This article discusses the coordinated roles of different epidermal stem cells and other cell types in the skin's wound healing process and reports no new experimental results.

This review explores recent insights into the diverse cell populations involved in skin development, homeostasis, wound healing, and cancer progression but reports no new results.

In this study, researchers found that the number of dermal papilla cells in hair follicles determines hair size and shape in mice, suggesting potential avenues for addressing hair loss.

PGD2 stops hair growth and is higher in bald men with AGA.

This review discusses advances in understanding mammalian stem cell niches, particularly in bone marrow, tooth, and hair follicle, and highlights the potential for developing therapies targeting these niches for tissue repair.

This study describes a system for generating hair follicles from dissociated cells in mice, suggesting that successful development requires a foundational epithelial platform.

This study found that glycolytic metabolism and lactate production are crucial for hair follicle stem cell activation, and manipulating these processes can stimulate the hair cycle.

This review discusses advancements in artificial skin for wound treatment and reports no new clinical findings; the authors highlight the potential of new biomaterials to enhance future skin replacement therapies.

This review discusses the multifaceted actions of metformin in polycystic ovary syndrome and reports no new clinical results; the authors emphasize metformin's potential benefits in both cardiometabolic and reproductive aspects of PCOS.

In a mouse model, this study demonstrated that a microneedle patch system using keratin and integrated with MSC-derived exosomes and UK5099 promoted hair regrowth more efficiently than traditional delivery methods.

The researchers reported that hair follicle development and commensal microbe colonization promote the accumulation of regulatory T cells in neonatal skin, with the Ccl20-Ccr6 pathway playing a key role in this process.

This review discusses the role of regulatory T-cells in tissue repair and regeneration across various organs and reports no new clinical results.

This study found that hMSC secretomes from umbilical cord Wharton's jelly had the most potent angiogenic effects, whereas those from adipose tissue demonstrated the weakest angiogenic potential.

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 reported that AA-PRP injections significantly increased hair count and density in individuals with pattern hair loss compared to baseline, demonstrating their potential for enhancing hair growth.

This study demonstrates the potential of using bioengineered follicles from adult tissue-derived stem cells for fully functional hair regeneration, illustrating possible applications in organ replacement therapy.

This study identified a distinct cytokine activation signature in alopecia areata, involving TH2, TH1, IL-23, and IL-9/TH9 pathways, suggesting potential targeting strategies similar to those in psoriasis and atopic dermatitis.

This study found that macrophages near hair follicles contribute to the activation of skin epithelial stem cells in mice, suggesting a novel role for macrophages in regulating hair growth.

This study found that squamous cell carcinomas from hair follicle stem cells are more prone to epithelial to mesenchymal transition and metastasis than those from interfollicular epidermis, due to distinct chromatin landscapes.

This study found that Wnt signalling activates hair follicle fate in hair follicle stem cells by relieving TCF3/4–TLE-mediated repression, with β-catenin being crucial for this process.

Mammalian organs regenerate using stem cells and cell plasticity, but this ability declines with age.

In this study, researchers showed that Wnt ligands secreted by hair follicle epithelium are crucial for hair follicle regeneration and may be significant for treating hair disorders like alopecia.

This review discusses epidermal stem cell diversity, revealing previously unrecognized differences in stem cell populations, but reports no new experimental results; it highlights the need for further exploration of stem cell interactions and quiescence.

This review discusses the various stem cell populations associated with hair follicles and their potential in regenerative medicine, highlighting differences between murine and human hair follicles but reports no new clinical results.

This study found that mechanical skin stretching can stimulate hair stem cell proliferation and hair regeneration by activating a complex pathway involving WNT, BMP-2, and M2 macrophages.

This forum article in BMC Biology discusses evolving views on the concept of the stem cell niche, highlighting varied mechanisms and the need for better understanding of the niche's roles and functions.

This study found that chitosan nanofibrillar scaffolds accelerated skin wound healing in mice by enhancing cell adhesion, proliferation, and regeneration of epidermis and dermis compared to other forms.

This study found that hypertrophic chondrocytes at the fracture callus border may convert to osteoblasts, influenced by vasculature and pluripotency gene expression.

This study found that hair follicle stem cells initially contribute to wound re-epithelialization, but long-lasting epidermal cells are primarily derived from a stem cell population in the isthmus portion of hair follicles.
