In this study, researchers identified a gene regulatory network in Arabidopsis that controls root hair growth under low-temperature conditions, revealing specific transcription factors and downstream targets that contribute to this growth response despite overall plant development being halted.

This study identified a specific genetic variant in the CCHCR1 gene that may contribute to alopecia areata through impaired keratinization, suggesting an alternative mechanism beyond autoimmune causes.

This study found that molecular differences in paracrine factors between balding and non-balding hair follicles may enhance understanding of androgen action in hair disorders and potentially inform better treatments.

This study found that canine hair follicle stem cells in vitro expressed markers associated with multipotency, suggesting their potential role in the hair cycle.

This study found that TRPV1 activation in human scalp hair follicles inhibited hair shaft elongation, suppressed proliferation, and induced apoptosis, suggesting TRPV1 as a potential target for managing hair growth and epithelial disorders.

This review discusses the conserved molecular mechanisms controlling hair follicle development and cycling and suggests they may also apply to other ectodermal derivatives, like teeth and feathers, but it reports no new results.

This study found that follistatin and activin interactions are important for hair follicle development and cycling in mice, suggesting that they may regulate processes involving BMP-2 and its antagonist.

This study found that vitamin C increased the survival, proliferation, and hair-regenerative potential of adipose-derived stem cells through the MAPK pathway and enhanced hair growth in mice.

This study developed a 3D engineered hair follicle model that mimics the native hair bulb and may aid in drug screening for hair growth therapies.

This study demonstrated that topical oleuropein induced hair growth in mice by activating the Wnt10b/β-catenin signaling pathway and increasing expression of several growth-related genes in skin tissue.

This study found that neonatal mice without the urokinase-type plasminogen activator (uPA) gene had reduced epidermal proliferation rates, suggesting uPA's involvement in promoting keratinocyte proliferation.

This study found that phenyl-imidazole sulfonamide derivatives, particularly ISCK03, inhibited c-kit signaling and promoted depigmentation in various experimental settings, suggesting potential use as skin-whitening agents.

In this study, Polygonum multiflorum Radix promoted hair growth in mice, with oral administration being more effective, likely through FGF-7, while topical application favored SHH-related mechanisms.

This study found that injecting hepatocyte growth factor-enhanced hair follicle stem cells into a rat model of ischemic stroke improved recovery by reducing inflammation, protecting the blood-brain barrier, and promoting angiogenesis.

This study suggests that Platycarya strobilacea extract promotes hair growth in mice by enhancing stem cell factor expression, reducing mast cell numbers, and increasing cytokines associated with hair growth.

This study found that GPC1 is a crucial regulator of angiogenesis in human dermal microvascular endothelial cells, indicating its potential as a target for treating alopecia.

In this animal study, the researchers found that Schisandra nigra extract may promote hair growth by extending the anagen phase and reducing TGF-beta2 expression.

Among in vitro and in vivo models, this study found that Miscanthus sinensis var. purpurascens flower extract may promote hair growth, potentially by modulating growth factor expressions and facilitating earlier hair follicle transitions in treated mice.

This study found that 6-Gingerol significantly suppressed hair growth in mice by reducing hair follicle number and length, potentially through increased expression of MMP2 and MMP9.

HGF combined with ADA is highly accurate for diagnosing tuberculous pleural effusion, especially in younger females.

This study found that adding epidermal growth factor to mesenchymal stem cells enhanced wound healing and hair follicle regeneration in rats compared to stem cells alone.

In a laboratory setting, this study found that overexpression of the FGF5 short form in cultured keratinocytes increased hepatic growth factor gene expression, suggesting a potential role in hair growth.

This review discusses advancements in regenerative medicine for hair loss treatments, highlighting stem cell techniques for rejuvenating or creating hair follicles, but provides no new clinical results.

This study found that fibroblast growth factor 9, initially secreted by γδ T cells, plays a key role in modulating hair follicle regeneration in mice after skin wounds.

This study found that overexpression of Smad7 in transgenic mice led to severe alterations in multiple epithelial tissues, resulting in early death after birth.

This study found that women with nonclassic congenital adrenal hyperplasia (NC-CAH) reported lower sexual function and higher sexual distress compared to those with classic CAH (C-CAH), particularly among those showing signs of androgen excess.

This study found that stress hormones, particularly CRF, can inhibit hair growth and induce hair loss by affecting human dermal papilla cells and hair follicles, suggesting a functional HPA axis in these cells.

SPRY1 deficiency in skin cells causes stem cells to move to the skin surface, leading to increased pigmentation.

This study found that sebaceous glands in the skin are primarily renewed by their own stem cells during normal conditions, but after injury, they regenerate through stem cells from hair follicles, highlighting stem cell plasticity and regeneration capabilities.

This study found that factors released by mesenchymal stromal cells can enhance the proliferation and migration of keratinocytes in vitro, which may contribute to improved understanding of their role in wound healing and potential applications in dermal regeneration therapies.
