PCFCL may have unrecognized subtypes and needs more research.

This study suggests that dermal stem/progenitor cells can be enriched by intracellular granularity and display high proliferation and differentiation potential in vitro, distinguishing them from other fibroblasts and progenitors.

This study found that intradermal adipocyte lineage cells in mice are necessary and sufficient to activate follicular stem cells, highlighting their role in regulating skin stem cell activity.

The study suggests that nestin-expressing progenitor cells can differentiate into outer root sheath keratinocytes in hair follicles, indicating distinct progenitors for different hair follicle and epidermal components.

This article discusses the structure and function of the skin, the etiology and increasing incidence of skin cancer, and the types and prevalence of malignant skin tumors, but reports no new research findings.

This study demonstrated that an automated algorithm can effectively track epithelial cell movement within clusters, revealing that partial knockdown of E-cadherin reduces electrotactic potential in breast epithelial cells, particularly in free-moving clusters, and suggesting an adhesion-independent role of E-cadherin in regulating cell electrotaxis.

This review summarizes evidence suggesting that metabolism actively influences stem cell fate in intestinal and hair follicle stem cells, rather than being a mere environmental byproduct.

This study observed three hair follicle-like cells from cultured human foreskin keratinocytes, suggesting a potential basic framework for hair regeneration applications.

This review discusses the emerging roles of transit-amplifying cells in tissue regeneration and cancer formation, highlighting their significance beyond a mere transitional state in hair follicles and the hematopoietic system.

This study identified stem cells in the primary and secondary hair follicles and epidermis of Inner Mongolia cashmere goats, with BrdU labeling proving effective for up to 10 weeks.

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 nestin-GFP expressing stem cells in the hair follicle bulge of living mice using high-resolution in-vivo multiphoton tomography, allowing migration tracking within their natural skin environment.

This review explores the role and formation of stem cell niches and how they regulate stem cell self-renewal and proliferation, but it reports no new experimental results.

This review explores the multifaceted roles of melanocytes in skin biology, emphasizing their potential impact on future research to prevent and treat skin diseases, but reports no new experimental results.

This study found that CD34+ cells from adipose tissue may enhance hair morphogenesis and participate in blood vessel formation in reconstituted skin tissues of mice.

This review discusses the stem cell niche concept in mammalian systems and reports no new clinical results, highlighting recent progress and identifying important unanswered questions.

This study reported that wound-resident mesenchymal cells can be reprogrammed to generate epithelial tissues, aiding in the closure of large, non-healing ulcers without signs of malignant transformation.

This study found that fibroblasts from highly regenerative mammals, such as spiny mice and rabbits, exhibit unique metabolic characteristics, including a preference for glycolysis and specific mitochondrial features, which may contribute to their resistance to oxidative stress and support tissue regeneration.

This study revealed that nestin-expressing progenitor cells capable of becoming ORS keratinocytes are present during both hair follicle development and in adult hair follicles.

This study identified specific markers that can distinguish between stem cells in different regions of human scalp hair follicles, offering potential strategies for cell sorting and purification based on these markers.

This review explores how metabolic changes drive cellular quiescence and considers potential applications in cancer treatment by manipulating these processes.

In this study, researchers developed a detailed spatial atlas of healthy human skin and basal cell carcinoma, revealing that basal cell carcinoma likely originates from hair follicles and involves expansion of specific fibroblast subpopulations found in healthy skin.

This study suggests that interfollicular epidermal keratinocytes with stem-like features may serve as an alternative to follicular keratinocytes for hair regeneration by supporting hair follicle morphogenesis in vivo.

This study found that hyperproliferative stimuli dysregulated the balance of stem cell divisions in keratinocytes, suggesting potential treatment strategies for both benign and cancerous hyperproliferative diseases.

This report describes four trichoblastoma cases rich in Merkel cells, suggesting these tumors may mimic fetal skin development where Merkel cells are numerous.

This workshop overview concluded that follicular epithelial stem cells are multipotent and located in the bulge region of hair follicles, contributing to hair, epidermis, and sebaceous gland formation.

This study found that Hopx labels a long-lived progenitor population in hair follicles, which contributes to hair follicle stem cell homeostasis and has an alternative origin from previously thought progenitors.

This study observed dynamic behaviors such as cluster formation, migration, and active proliferation of transplanted bone marrow cells in a mouse model, providing insight into cellular-level changes post-transplantation.
