This study found that Cutl1 mutant mice experienced retarded lung differentiation and abnormal hair follicle morphogenesis, indicating the vital role of CDP in lung development and hair follicle cell-lineage specification.

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 found that prostaglandin D2 reduced proliferation in bulge resident K15+ stem cells but not in other K15+ progenitor cells, suggesting differential impacts on hair follicle stem cell niches.

In this study, luteolin-loaded nanoemulsions were shown to promote hair growth similarly to a luteolin solution in organic solvents, offering enhanced stability for follicular delivery.

This review discusses melanocyte stem cells in hair follicles and their potential role in cell-based therapy for vitiligo, reporting no new experimental results.

This study found that adapalene-loaded nanospheres in a hyaluronic acid gel enhanced skin penetration and were nonirritant, making them potentially suitable for treating acne on oily skin.

This study found that disrupting Stat3 in keratinocyte stem cells of mice reduced skin tumor formation by approximately 80%, suggesting Stat3's role in tumor initiation survival mechanisms.

This study suggests that impaired autophagy may be a potential mechanism contributing to androgenetic alopecia, as observed in miniaturized hair follicles from balding scalps.

This study found distinct differences in UEA I glycoprotein binding on follicular keratinocytes between anagen and telogen hair follicles, with staining associated with follicle length and regrowth.

This study found that the transcription factor p63 is crucial for horizontal basal cell differentiation in the olfactory epithelium, suggesting a p63-dependent mechanism activates reserve stem cells after injury.

The authors concluded that Lrig1-positive stem cells are essential for sebaceous gland formation in mice, as their ablation led to temporary sebaceous gland disappearance without affecting hair growth.

In this study, four dogs with a novel skin disease showed clinical lesions involving verrucous, crusted papules and plaques, and responded variably to immunosuppressive therapy, suggesting an immune-mediated cause.

This study found that nestin-expressing progenitor cells, capable of becoming ORS keratinocytes, are present in both developing and adult mouse hair follicles.

This study observed that Wnt5a mRNA expression in mice correlates with the hair cycle and inhibits hair follicle growth by antagonizing the Wnts pathway.

This study found that brain-derived neurotrophic factor (BDNF) inhibited hair shaft elongation and induced premature catagen development in cultured human hair follicles, partially through transforming growth factor β2.

This study found that Secretory Phospholipase A2-IIA (sPLA2-IIA) promotes proliferation through JNK/c-Jun signaling, distinctively affecting normal stem cells and cancer cells, suggesting it as a potential target for cancer treatment.

Reflectance confocal microscopy can noninvasively diagnose onychomatricoma by showing unique features different from healthy nails or nail fungus.

In this study, higher expression of PEDF was observed in hair follicles from balding regions in AGA patients, suggesting that targeting PEDF could be a promising approach for treating androgenetic alopecia.

This source describes a case of a 12-year-old male diagnosed with folliculotropic mycosis fungoides, presenting with an asymptomatic, erythematous plaque. Histology and immunohistochemistry confirmed FMF, which is typically rare in children and marked by follicular infiltration by CD4+ lymphocytes.

This study found that estrogen affected cell behaviors differently in a scratch-wound assay, increasing VEGF secretion in follicular dermal papilla cells but decreasing it in wounded dermal sheath cells.

A new method improves the isolation of hair follicle cells for better hair growth research.

This study found that intradermal adipocyte lineage cells in mice are necessary and sufficient to activate follicular stem cells, highlighting their role in regulating skin stem cell activity.

In this study, researchers found that bulge cells in mouse hair follicles undergo transient proliferation during early anagen, indicating their role as follicular stem cells. However, another factor beyond dermal papilla proximity may be required to initiate a new anagen phase.

This review discusses histologic findings in alopecia and emphasizes the importance of understanding normal follicular anatomy and cycles in transverse sections, without reporting new results.

This report documents follicular dysplasia with pigmentary changes in two adult cows, contributing to the understanding of this rare condition in cattle.

This review discusses the clinical and pathologic features of follicular contact dermatitis, highlighting neomycin as a potential cause, and reports no new clinical results.

This study identified key dermoscopic features in folliculotropic mycosis fungoides patients, showing that dilation of follicular openings and spiky follicular keratosis are specific indicators of follicular involvement, potentially aiding in diagnosis, classification, and treatment decisions.

This study identified genetic mutations linked to congenital ichthyosis in families from the UAE and Turkey, revealing a connection between keratinization disorders and impaired filaggrin processing.

This study found that finasteride (1 mg/day) appeared to reverse the shortening of the hair cycle in androgen sensitive sites but did not convert miniaturized hair into terminal hair.

This article discusses the classification and characteristics of infundibular squamous cell carcinoma and highlights the ongoing debate about its differentiation from other carcinoma types, reporting no new clinical results.
