This review discusses how macro-environmental factors such as intradermal adipose tissue and sex hormones influence hair and feather stem cell niches, suggesting environmental targets for regenerative medicine, but reports no new clinical results.

This review discusses the distinction between platelet-rich plasma and stem cell-based therapies in regenerative medicine, highlighting their different roles and stressing the importance of honest representation by commercial and health entities.

This study found that multipotent neural crest stem cells from hair follicles require a full set of reprogramming factors for induced pluripotent stem cell induction, similar to fibroblasts.

This study found that VE-cadherin and Alk1, traditionally linked to vascular functions, also play crucial roles in maintaining nerve homeostasis in mice during hair growth cycles by modulating certain cell populations.

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 biology of hair follicle stem cells and highlights their potential for applications in regenerative medicine, drug, and gene delivery, but reports no new clinical results.

This study reports that epidermal neural crest stem cells from dogs (cEPI-NCSC) can generate neural crest derivatives and may offer a new cell-based therapy for canine spinal cord injury, with potential as a model for human treatments.

This case study reported that a 51-year-old woman with hirsutism and voice thickening had a Leydig cell tumor detected by PET-CT, which normalized hormone levels and resolved symptoms after surgical removal.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

This study found that human hair follicle-derived mesenchymal stem cells can differentiate into myogenic, osteogenic, adipogenic, and chondrogenic lineages, although this potential decreases over time and varies by lineage.

This study found that stem cells can temporarily act as non-professional phagocytes during hair cycle regeneration by clearing apoptotic cells through a process requiring local lipids and retinoids for activation, providing insights into their dual role in maintaining tissue integrity.

This study found that maintaining a low level of Wnt/β-catenin activity is crucial for mammary gland development, as excessive activity inhibits branching and promotes characteristics of hair follicles instead, highlighting its role in skin appendage identity decisions.

This review examines apoptotic and anti-apoptotic mechanisms in skin homeostasis and related diseases but presents no new research findings.

This study found that the postnatal thymus contains a population of mesenchymal stem cells that may help maintain functional thymic microenvironments.

This article reviews the development and use of induced pluripotent stem cell models and artificial organoids for studying neurodevelopmental disorders, but it reports no new clinical findings.

This review assessed the potential of mesenchymal stem cell therapy to enhance burn wound healing, highlighting its capabilities in promoting angiogenesis, reducing inflammation, and regenerating damaged tissues, while identifying preclinical and clinical challenges that need addressing to optimize treatment outcomes.

This review examines recent findings on COVID-19 pneumonia treatment using mesenchymal stem cells and reports no new clinical results; the authors highlight MSCs' potential due to their immunomodulatory and tissue-regenerative properties.

This study suggests that Keratin 6hf may be a potential marker of oral squamous cell carcinoma and could play a role in its progression, though further research is needed to understand its function.

This review discusses the potential of mesenchymal stem cells from the oral cavity for tissue regeneration in oral and maxillofacial surgery but reports no new clinical results.

Understanding skin structure and development helps diagnose and treat skin disorders.

This study found that activating Wnt/beta-catenin signaling in hair follicles is sufficient to induce adipocyte generation in the dermis, affecting both hair follicle stem cell activation and adipocyte differentiation.

This review summarizes fundamental concepts and recent advancements in hair follicle biology, including insights from mouse models into broader molecular and cellular processes relevant to regeneration and development.

This paper provides a comprehensive review of melanocytes' roles in skin biology, focusing on their pigmentation and immune functions, and suggests potential research opportunities for preventing and treating skin disorders.

Hair loss in androgenetic alopecia is caused by genetic factors and androgen excess, and can be treated with combined therapies.

This study demonstrates that canonical Wnt signaling is crucial for maintaining thymic epithelial microenvironments in postnatal thymus, possibly by affecting TEC progenitor cells.

This review discusses melanocytes' role in pigmentation, their clinical significance in conditions like vitiligo and hair graying, and highlights current research on hair follicle regeneration without reporting new clinical results.

This article reviews methods to enhance epithelial–mesenchymal interactions for hair follicle bioengineering but does not present new experimental results; it emphasizes optimizing combinations for successful regeneration.
