This review discusses the potential use of cultured primary fetal cells from a single organ donation to produce therapeutic products, emphasizing the need for process consistency and safety verification, but reports no clinical results.

This study reported that disrupting ephrin-Eph interactions in adult mouse skin doubled cell proliferation in the hair follicle and epidermis, suggesting ephrins as negative regulators of proliferation.

This study found that GLI2 plays a key role in activating follistatin, an activin/BMP antagonist, in response to hedgehog signaling in human epidermal cells, with implications for hair follicle development and basal cell carcinoma.

This study found that upper wound fibroblasts are crucial for hair follicle regeneration during wound healing and suggests that these cells, along with papillary fibroblasts, migrate within the wound.

This study found that local refinement of hair follicles into higher order patterns can occur without the core planar cell polarity system, but global alignment with body axes requires its function throughout development and regeneration.

This study found that human hair follicle dermal cells, specifically dermal sheath cells, can serve as an alternative and potentially superior cell source for constructing the dermal component of bioengineered skin in both in vitro and in vivo settings.

This review discusses the role of stem cells in alopecia pathogenesis, highlighting the differences between scarring and nonscarring types, and reports no new clinical results.

This review explores the role of hair follicle dermal stem cells in skin regeneration and restorative therapies, but it reports no new experimental results.

This study found that Merkel cell clusters require Frizzled6 signaling for their polarity information, while other hair follicle-associated structures align their orientation based on the hair follicle itself.

This review explores recent insights into how intrinsic gene oscillations and molecular interactions in hair follicle stem cells contribute to their regenerative potential, with potential implications for regenerative medicine, but reports no new clinical results.

This review discusses the mechanisms governing epidermal stem and progenitor cell differentiation, emphasizing the balance necessary for maintaining skin barrier function, and reports no new experimental findings.

This study found that the presence of CD3(+) T-cells within empty follicular fibrous tracts is a reliable indicator for diagnosing diffuse alopecia areata instead of pattern hair loss.

The researchers reported that hair follicle germinative epidermal cells can form complex structures when associating with papilla cells in culture, unlike other types of epidermal cells.

This study found that a novel 3D in vitro culture condition improved stemness markers and proliferation potential in human dermal stem/progenitor cells compared to traditional 2D methods.

This study describes two methods for isolating hair follicle stem cells from newborn Yangtze River Delta White Goats, highlighting differences in cell viability and marker protein expression between the methods.

This study suggests that co-culturing human outer root sheath cells with human dermal papilla cells can restore their ability to induce hair growth by altering gene expression through paracrine signaling.

This study found that using cultured mesenchymal stem cells from mouse whisker hair follicle outer root sheath in wound healing reduced inflammation, accelerated closure, and resulted in less hypertrophic scarring in mice.

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.

This study found that inhibiting the TRPV3 channel may significantly promote hair growth and suggests a potential therapeutic approach for hair loss and related skin diseases.

This case report describes a 49-year-old woman with Sweet syndrome who experienced complete resolution of skin lesions after a prednisone treatment regimen.

This study suggests that decorin may help maintain hair follicle stem cells and its reduced expression could contribute to age-related hair loss.

This study found that the expression of LRIG1 in Merkel cell carcinoma tumors was associated with improved overall and cancer-specific survival.

This study found that conditioned media from human amniotic fluid-derived stem cells may enhance skin regeneration by promoting cell proliferation and migration, and by modulating gene expressions altered by UV irradiation.

This study reported that exogenous R-spondin-1 can restore hair follicle neogenesis in adult mouse cells, highlighting differences in gene expression and signaling pathways between fetal and adult dermal papilla cells.

In this study, researchers observed that Malassezia species show different lipid metabolism and growth patterns depending on pH, with slightly acidic conditions promoting beneficial lipid bio-conversion for skin health, while neutral pH resulted in lower growth and lipid content, potentially negatively impacting the skin.

This study found that melatonin treatment increased epidermal thickness, subcutaneous fat, and dermal-related factors in postmenopausal rats, suggesting benefits for skin structure after menopause.

This study observed that skin stem cells in dogs could be identified using CD34 and CD200 markers, although further refinement in isolation and cultivation methods is needed for better identification.

This study investigated single-cell changes in photoaged skin, revealing distinct cell clusters and increased activity in PD-L1 and PD-1 pathways in sun-exposed areas, enhancing understanding of UVA-induced skin damage and potential prevention targets for photoaging and UV-induced skin cancers.

Photodynamic therapy may not work for erythroplasia of Queyrat and could lead to invasive squamous cell carcinoma.

This article discusses the role and potential of plant stem cell extracts in cosmetics for their antioxidant and protective effects on skin cells, reporting no new clinical results; the authors highlight ecological and sustainable production methods.
