This review discussed the potential of induced pluripotent stem cells (iPSCs) for hair follicle regeneration, covering current approaches and challenges, iPSC differentiation, and their possible future clinical applications in hair restoration.

This review highlights the potential of mesenchymal stem cell secretome for developing topical treatments aimed at skin regeneration and treating various diseases, but notes a lack of studies on safety, efficacy, and standardization processes for its clinical use.

The study found that CK15 expression, representing hair follicle stem cell activity, was reduced or absent in scarred primary cicatricial alopecia lesions, suggesting stem cell damage may contribute to the scarring process.

Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.

This study found that loss of the Pten gene in Lgr5+ hair follicle stem cells promoted squamous cell carcinoma formation through the Akt/β-catenin signaling pathway.

This study found that mouse astrocytes formed cell spheres on agarose surfaces, acquired stem cell-like features, and their derived stem cells effectively differentiated into neurons that helped regenerate damaged nerves.

This study suggests that minoxidil may enhance hair growth by stimulating adipose-derived stem cell motility and growth factor secretion, promoting dermal papilla cell proliferation and accelerating anagen induction.

This study found that CD34- melanocyte stem cells regenerated pigmentation more efficiently, while CD34+ cells showed potential for neuron myelination, suggesting different therapeutic applications for each population.

This study observed that epidermal-specific deletion of aPKCλ in mice disrupts hair follicle stem cell quiescence, leading to altered hair follicle cycling and skin anomalies.

This study concluded that the new subfractionation culturing method generates highly homogeneous adipose-derived stem cells with enhanced mitogenic, paracrine, and hair growth-promoting effects compared to traditional isolation methods.

This study identified a distinct CD49fhigh mesenchymal stem cell subpopulation in the dermis that supports hair follicle development and maintenance via Notch signaling activation.

This study reported that bio-pulsed avian-derived mesenchymal stem cell extracellular vesicles significantly improved cell proliferation, wound healing, and gene expression in human skin fibroblasts and hair follicle cells.

Hair follicle stem cells have significant potential for treating various disorders.

This review suggests that induced pluripotent stem cells (iPSCs) hold promise for treating chronic wounds, but further work is needed to address safety, efficacy, and translation from preclinical models to real-world applications.

This study found that 808 nm laser photobiomodulation altered mitochondrial respiration and enhanced osteogenic protein expression in human dental pulp stem cells, with the effects being dose-specific and more pronounced at 15 J/cm².

In this review, the authors highlight the crucial role of mesenchymal stem cells in dermatologic therapies, noting their potential to enhance skin structure and appearance through regenerative mechanisms like inflammation induction, angiogenesis, and recruitment of tissue-specific progenitors.

This study reported that depleting the pro-apoptotic protein Bax in hair follicle stem cells enables these cells to kill nearby viable cells by sequestering TNFα, which increases the stem cell pool and accelerates tissue regeneration, suggesting potential implications for therapies targeting tissue repair and cancer.

This study found that the deletion of soluble epoxide hydrolase (sEH) in mice altered the hair follicle cycle and increased hair growth through effects on hair follicle stem and matrix cells.

Hair follicle stem cells can become neural cells using different methods, with varying efficiency.

Lgr5 is a marker for active, long-lasting stem cells in mouse hair follicles.

This study found that induced expression of mir-302 can reprogram human hair follicle cells into induced pluripotent stem cells through a novel epigenetic mechanism involving global demethylation.

This review discusses the potential applications of adipose-derived stromal cells for treating conditions like colitis, liver failure, and more, without presenting new clinical results.

PPAR-γ agonists like pioglitazone may help manage lichen planopilaris but don't fully reverse scarring.

This study found that thyroid hormones T3 and T4 enhance keratin 15 promoter activity and stimulate CD200 expression in epithelial stem cells from human scalp hair follicles, affecting their growth and differentiation.

This article reviews treatment options for cutaneous T-cell lymphoma, including skin-directed therapies and aggressive treatments for advanced cases, but reports no new clinical results.

This study found that Secretory Phospholipase A2-IIA (sPLA2-IIA) promotes proliferation through JNK/c-Jun signaling, distinctively affecting normal stem cells and cancer cells, suggesting it as a potential target for cancer treatment.

This study found that type II diabetes inhibited hair follicle regeneration and skin cell proliferation in mice, potentially explaining reduced skin renewal and chronic wound formation in diabetes.

This chapter reviews signaling pathways related to androgenic alopecia in dermal papilla cells of balding human scalps, integrating published information and analysis of molecular interactions, without reporting new clinical results.

In this study, researchers found that the microRNA profiles of induced pluripotent stem cells (iPSCs) derived from different adult cell types are largely similar, although each line exhibits some unique gene expression, distinct from both their cells of origin and embryonic stem cells.

This study found that dietary serine levels influence hair follicle stem cells' ability to balance hair regeneration and wound repair, offering insights for potential interventions to accelerate wound healing.
