This study found that Ift20 is essential for hair follicle stem cell identity and hair regrowth, and it regulates keratinocyte migration during wound healing through focal adhesion integrin recycling, independently of ciliogenesis.

This study reports that tofacitinib, a JAK inhibitor, may stabilize hair loss in patients with classic lichen planopilaris and frontal fibrosing alopecia, though hair regrowth was not robust.

This study observed that human dental pulp stem cells can differentiate into adipocytes and osteocytes, but their potential for neural differentiation remains uncertain due to similar responses seen in undifferentiated cells.

This study concluded that human epidermal stem cells cultured in MEM-α and EpiLife media with growth factors show high proliferation potential and plasticity, suggesting potential use in skin regenerative medicine.

This study found that CD200-negative human hair follicle bulge cells have a higher hair-regenerative capability compared to CD200-positive cells, suggesting that reduced CD200 expression may enhance hair regeneration, providing insights for improving bulge cell-based hair restoration techniques.

This study found that hypoxia-conditioned mesenchymal stem cell exosomes increased GM-CSF and decreased IL-1 expression in a dose-dependent manner in a murine model, suggesting potential for treating androgenetic alopecia.

This study found that exosomes derived from hypoxia-conditioned mesenchymal stem cells modulated inflammatory biomarkers by decreasing CXCL12 and increasing IL-10 expression in a DHT-induced androgenic alopecia mouse model, indicating potential for treating hair loss through immunoregulation.

This study observed that exosomes derived from adipose-derived stem cells significantly enhanced bone marrow mesenchymal stem cell migration and osteogenesis, leading to improved bone regeneration in a rat model of calvarial defects.

This review discusses the heterogeneity of Tregs in normal and tumor environments, emphasizing the complexity of targeting tumor-resident Tregs while maintaining systemic immune tolerance, but reports no new findings.

This study evaluated the effects of exosome therapy from hypoxia-treated mesenchymal stem cells on a fluconazole-induced alopecia model in rats and found that it significantly reduced TNF-α and increased VEGF levels, suggesting potential as a novel regenerative treatment for alopecia.

The study introduced an advanced skin model, ImmuSkin-MT, which effectively distinguished between different strengths of skin sensitizers by mimicking the interaction of immune cells in skin tissue.

This study found that human dermal stem/progenitor cells demonstrated greater proliferation and differentiation potential than hair follicle dermal papilla cells, which showed increased expression of hair regeneration markers.

In this study, researchers used 3D bioprinting with skin stem cells and specific hydrogels to create artificial skin that successfully promoted complete wound healing and the regeneration of skin structures, including hair follicles and blood vessels, in mice.
