This study found that the Stem Cell Educator therapy improved hair regrowth and quality of life in patients with severe alopecia areata by restoring immune balance and protecting hair follicles from autoimmune damage.

This study expands knowledge of non-coding RNAs in goats and other mammals, enhancing understanding of their roles in hair follicle growth and regression.

This study found that C. obtusa oils promoted hair growth in shaved mice and increased the expression of a hair growth regulator, VEGF, in a cell line.

This study found that phosphatidic acid promotes hair growth by stimulating cell proliferation and protecting against apoptosis in murine hair epithelial cells, unlike lysophosphatidic acid, which showed limited effects.

This review discusses the role of activin signaling in hair follicle formation, hair growth cycling, and skin healing, but presents no new clinical findings.

This review discusses the role of tumor suppressors in controlling tumor-associated inflammation and suggests that targeting this inflammation may counteract the effects of tumor suppressor loss.

This study identified a critical NF-κB-LHX2-TGFβ2 signaling pathway essential for primary hair follicle development in mice, revealing new insights into the underlying mechanisms of morphogenesis.

This study found that disrupting Smad4 signaling in young mice led to overactivation of follicle stem cells, causing hyperplasia and depletion of the stem cell niche.

This study found that hydrogen peroxide interfered with scarless healing in a murine fetal wound repair model, potentially by inducing transforming growth factor-beta1, which may contribute to increased fibrosis.

This review discusses current and potential treatments for alopecia areata, focusing on immunosuppressive and immunomodulatory approaches, but provides no new clinical results.

This review discusses the potential role of extracellular vesicles in modulating hair follicle dynamics and reports no new clinical results; future investigations may inform treatment strategies for skin disorders.

This study found that dermal papilla and dermal sheath cells from human scalp tissue differ from interstitial dermal fibroblasts in morphology and produce varying levels of TGF-beta 2.

This study developed a validated murine model of hypertrophic scar contraction, demonstrating similarities to human skin and observing graft contraction and tissue characteristics over time.

This research discusses a novel imaging approach in live mice to study stem cell and niche interactions in tissue homeostasis and reports no new results.

In this study, Hedgehog signaling in dermal papilla fibroblasts was found to accelerate hair growth and induce follicle multiplication in mice via the SCUBE3/TGF-β pathway, with some effects observed in human scalp hair follicles.

This study found that PlncRNA‑1 may enhance the proliferation and differentiation of hair follicle stem cells by upregulating the TGF‑β1-mediated Wnt/β-catenin signaling pathway.

This study found that P311 triggers transdifferentiation of epidermal stem cells into myofibroblast-like cells via TGFβ1/Smad signaling during wound healing.

In this study, Salvia plebeia extract promoted hair growth by enhancing proliferation and anti-apoptotic effects in human dermal papilla cells and increased hair growth in treated mice.

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 study identified distinct gene expression patterns in wool follicle bulbs that may play important roles in wool follicle cycling and regeneration in sheep.

The researchers reported that minor salivary gland stem cells exhibit stem cell characteristics and respond to tobacco-derived carcinogens, implicating the transforming growth factor beta pathway in their maintenance.

Two studies in Cell Stem Cell reported that human and mouse somatic cells can be reprogrammed into induced pluripotent stem cells using microRNAs, eliminating the need for ectopic protein expression.

This study reported that using platelet-rich plasma as a storage medium for hair grafts in hair restoration surgery may improve graft survival rates and accelerate healing.

This study identifies cartilage oligomeric matrix protein (COMP) as a key extracellular matrix component in human hair follicle cycling, potentially regulated by TGFβ signaling, and suggests its importance in normal hair follicle biology.

This study observed that human anagen hair follicles can grow in vitro when maintained serum-free, with possible implications for understanding hair follicle growth mechanisms.

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 in vivo bioluminescence can track Smad2/3-dependent TGF-β signaling during the wound healing process in mice, with signaling increasing after healing rather than immediately post-wounding.

This study observed that reduced activation of SMAD2/3 proteins in cutaneous squamous cell carcinoma tissue compared to adjacent tissue may indicate a tumor suppressor role in disease progression.

This study suggests that abnormal hair cycles in Hr mutant mice may be caused by HR protein overexpression, which down-regulates miR-31 and increases Tgf-β2 expression.

This review discusses mechanisms of wound healing impairment in leptin-deficient murine models used for diabetic research, and reports no new clinical results; the authors emphasize the need for further study.
