In this study, injections of PRP and MZT products significantly improved hair thickness, density, and count in AGA patients over six months, with variability observed in the extent of improvement between different formulations.

This systematic review found that both cellular and acellular stem cell-based therapies are safe and able to improve hair regeneration and density in patients with androgenic alopecia, although some results may be temporary.

This study found that post-hematopoietic cell transplantation epidermal grafting significantly reduced chronic wound size in patients with recessive dystrophic epidermolysis bullosa.

This study identified TSC2 as an important regulator of hair follicle morphogenesis and patterning, with Tsc2cKO mice showing altered hair patterns and frequencies compared to controls.

This study found that injection of adipose-derived adult stem cells improved hair density, thickness, and reduced inflammation in women with female pattern hair loss over 24 weeks.

Stem cell treatment improved hair density in female hair loss patient.

This study found that interfollicular injection of autologous CD34+ cell-containing PRP preparation improved hair count and thickness in patients with pattern hair loss, with better results than placental extract treatment.

In this randomized clinical trial, the authors reported that adipose-derived stem cell constituent extract topical solution increased hair density and thickness in patients with androgenetic alopecia over 16 weeks compared to placebo.

This study found that UVB irradiation alters skin stem cell niches leading to signs of photoaging, which may be reversed by adipose-derived stem cells through BMP4 pathway modulation and niche remodeling.

This study evaluated the safety and effectiveness of MNC-QQ cell therapy in five men with androgenic alopecia, reporting no adverse effects and improvements in hair growth, hair density, and quality of life over six months.

In this study, the application of human umbilical cord mesenchymal stem cell secretome significantly increased hair follicle count in fluconazole-induced alopecia in rats, although changes in epidermal thickness were not significant, suggesting a novel approach for hair restoration.

In this retrospective study, patients with cutaneous squamous cell carcinoma located in highly sun-exposed areas had a higher risk of local recurrence compared to those with tumors in less sun-exposed areas, though metastasis rates did not differ between the groups.

In this study, subcutaneous injection of mesenchymal stem cell-conditioned medium promoted regeneration of mice skin aged by D-galactose, improving skin thickness, vascularization, and collagen density.

This study reports that a combination of adult stem cell released molecules and microneedling may be an effective and safe treatment for alopecia, promoting hair regrowth in 12 patients.

This study found that TriCell CD34 + cell-containing PRP injections improved hair thickness and density in patients with alopecia after three months of treatment, with no special side effects reported.

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 found that antroquinonol inhibited CD8+ T cell proliferation and reduced proinflammatory cytokine secretion in vitro, while also ameliorating H2O2-induced depigmentation and resisting reductions in hair follicle length, skin thickness, and tyrosinase expression in mice.

In a rabbit model, this study found that the AMFIBHA skin substitute promoted wound healing and regeneration of skin structures in large-area third-degree burn wounds, suggesting potential clinical use.

This study reported that stem cells derived from semi-solid bone marrow improved the healing of diabetic incision wounds in rats by increasing epidermal thickness and blood vessel growth, and reducing hair follicle destruction, cellular penetration, diffuse fibrosis, and necrosis compared to control groups.

This study did not report conclusive results on whether a higher dose of platelets in platelet-rich plasma treatment impacts hair density, emphasizing the need for further evaluation of the trial details.

This study indicates that porcine acellular dermal matrix may aid hair follicle regeneration in mice by enhancing the expression of SDF-1 and the Wnt3a/β-catenin signaling pathway.

This study found that HB-EGF and TGF-α work together to stimulate wound healing in a murine model of thermal injury, with peak keratinocyte proliferation observed by postburn day five.

This study demonstrated that combining AMD3100 with low-dose tacrolimus in a stem cell mobilization approach significantly reduced wound healing time and improved scar and hair follicle regeneration in full-thickness skin wounds.

This study found that red ginseng extract may stimulate hair growth in a mouse model by enhancing dermal papilla cell proliferation and activating skin antioxidant defenses.

This study found that PDLLA filler treatment may help combat age-related hair thinning by reducing oxidative stress and enhancing hair follicle function in both cell and animal models.

This study found that platelet-rich plasma injections followed by mesotherapy improved hair count and thickness in alopecia patients, with no significant side effects reported.

In this study, researchers developed a biopolymer-based dual-layer wound dressing that significantly improved healing outcomes in a 14-day rat model, reporting 94% wound closure by day 15 and enhanced tissue regeneration, swelling properties, and cell viability.

In this study, a mouse model with a PIK3CA gain-of-function mutation in Schwann cells revealed unique communication with neighboring cells and a glycolytic shift in peripheral nerves, and early alpelisib treatment significantly improved symptoms, though efficacy declined with delayed administration due to limited drug penetration.

This study reports that transplantation of an ESCs-collagen-chitin biomimetic membrane leads to successful in situ skin regeneration, including hair follicle cell proliferation and formation of dermatoglyphs, in nude mice with full-thickness skin defects.

This study found that in mice, wool structure deteriorates as a malignant tumor develops, suggesting potential uses in cancer diagnostics.
