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 study documented distinct expression patterns of stem cell markers LGR5 and LGR6 in various human skin tumors, highlighting differences in their potential roles and contributions to tumor development.

In this study, researchers found that treating dermal papilla cells with synovial fluid and laser photobiomodulation increases the expression of chondrocyte marker genes, indicating potential promotion of chondrogenic differentiation.

This preliminary study of Alopecia Areata identified limited expression of certain metabolic transporters and enzymes in hair follicle immune cells, providing early insight into their unique energy needs.

This study identified a new subset of Ret-positive sensory neurons involved in itch perception, characterized by their unique expression profile and response to specific itch-inducing molecules.

This study found that keratin expression patterns vary within nail unit structures, with the nail matrix uniquely expressing the acidic hair-type keratin Ha1.

In this study, researchers observed that keratoacanthoma exhibits dynamic follicular differentiation throughout its stages, with changes in specific keratin expressions, and regressed lesions showing epidermal rather than follicular characteristics.

This study found that selective downregulation of CD200 in the bulge area might contribute to unusual bulge involvement in a subset of alopecia areata cases.

This study observed that nestin-positive, K15-negative cells in hair follicles may play a crucial role in hair follicle regeneration in patients with alopecia areata.

In this study, researchers reported that specific immunoreactivity patterns observed in hair follicle stem cell markers suggest different origins for trichilemmoma, basal cell carcinoma, and squamous cell carcinoma in human skin tissues.

This study found that CD90+ cells, resembling mesenchymal stem cells, are abundantly present in the lower part of anagen hair follicles in dogs.

This study found that CD90+ stem cells with fibroblast-like morphology are present in the lower part of the anagen hair follicle in dogs.

This study found that epidermal stem cells in nonglabrous skin are connected to the distal end of the arrector pili muscle, which may play a role in epidermal renewal and wound healing.

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 study found that a single application of TCDD on the skin of hairless mice altered epidermal differentiation, changing keratin expression patterns similarly to a known tumor promoter.

This study found that the absence of Ctip2 in epidermal keratinocytes led to impaired wound healing in mice, affecting cell migration, proliferation, and hair follicle stem cell maintenance.

This study found that the p63 transcription factor is expressed during rat epidermal development and may serve as a specific marker for keratinocyte progenitor cells.

CD200 is not a reliable marker for identifying stem cells in all skin types.

This study found significant differences in scalp microbiome composition and volatile organic metabolites between individuals with alopecia areata and healthy controls, suggesting potential microbiome-related therapeutic interventions for hair growth disorders.

High MUC-18/MCAM levels in blood indicate a worse outlook for melanoma patients.

Activating cAMP and ATP improves hair growth and strength.

This study identified a subtype of itch-sensing neurons in mice, which express Ret and somatostatin, and found that their ablation reduces scratching induced by certain pruritogens.

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.

Hoxc13 is important for hair and tongue development by controlling hair keratin genes.

This study reports a case of cystic panfolliculoma, highlighting the role of epithelial-mesenchymal interactions in its pathogenesis and explaining its histological resemblance to trichofolliculoma.

This study developed a new melanocyte cultivation medium without chemical mitogens, melanogenesis enhancers, or bovine products, demonstrating successful proliferation and melanotic differentiation of human melanocytes from hair follicles.

This study found that keratin 19 may be a marker for skin stem cells, helping to characterize these cells in different conditions and potentially explaining variations in healing rates between children and adults.

This study found that photoexposure significantly increased the gene expression of altered elastin, MMP12, and LOX, as well as the protein expression of tropoelastin and fibrillin-1, in skin models.

In this study, researchers found that TSPyV T antigens can disrupt normal cell differentiation and proliferation in hair follicles and interfollicular epidermis, possibly contributing to trichodysplasia spinulosa pathology.
