This study found that immunohistochemistry can effectively distinguish between tricholemmoma and basal cell carcinoma, with BerEP4 and CD34 serving as key differentiators.

This study found that the CD44(+) ALDH(+) population of neonatal human keratinocytes exhibited enhanced stem cell properties, including significantly increased long-term epidermal regeneration and multipotency, compared to unfractionated cells.

In this study, targeted overexpression of the BMP receptor ALK2 in mouse hair follicle stem cells altered follicle structure and impaired cutaneous wound healing.

This study found that asebic mice exhibit abnormal sebaceous gland differentiation and insufficient sebum production due to defective regulation of cell processes, despite possessing normally developing sebaceous glands initially.

This study found that the development and differentiation of Merkel cells in C57BL mouse embryos' dorsolateral skin are linked to tylotrich follicle formation rather than to neural influences.

This study found that ALKBH5 plays a critical role in wound re-epithelialization by enhancing the stability of PELI2 mRNA, and its absence delays wound healing. Supplementation with PELI2 can partially rescue this delay, pointing to potential new therapies for stubborn wounds.

This case report describes a trichoblastoma in a 58-year-old man's leg, which was successfully excised without recurrence observed after 9 months.

This study found that the cytoplasmic dynein component Dynlt3 is essential for effective melanosome transport and transfer in mouse melanocytes, linking melanosome positioning and acidity to the Wnt/β-catenin signaling pathway.

The study suggests that abnormal activation of hair follicle stem cells and Wnt10b/β-catenin signaling may contribute to the development of sebaceous neoplasms.

In this study, NuMA's microtubule-binding domain was found to be crucial for correct spindle orientation and skin differentiation, with its loss leading to neonatal lethality in mice.

This study found that excess vitamin A in organ cultures of mouse embryos led to significant changes in epidermis and hair follicles, altering morphogenesis and polysaccharide distribution.

This study found that hemoglobin α is upregulated in epidermal keratinocytes after UV exposure and may function as an antioxidant, particularly for hair follicle stem cells.

This study reports two cases of trichoblastic neoplasms with histologic features suggesting they may be distinct, locally aggressive trichoblastic carcinomas separate from basal cell carcinoma.

This study in mice found that WWP2 facilitates odontoblast differentiation and dentin formation by targeting PTEN for degradation, thereby enhancing KLF5 activity, which may suggest its crucial role in dental development.

This study found that keratoacanthoma of the lip likely arises from outer root sheath cells, based on the presence of specific keratin markers and periodic acid-Schiff staining patterns.

Fibroblasts can be turned into melanocytes for potential skin treatments.

In this study, ob/ob mice were found to have a prolonged telogen hair cycle phase from 10 to 24 weeks, suggesting their potential as a model for studying telogen effluvium.

This case report describes a twenty-year-old woman misdiagnosed with a sebaceous cyst that was actually pilomatrixoma, a benign skin lesion from hair matrix cells, confirmed by histopathology after excision.

In this case study, a 51-year-old Japanese man was diagnosed with desmoplastic trichoepithelioma after histological examination of surgically excised facial plaques.

In this study, researchers identified exosomal miR-199a-3p as a key factor in the regulation of melanogenesis by dermal papilla cells, finding that it enhances melanocyte proliferation and melanin production, suggesting potential therapeutic targets for pigmentation disorders.

This study established that the Dct::CreERT2 mouse line is effective for targeting and studying adult melanocyte stem cells, contributing to the understanding of melanocyte biology and hair pigmentation.

This report presents four new cases of follicular porokeratosis, which exhibit distinct histological features where the cornoid lamella are confined to the follicular ostia.

This study suggests that immunostaining for Keratin 15 may be a useful tool for differentiating between basal cell carcinoma and trichoepithelioma.

This paper reviews keratoacanthoma as a tumor that resembles but rarely progresses to squamous cell carcinoma, detailing its stages, potential origins, and distinguishing features from other similar growths, without reporting new clinical results.

The study concluded that all parts of the normal human Meibomian gland ductal system show signs of early keratinisation, supporting the idea that these glands are akin to "hair follicles without a hair shaft.

This study found that EGF receptors are aberrantly regulated and persist in cholesteatoma epithelium, suggesting a hyperproliferative character compared to normal human skin.

This study found that Krox20 marks a diverse stem cell population in mouse hair follicles, which significantly contributes to the interfollicular epidermis and regulates epidermal homeostasis.

This study found that photobiomodulation via LED light at 630 nm and 810 nm increased proliferation and mineralization in osteoblast-like cells, with comparable effects between the two wavelengths.

This study found that the genes MYLK and CALD1 were expressed at lower levels in bladder cancer and osteosarcoma tissues compared to normal tissues, and their expression levels appeared to correlate with poorer survival outcomes, suggesting they may be important in disease progression and prognosis.

This preliminary study observed that melanoblasts are preserved in the white hair follicles of segmental vitiligo lesions.
