This study concluded that label-retaining cells in mouse epidermis differ in their sensitivity to proliferative stimuli, influencing their division and potential transdifferentiation without consistently depleting their population.

This review discusses the various trichoscopic features of androgenetic alopecia and alopecia areata, noting white dots in advanced cases as indicators of poor prognosis, but reports no new clinical results.

This case study reports that selenium shampoo, bacterial infection with trichomycosis axillaris, and possibly strongyloides larvae may have contributed to acquired hair shaft abnormalities resembling trichorrhexis nodosa in two patients.

This article discusses the uses and techniques of trichoscopy for hair and scalp disorders and reports no new clinical results.

This case report details atrichia with papular lesions in a 4-year-old girl, highlighting specific histological findings on her scalp and other affected areas.

This study found that trichoscopy has limited value for diagnosing telogen effluvium, as common findings are not specific enough to differentiate it from other conditions like androgenetic alopecia.

In this study, trichoscopy was found to be a valuable non-invasive tool for diagnosing scalp lesions, enhancing diagnostic accuracy and reducing the need for scalp biopsies by identifying specific trichoscopic features associated with conditions like psoriasis, seborrheic dermatitis, and alopecia areata.

This study found that trichoscopy can effectively identify specific patterns associated with Vitamin B12, Vitamin D3, and serum ferritin deficiencies in patients with Telogen Effluvium, offering a non-invasive alternative to blood tests for early diagnosis and management.

This study found that topical trypsin application after hair removal in mice led to cell death at the follicular papilla, which delayed hair growth and pigmentation.

This article describes a case of localized trichorrhexis nodosa in a patient with otherwise normal hair, highlighting the condition's response to trauma and diagnostic process but reporting no new clinical findings.

This study suggests that trichoscopy may assist in diagnosing pemphigus, particularly for scalp-specific lesions, by identifying certain characteristic features.

This study observed unexpected heterogeneity among pigment cells in human scalp hair follicles, identifying immature melanocyte populations outside traditional pigment production zones, raising questions about their potential roles beyond melanin synthesis.

This review summarizes the cell type distribution and functional significance of human keratins, emphasizing their roles in tumor diagnosis and potential clinical applications, and reports no new clinical findings.

This article reviews the complex signaling pathways between epithelial and mesenchymal cells crucial for hair follicle morphogenesis, highlighting the Wnt pathway's role as a master regulator without reporting new experimental findings.

This study identified 19 specific genes involved in root hair growth and morphogenesis in Arabidopsis, using a combination of computational and experimental methods.

This review examines the functions of vitamin D and its receptor in skin and explores how these are regulated, reporting no new clinical results.

This study found that a topical hedgehog agonist can stimulate hair growth by promoting the transition from the resting to growth phase of the hair cycle in adult mouse skin.

This study suggests that the GPX-PDE1 and GPX-PDE2 genes in white lupin enhance root hair development and contribute to Pi limitation acclimation by facilitating glycerophosphodiester degradation.

This study found that in thin cutaneous melanomas, tumor regression is associated with a higher risk of sentinel lymph node involvement.

This study found that quiescence in hair follicle stem cells acts as a tumor suppression mechanism for cutaneous squamous cell carcinoma, with Pten activity necessary to maintain this state.

In this study, topical CUR61414 was effective in inhibiting basal cell carcinomas in mice, but no clinical activity was observed in human trials.

AGD1 is important for root hair development in Arabidopsis, working with phosphoinositide signaling and the actin cytoskeleton.

This review discusses recent advancements in understanding hair follicles, their disorders, and potential therapeutic opportunities, but it reports no new clinical findings.

Scarring alopecias are complex hair loss disorders that require early treatment to prevent permanent hair loss.

This review addresses the role of skin-resident adult stem/progenitor cells in skin homeostasis, disease, and cancer development, and reports no new research results.

This study found that the receptor kinase RHS10 negatively regulates root hair growth in Arabidopsis thaliana by modulating growth duration and is associated with cell wall signal mediation, involving RNA catabolism and ROS accumulation.

This study found that glutathione deficiency affects lateral root and root hair responses to indole butyric acid in plants, but not to indole acetic acid, indicating its role in auxin pathway regulation.

This study found that root hair growth is influenced by a complex interplay of auxin, inorganic phosphate, and transcription factors RSL2/RSL4, with reactive oxygen species playing a key role in this regulation.

This study suggests that NBCCS and BFHS may be the same genetic condition, which could help improve identification and management of misdiagnosed cases with specific surveillance strategies.

This review discusses various nonfollicular scalp conditions causing secondary scarring or permanent alopecia and highlights the importance of specific diagnoses and treatments but reports no new results.
