This article reviews the complex signaling pathways between epithelial and mesenchymal cells crucial for hair follicle morphogenesis, highlighting the Wnt pathway's role as a master regulator without reporting new experimental findings.

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 review discusses the dynamic, niche-driven regulation of stem cell states in tissue homeostasis and regeneration, focusing on epithelial stem cells in the mammalian skin, intestine, and lung, without providing new experimental results.

This study observed that autologous platelet-rich plasma treatment improved hair count and density in areas with androgenetic alopecia compared to placebo, with differing outcomes based on the PRP collection device used.

This study found that red ginseng oil may enhance hair growth and protect skin from UV damage in mouse models by promoting regenerative processes and reducing inflammation.

In this study of patients with Androgenic Alopecia, micro-grafts containing HD-AFSCs resulted in significantly improved hair density and follicle count over 11 months compared to a saline solution, suggesting a potential alternative therapy for hair regrowth.

This review discusses the use of Dermal Papilla cells as in vitro models for studying hair growth modulators, emphasizing their role in aiding the development of new hair treatments, but reports no new clinical results.

This study reports that permanent and severe alopecia is a newly identified complication of the FEC 100–docetaxel regimen used for adjuvant breast cancer treatment.

This article reviews the generation of complex integument patterns through genetic, chemical, and environmental influences, with applications in tissue engineering, but reports no new experimental results.

In this study, patients receiving adipose-derived stromal vascular cell transplantation for alopecia areata experienced significant hair regeneration, increased growth, and improved hair quality after 3 and 6 months, indicating potential efficacy of this stem cell-based therapy for hair loss.

This study found that using 3D Gel-C6S-HA scaffolds seeded with VEGF165-modified rat hair follicle stem cells enhanced angiogenesis and vascularization in tissue-engineered skin, improving wound healing.

In this study, the researchers reported that activin B combined with bone marrow-derived mesenchymal stem cells enhanced wound healing and hair follicle regeneration in rats by promoting cell migration through the ERK and JNK pathways.

This study found that micrografts containing human hair follicle mesenchymal stem cells significantly increased hair count and density compared to placebo over 58 weeks in patients experiencing hair loss.

This review discusses various plants and herbal formulations traditionally used for hair growth and notes their potential as safer alternatives to synthetic hair loss treatments, but reports no new clinical results.

This study found that sweat gland stem cells primarily maintain sweat gland homeostasis but can trans-differentiate to aid in epidermal healing and regenerate diverse skin structures under certain conditions.

This review outlines the current state of freeze-dried platelet-rich plasma (FD-PRP) research, emphasizing its use in wound healing, lumbar fusion, knee conditions, and dentistry, but reports no new clinical findings.

The study suggests that a 3D culture system using the RAD16-I peptide scaffold can help restore the original phenotype of hair follicle dermal papilla cells and support their osteogenic and adipogenic differentiation.

This study found that ancient and modern Chinese goats share close genetic ties, originating from the Fertile Crescent, with genetic divergence influenced by China's climatic divisions.

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 platelet-rich plasma was effective for hair regrowth in women with androgenic alopecia, though less so than minoxidil, but it was associated with improved quality of life responses.

This study found that combining micro-needling, low-level laser therapy, and autologous non-activated platelet-rich plasma increased hair density in patients with androgenic alopecia over the treatment period.

This study found that 5% primed conditioned medium from human umbilical cord blood-derived mesenchymal stromal cells significantly improved hair density, thickness, and growth rate in patients with androgenetic alopecia.

This review discusses emerging targets for developing drugs to treat hair loss and reports no new clinical results; the authors emphasize the potential for therapies that regenerate hair follicles.

In this study using diabetic rat models, the combination of AMD3100 and low-dose FK506 reduced wound healing time and improved microcirculation in diabetic foot ulcers, indicating a promising new systemic therapy.

In this study, the researchers found that the effectiveness of a 1,550-nm fractional laser in promoting hair growth in mice depends on the specific combination of beam energy and density, with inappropriate settings potentially causing ulcers or hair follicle injury.

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 introduces a five-modal microscopy technique that allows label-free, in vivo observation and quantitative analysis of various wound healing processes.

This study found that FGF5-/- rabbits exhibited a significant long hair phenotype by prolonging the anagen phase, suggesting FGF5 acts as a negative regulator of hair growth.

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 abstract discusses platelet-rich plasma therapy for patterned hair loss but provides no new clinical results, suggesting further research is needed to determine its effectiveness.
