This article reviews the role of R-spondins and their receptors in bone development and metabolism, highlighting their potential modulatory effects and clinical implications for treating bone loss diseases, but reports no new clinical results.

In this study, a dual recombinase-mediated genetic system showed that cavity macrophages accumulate on the surface of visceral organs during lung and liver injury but do not penetrate or contribute to tissue repair.

This study in cashmere goats found that DNA methylation levels were lower during hair follicle differentiation compared to induction, suggesting it plays a critical role in gene regulation for hair morphogenesis.

This review discusses the role of stem cell heterogeneity and compartmentalization within the epidermis and highlights their significance as niches for neighboring cells, without reporting new experimental results.

This study found that mesenchymal stem cells, especially when injected intradermally, significantly accelerated wound healing in rats compared to chitosan treatment.

This review discusses the role of perifollicular macrophages in hair growth and suggests targeting them could be relevant for managing hair growth disorders, but reports no new results.

This study found that deletion of c-Jun and JunB in mouse bulge hair follicle stem cells was sufficient to trigger psoriasis-like skin disease through thymic stromal lymphopoietin signaling.

This study found that telomere shortening disrupts BMP/pSmad/P63 signaling, leading to skin atrophy via Follistatin up-regulation, and suggests potential therapeutic targets.

This review discusses hair follicle stem cells for wound healing and reports no new clinical results, noting their potential but emphasizing the need for further understanding and safety in clinical applications.

This article argues that lineage labeling with genetic markers is the gold standard for identifying epithelial stem cells, contrary to the view that in vitro methods alone are sufficient.

This review discusses the multifaceted roles of hair follicles in skin health, including potential contributions to skin neoplasias, and reports no new results.

This review discusses multiple pathways through which exosomes may regulate skin functions and diseases like melanoma, scleroderma, and pigmentation disorders, without providing new clinical results; future therapeutic strategies are suggested.

This study proposes a two-step method that may enhance the generation of stem-like epidermal cells with superior proliferation and differentiation potential for skin regeneration.

This study observed that aging leads to significant structural and biological changes in the scalp's hair follicle environment in women, which may affect hair growth.

This study found that a combined pattern of repigmentation was most commonly observed in vitiligo, with a new 'medium spotted' pattern proposed for areas with few hair follicles.

This study found that keratins 5, 7, 8, and 19 are expressed in human trophoblast cells while vimentin is solely expressed in stromal-mesenchymal cells, aiding in placental cell type identification.

This study found that, in Japanese patients with androgenic alopecia, sebaceous glands exhibit increased multilobulation which may be significant in the condition's pathology.

This review examines the role of stem cells and their niches in continuously growing ectodermal organs like teeth, hair, and claws, providing insights from mouse models without presenting new research findings.

This study found that single high-dose irradiation in mice induced more severe acute skin injury and hair depigmentation, while fractional doses led to longer-term damage in the dermis and subcutis.

This study found that CK15 is an unreliable marker for assessing bulge zone integrity in cicatricial alopecia follicles due to its altered expression in diseased conditions.

This article reviews recent advances and therapeutic approaches in treating alopecia areata, highlighting new potential treatments like pulse corticosteroid therapy, but reports no new research findings.

This study used single-cell RNA sequencing to create a detailed atlas of human scalp hair follicles and found that early-stage hair graying involves matrix hair progenitor depletion linked to P53 pathway activation.

This review explores the expression of Perforin by gamma delta T cells in human skin and its role in cytotoxicity but reports no new experimental results.

This review discusses the evolution of lineage-tracing strategies over the past century, emphasizing their role in identifying progenitor cells and resolving debates about cellular origins, with no new results reported.

This study found that quiescent bulge stem cells, when prevented from contributing to hair follicle and epidermal regeneration, did not affect hair follicle growth or wound healing in the short term.

In this study, researchers using the hair paradigm highlighted how periodic patterning and compartmentalization enable diverse regenerative behaviors, including region-specific renewal cycles and emergent properties like regenerative waves in organ populations.

In this study, activation of oncogenic K-ras in a mouse model caused the oral mucosa to rapidly progress from squamous hyperplasia to carcinoma within 14 days, demonstrating its acute sensitivity.

This study found that CD26+ fibroblasts are crucial for effective extracellular matrix production and achieving rapid epidermal and dermal homeostasis in human tissue-engineered skin substitutes transplanted onto rodents.

This study reviewed the prospects and challenges of using stem cells from adipose tissue in regenerative medicine for facial rejuvenation, emphasizing the need for further research to ensure patient safety before these methods can become routine in cosmetic and reconstructive surgery.

In this study, topical quercetin was found to stimulate hair follicle growth and promote microvascular regrowth in mice, suggesting its potential for hair regrowth strategies.
