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 review explains how recent understanding of Wnt signaling regulation in hair follicles could potentially be used to enhance hair growth, but it reports no new empirical results.

This review discusses the roles of tissue-specific and mesenchymal stromal cells in tissue repair and reparative disorders, highlighting potential therapeutic targets for muscle, heart, and lung tissues.

This review discusses the developmental regulation of wound healing mechanisms in mammals, focusing on the role of the Wnt and TGF‐β signaling pathways, and reports no new clinical findings.

This study found that keratinocytes show increased expression of the TGF-β system and collagen type I with age, suggesting a heightened profibrotic response during skin differentiation associated with scarring.

In this study, researchers found that miR-3606-3p is significantly downregulated in skin fibrosis and correlates with disease severity, with its ability to inhibit key signaling pathways suggesting potential therapeutic applications for conditions like systemic sclerosis and keloids.

This study found that neural stem cell extract enhanced hair growth in mice and cells by stimulating hair follicle niches and activating signaling pathways like TGF-β and BMP.

This study found that extracellular vesicles derived from mesenchymal stem cells and umbilical cord blood plasma enhanced wound healing and reduced scar formation in mice, suggesting their potential as therapeutic agents for skin repair.

This study found that injecting keratin into the skin of mice promoted hair growth, potentially through keratin's interaction with hair-forming cells and changes in the microenvironment.

This study found that transplanting hair follicles into human scars may remodel fibrotic tissue and reduce scarring by altering collagen structure and decreasing pro-fibrotic factors.

This study found that methionine supplementation improved hair follicle density in heat-stressed Rex rabbits, likely through various signaling pathways, despite an increase in stress indicators.

This study found that knocking down P-cadherin expression in cultured human hair follicles recreates the hair abnormalities seen in patients with hypotrichosis with juvenile macular dystrophy.

This study found that specialized nipple epidermis in mice is maintained by the repression of TGFβ signaling through estrogen, which highlights the role of hormonal regulation in epidermal maintenance.

This research reported that KDML105 bran extract demonstrated antioxidant activities, reduced nitric oxide production, and influenced gene expression related to the hair cycle in cultured dermal papilla cells, suggesting potential as an anti-hair loss agent by supporting the anagen phase and angiogenesis.

In this study, the expression of certain hair follicle-related genes differed between growth phases in Angora goats, with HOXC13 showing overexpression during the anagen phase, potentially influencing the mohair's shine and texture.

In this study, researchers evaluated the hair growth-promoting effects of strawberry water-extract on human follicle dermal papilla cells and found it enhanced cell metabolism, though it did not significantly alter hair growth-related gene expression.

This study reported that alopecia in giant pandas may be linked to abnormal expression of several hair-related genes and pathways, providing insight for potential prevention and treatment strategies.

Veratric Acid may help promote hair growth and reduce hair loss.

This study using scRNA-seq on 96 skin biopsies from 51 healthy individuals revealed distinct cell signaling pathways in different skin sites, including unique pathways in facial and palmoplantar skin, which may explain their varying susceptibilities to skin disorders.

Ashwagandha-derived nanoparticles can promote human hair growth.

This study examined Ashwagandha-derived exosome-like nanoparticles and found that they increased hair growth markers and hair shaft production in human hair follicles ex vivo, suggesting potential for plant-derived exosome therapies in hair loss treatments.

This study found significantly higher P-Smad2 levels in both lesional and nonlesional skin of organ transplant recipients, suggesting elevated TGF-β signaling might contribute to their increased cancer susceptibility.

In this study of Angora goats, researchers found that HOXC13 and other genes were overexpressed during the active hair growth phase, suggesting a role in mohair structure.

This study found that HOXC13 gene expression was significantly higher during the anagen phase in Angora goats, potentially contributing to the mohair's shiny and silky nature.

This study found that DPP4 inhibition in mice can enhance hair follicle activation and regeneration, suggesting a potential therapeutic strategy for improving hair growth and wound-induced hair follicle neogenesis.

This study found that ultraviolet radiation causes significant damage to human hair follicles, including increased cell apoptosis and oxidative DNA damage, but this damage may be mitigated by topical caffeine.

The study suggests that variability in platelet-derived growth factors in PRP is influenced by both patient-to-patient differences and the devices used for PRP preparation, contributing to inconsistent clinical outcomes in hair loss treatments.

This study found that stimulating olfactory receptor OR2AT4 in human hair follicles with Sandalore® may slow catagen development and reduce keratinocyte apoptosis, suggesting potential implications for hair growth management.
