Hair follicle dermal stem cells help control hair growth timing by regulating signals at the hair germ–dermal papilla interface.

This article discusses the role of hair follicle stem cells in potential breakthroughs for hair cloning and follicular cell implantation, but reports no new clinical findings.

This study found that forming spheroids using silicone micro-wells improved the viability and neural differentiation potential of human adipose-derived stem cells after thawing.

This study observed that tissue-engineered skin, using VEGF165 gene-modified cells embedded in astragalus polysaccharide-containing 3D printed scaffolds, enhanced early vascularization, and collagen and hair follicle regeneration, leading to improved skin repair in nude mice with full skin defects.

This study found that LEDs at specific wavelengths may improve antifungal performance and promote hair growth by activating scalp cells without inducing inflammation compared to a non-irradiated group.

In this study, dried Gambhari fruit extract was found to increase cell viability and growth of human follicle dermal papilla cells in vitro, showing potential hair growth-promoting activity comparable to Minoxidil 5% at selected concentrations.

This study found that human hair follicle-derived mesenchymal stem cells demonstrated enhanced wound healing capabilities compared to umbilical cord-derived stem cells in laboratory and animal models.

This study notes the ongoing challenge in developing new drugs for androgenetic alopecia, mentioning that both minoxidil and finasteride were originally intended for treating hypertension. Results are not reported.

This study found that calanthoside, a compound isolated from Calanthe species, promotes the proliferation of human hair follicle dermal papilla cells more effectively than minoxidil.

In an in-vitro study, researchers found that a specific concentration of Aloe Vera combined with injectable platelet-rich fibrin (i-PRF) significantly increased hair follicle stem cell proliferation compared to Aloe Vera or i-PRF alone, indicating potential benefits for alopecia treatment.

This study showed that exosomes from hyaluronic acid-primed induced mesenchymal stem cells promote hair growth by enhancing proliferation and migration of hair follicle dermal papilla cells and modulating key growth factors and signaling pathways, potentially counteracting the effects of DHT-induced hair loss.

This study found that BMPs can counteract the inhibitory effects of androgens on hair follicle stem cell differentiation, highlighting their critical role in the pathway dysregulation seen in androgenetic alopecia.

In this study, Biofield Energy Healing significantly increased the proliferation of human hair follicle dermal papilla cells in vitro, suggesting potential as a hair growth promoter.

This study found that Biofield Energy Healing significantly increased the proliferation of human hair follicle dermal papilla cells in vitro, suggesting it may promote hair growth.

This study confirmed that porcine platelet-rich plasma could commercially replace fetal bovine serum due to its higher growth factor levels and effectiveness as a hair growth promoter comparable to existing serum.

This study found that exosomes from hyaluronic acid-primed mesenchymal stem cells may promote hair growth in androgenetic alopecia by improving hair follicle cell function and restoring key signaling pathways disrupted by DHT.

This study found that the Bioengineered Exosomal Hair Growth Factors Complex (BEHC™) enhanced human follicle dermal papilla cell proliferation and reduced inflammatory markers in vitro, while significantly decreasing hair shedding and increasing hair density among participants with androgenetic alopecia in an open-label clinical study.

This study identifies a bipotent stem cell in adult hair follicles that self-renews and contributes to dermal sheath and papilla cell populations, potentially aiding hair regrowth after injury, disease, or aging.

This study found that platelet-derived growth factor signaling is crucial for maintaining the hair follicle dermal stem cell pool and supporting their regenerative capacity.

This article reviews the cellular dynamics affecting dermal papilla size in androgenetic alopecia and suggests targeting DP size could improve therapies, but it presents no new clinical data.

This review explores the role of hair follicle dermal stem cells in skin regeneration and restorative therapies, but it reports no new experimental results.

This study found that injury affects the behavior of hair follicle dermal stem cells, steering them towards recruitment into the dermal papilla, a shift influenced by the hair cycle stage.

This study identifies unique gene expression patterns in specialized fibroblasts within adult hair follicles, which advances understanding of their role in tissue regeneration.

In this small, non-randomized study, researchers reported that injecting hair-follicle-derived stem cells into the scalps of androgenetic alopecia patients improved hair density and caliber compared to a control group, suggesting potential efficacy of this approach; however, larger, randomized studies are needed to confirm these findings.

This study found that the dysfunction of hair follicle dermal stem cells with age contributes to hair follicle aging and hair loss in mice.

This study reports that in aged mice, hair follicle dermal stem cells exhibit diminished self-renewal and preferential differentiation into dermal sheath cells, contributing to age-related hair loss.

This study found that human dermal stem/progenitor cells demonstrated greater proliferation and differentiation potential than hair follicle dermal papilla cells, which showed increased expression of hair regeneration markers.

This study showed that in mice, anti-inflammatory macrophages are crucial for hair follicle regeneration in response to skin injury by activating stem cells and promoting hair growth.

This study found that Shh from neurons signals to Gli1-expressing cells in the hair follicle, cultivating a niche where these bulge cells can potentially transform into epidermal stem cells in wound healing.
