This study found that transplanting cell aggregates from mouse skin and lung mesenchymal cells can regenerate hair follicles in immunodeficient mice with skin wounds.

This study demonstrated that human dermal mesenchymal stem cells can be differentiated into cardiomyocytes using 5-azacytidine, suggesting potential future applications for treating myocardial infarction.

This study suggests that rather than inhibiting IL-15, selectively stimulating IL-15Ra-mediated signaling could be beneficial for managing alopecia areata and possibly other inflammatory hair loss conditions, as IL-15 promoted hair growth and maintained immune privilege in human hair follicles.

This review discusses the classification and diagnosis of primary scalp alopecia, focusing on scarring and non-scarring types, and reports no new clinical results; it emphasizes simplified diagnostic pathways and tissue processing techniques.

This study reported the successful isolation of epithelial stem cells from mouse embryonic skin using a simple culture method, with the cells showing the potential to differentiate into multiple cell types.

The study suggests that a 3D culture system using the RAD16-I peptide scaffold can help restore the original phenotype of hair follicle dermal papilla cells and support their osteogenic and adipogenic differentiation.

This review discusses the identification and roles of different epidermal stem cell types in skin homeostasis and repair, and reports no new experimental findings.

In this study, researchers developed a new 3D skin equivalent assay using mouse epidermal and dermal cells that successfully regenerated organized hair follicles, outperforming a 2D model in hair follicle orientation and quantity, and enhanced hair growth when Wnt3a was added.

This study found that the M5 isolation method for human dermal papilla cells significantly improved attachment efficiency, proliferative capacity, and trichogenic potential, providing an optimized strategy for scalable manufacturing in hair regeneration therapies for conditions like alopecia.

This study found that forming spheroids using silicone micro-wells improved the viability and neural differentiation potential of human adipose-derived stem cells after thawing.

This study found that acne inversa is primarily an epithelial-driven disease, with cyst-forming tendrils causing inflammation due to rupture and the release of debris, highlighting limitations of punch biopsies for analysis.

In this study using diabetic rat models, the combination of AMD3100 and low-dose FK506 reduced wound healing time and improved microcirculation in diabetic foot ulcers, indicating a promising new systemic therapy.

This study found that ovine dermal papilla cells exhibit robust aggregation and alkaline phosphatase activity, regulated by Wnt/β-catenin signaling, providing insights for improving wool performance and hair regeneration therapies.

This study developed a new human hair research model combining 3D spheroid dermal papilla fibroblasts with plucked anagen hair shafts, potentially improving the evaluation of hair follicle differentiation.

This study found that CRABP1, Nestin, and Ephrin B2 are expressed in both the tumor stroma and invasive front of skin adnexal tumors and basal cell carcinomas.

This review discusses the immune functions of porcine skin and proposes a classification of dendritic cell subsets based on similarities to human skin, but it reports no new clinical results.

This study demonstrates that Sox2-positive dermal papilla cells specify particular hair follicle types by showing heterogeneity in gene expression and pathway activation in these cells.

This study suggests that human mesenchymal stem cells have the potential to differentiate into dermal papilla cells both in vitro and in vivo.

In this study, hair follicle-derived mesenchymal stromal cells showed potential for immunomodulation, with equivalent or superior responses compared to those from adipose tissue, suggesting a promising alternative cell source.

This study demonstrated that combining AMD3100 with low-dose tacrolimus in a stem cell mobilization approach significantly reduced wound healing time and improved scar and hair follicle regeneration in full-thickness skin wounds.

This study found that quercetin significantly promoted proliferation and inhibited apoptosis of hair follicle stem cells from Arbas cashmere goats, suggesting potential benefits for improving cashmere production.

In this study, researchers found that topical application of the diabetes medication Sitagliptin in mice accelerates hair follicle regeneration and reduces fibrosis, suggesting it could be repurposed to treat hair loss conditions like alopecia.

The study suggests that refractory chronic alopecia areata cases have more infiltrating skin resident memory T cells, and using a JAK inhibitor may be an effective treatment option.

This study concluded that using human umbilical cord blood mononuclear cells transfected with VEGF and FGF2 genes enhances skin wound healing in rats, demonstrating greater wound revascularization compared to controls.

This review discusses the potential markers for identifying and studying stem cells in the epidermis and hair follicles, highlighting their role in understanding skin disease pathogenesis and expanding therapeutic options, but reports no new findings.

This study suggests that cutaneous lymphadenoma is a distinct benign lymphoepithelial tumor characterized by androgen receptor expression, hair follicle stem cell markers, and common EGFR gene mutations.

Krox20 is crucial for hair growth and maintaining skin stem cells.

CEC levels may be a useful marker for predicting prostate cancer progression.

This review examines current knowledge on human epithelial hair follicle stem cells, their markers, and outlines challenges in translating findings from murine studies to human research, but does not report new experimental results.

This study observed that quiescent label-retaining cells in the intestine, identified by Paneth cell markers, can switch to a proliferative state and activate Bmi1 expression during tissue injury, contributing to tissue regeneration.
