This study found that DECORIN promotes the proliferation and migration of outer root sheath keratinocytes in vitro and maintains the hair anagen phase in mice.

In this study, autophagy was commonly observed during keratinization in neonate rat hair follicles, suggesting lysosomal proteases and cytoplasmic enzymes may coordinate in hair follicle cell differentiation.

This study found that transgenic mice expressing HPV E6/E7 in the outer root sheath experience continuous hair follicle cycling due to delayed catagen entrance and insensitivity to telogen resting signals.

This study found that stress hormones, particularly CRF, can inhibit hair growth and induce hair loss by affecting human dermal papilla cells and hair follicles, suggesting a functional HPA axis in these cells.

This study found that COX-2 expression in normal rat skin is linked to the hair cycle, with varying levels observed in different skin structures during anagen, catagen, and telogen phases.

This study observed that amino acid uptake into wool follicles varies significantly, with cysteine showing the highest uptake rate, suggesting specialized transport systems that may influence wool growth.

This study found that human mesenchymal stem cells overexpressing JAM-A improved hair follicle structure and hair formation in mice by reducing abnormalities such as curved and zigzagged follicles.

This study found that TGF-β1 expression in follicular tumors correlates with differentiation degree and suggests its potential role alongside p63 in differentiating between sebaceous and follicular tumors.

This study found that injecting keratin into the skin of mice promoted hair growth, potentially through keratin's interaction with hair-forming cells and changes in the microenvironment.

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 found that anagen hairs require less force to be extracted than telogen hairs in an in vitro pig skin model, indicating different anchorage mechanisms.

This study found that Rab27a and Rab27b play opposite roles in hair growth, with Rab27a knockdown suppressing and Rab27b knockdown promoting hair growth in models.

In this study, the researchers developed a new protocol using human-induced pluripotent stem cells to efficiently create skin hair follicle organoids, which may aid in optimizing hair follicle growth and exploring treatments for alopecia.

This study found variable outcomes in hair loss treatment with autologous cell-based therapy using DSC cells, with certain gene markers showing inconsistent correlations with treatment efficacy.

This study found that Phaeodactylum tricornutum extract enhanced hair follicle cell proliferation, indicated by increased keratin and ERK1/2 signaling, suggesting its potential for hair care applications.

This study found that NNAT is localized in both undifferentiated and differentiated cells across various rat tissues and has cell-specific intracellular localization, suggesting distinct functional roles.

This correspondence describes two patients with both epidermolysis bullosa simplex, Dowling-Meara type, and loose anagen hair syndrome, an association not previously reported in the literature.

This study adapted a method for culturing melanocytes from human hair follicles to horses, successfully creating partially melanotic equine melanocytes, potentially advancing hair follicle biology research across species.

This study suggests that the NGF/TrkA/CREB system plays a crucial role in promoting outer root sheath cell proliferation in cashmere goats, which may aid in marker-assisted breeding.

This chapter reviews signaling pathways related to androgenic alopecia in dermal papilla cells of balding human scalps, integrating published information and analysis of molecular interactions, without reporting new clinical results.

This review discusses transplantation of melanocyte stem cells for vitiligo treatment and reports no new clinical results; it suggests the procedure could be effective in reactivating melanocyte precursors for repigmentation.

This study suggests that immunohistochemistry of keratin and involucrin expression can aid in distinguishing malignant trichilemmoma from other tumors previously diagnosed as such.

This study observed that activating the Wnt/β-catenin pathway enhances hair follicle stem cell proliferation and differentiation, promoting hair growth and wound healing, and demonstrated the potential for outer root sheath transplants to aid skin repair, although challenges remain for clinical application.

In this study, researchers used single-cell RNA sequencing to map the hair follicle microenvironment in fine-wool sheep, identifying specific cell types and gene expressions that influence wool fiber diameter, with dermal papilla cells playing a significant role in hair follicle development.

Oxytocin from hair cells helps hair growth and stem cell increase.

This study combined spatial and single-cell transcriptomics to identify that hypercontractility of the connective tissue sheath activates PIEZO1 in hair follicles, leading to miniaturization in male androgenetic alopecia, and found that inhibiting this contraction improves hair growth in models.

This study suggests that human DSCCs may aid in hair follicle regeneration and reduce microinflammation, with potential applications in regenerative medicine evaluated through a new morphometric analysis.

The authors report a rare case of trichilemmal carcinoma in the thigh of a 71-year-old, emphasizing the importance of complete surgical excision to prevent recurrence and support patient prognosis.

This study highlights that human hair follicle dermal papilla cells and glypicans play crucial roles in regulating hair follicle stem cell differentiation.

This study suggests that pilose antler extracts promote hair regrowth in androgenetic alopecia mice by activating the AKT and Wnt pathways, enhancing hair follicle stem cell proliferation.
