to regeneration and development.
