This study found that males have significantly longer hair on their thighs compared to females, mainly due to a longer anagen phase and a greater rate of growth.

This study found that substance P may be involved in the pathogenesis of acne by increasing the expression of certain cytokines and receptors in cultured sebocytes.

This study found that the signaling peptide CLE40 and receptor proteins CLV2 and CRN regulate root meristem differentiation through two distinct, antagonistic pathways activated by CLE40 in a dose-dependent manner.

This study found that hydroxysafflor yellow A-rich Carthamus tinctorius extract promoted hair growth and gene expression linked to hair proliferation in both cell cultures and mouse models.

In this study, photodynamic therapy significantly reduced inflammatory acne lesions and sebum secretion, possibly by inducing apoptosis in sebaceous glands and down-regulating TLR-2 and TLR-4 expression.

In this study, DHT was associated with increased production of proinflammatory cytokines IL-6 and TNF-α in cultured sebocytes, suggesting a role in acne pathophysiology beyond sebum production.

This study found that protease nexin-1 mRNA is expressed in human dermal papilla cells and is downregulated by dihydrotestosterone in balding scalp, suggesting a role in male-pattern baldness progression.

In this study, researchers observed that the epidermal specializations on the tail scales of Lygodactylus lizards, including sensory organs and specific secretory glands, are fully restored with similar structure and distribution on regenerated tails.

This study suggests that skin sections from 4-week-old C3H mice could serve as an in vitro model for human androgenic alopecia, as minoxidil partially reverses suppressed hair follicle elongation.

This study found that minoxidil inhibited lens epithelial cell migration, proliferation, and collagen secretion in vitro, suggesting it may help prevent postoperative capsular opacification.

In this study, researchers found that hair follicle-derived mesenchymal stem cells, modified to overexpress extracellular matrix protein 1, significantly improved liver function and reduced liver damage in cirrhotic mice by inhibiting hepatic stellate cell activation and TGF-β/Smad signaling.

This study found that treatment with vitamin D increased the expression of LL-37 through the vitamin D receptor in cultured sebocytes.

This study found that the proteins GDNF, NTN, GFRα-1, GFRα-2, and c-Ret are differentially expressed during various stages of the human hair follicle cycle, with potential implications for hair biology.

This study found that erythropoietin promotes hair growth by stimulating dermal papilla cells with functional erythropoietin receptors, enhancing hair shaft elongation and anagen phase in cultured human hair follicles and in mice.

This study suggests that co-culturing human outer root sheath cells with human dermal papilla cells can restore their ability to induce hair growth by altering gene expression through paracrine signaling.

This study identified several genes regulated by dihydrotestosterone in an SV40T-transformed human dermal papilla cell line, which may play a role in androgen-mediated hair growth regulation.

This study observed that human anagen hair follicles can grow in vitro when maintained serum-free, with possible implications for understanding hair follicle growth mechanisms.

This study found that 15-dPGJ2 promotes apoptosis in human follicular keratinocytes, suggesting its potential role in developing hair loss prevention treatments through DP2 antagonism.

This study found that taxol induces apoptosis in dermal papilla cells, affecting protein expression related to biological processes and potentially contributing to taxol-induced alopecia.

This study found that alginate spheres maintain dermal papilla cells in a dormant state with increased trichogenecity, suggesting potential benefits for cell therapy in androgenic alopecia.

This study reported that the pseudoceramide bis-oleamido isopropyl alcohol (BOI) promotes hair growth in ex vivo cultured human hair follicles, likely by enhancing sphingolipid synthesis in dermal papilla cells.

This study reports that follicular unit grafting techniques, specifically creating a frontal forelock, achieved excellent and undetectable results in patients with advanced male pattern hair loss, leading to high patient satisfaction.

The researchers reported that follicular unit grafting in surgical hair restoration provided excellent, undetectable results and high patient satisfaction for individuals with advanced male pattern hair loss.

This study found that sheep wool follicles actively oxidize acetate and glucose, suggesting the involvement of the TCA cycle for compound synthesis and the potential role of the pentose phosphate pathway in ribose production for RNA and DNA.

This study found that topical application of triiodothyronine (T3) can induce the transition of hair follicles from the telogen to the anagen phase in mice and stimulate hair shaft growth in vitro.

This study found that the trichogenicity of cultured human outer root sheath follicular keratinocytes decreased with longer cultivation periods and was significantly influenced by the expression of the transcription factor FOXA2.

This study demonstrated that Gelfoam® histoculture supports extensive growth of both hair shafts and sensory nerves from isolated mouse whisker follicles over prolonged periods.

This study suggests that EDA-A2 induces apoptosis in hair follicles by increasing DKK-1 expression, implicating EDA2R signaling as a potential therapeutic target for androgenetic alopecia.

This study demonstrated the potential of epithelial cell scaffolds fabricated with various materials for effective hair regeneration, highlighting their promising application in tissue engineering for alopecia treatment.

This study found that multipotent neural crest stem cells from hair follicles require a full set of reprogramming factors for induced pluripotent stem cell induction, similar to fibroblasts.
