In this study, researchers found that the number of dermal papilla cells in hair follicles determines hair size and shape in mice, suggesting potential avenues for addressing hair loss.

This case report describes a young man diagnosed with encephalocraniocutaneous lipomatosis who had unique bilateral optic disc colobomas, a previously unreported association with this syndrome.

PCFCL may have unrecognized subtypes and needs more research.

This study found that tight junctions extend to the most superficial layer of the stratum granulosum in human skin, challenging previous claims of their limited presence in the epidermis.

This study found that carbonic anhydrase II was significantly upregulated in human keratinocytes when treated with toll-like receptor 3 agonist and Th2 cytokines, suggesting its potential role in inflammatory skin conditions.

This report documents a novel alanine to valine substitution in the GJB2 gene in a Japanese girl with severe keratitis–ichthyosis–deafness syndrome, suggesting a potential link to her severe recurrent infections and immunodeficiency.

This study found that nail and hair changes were predominantly observed in patients with stage 5D chronic kidney disease, with the most common changes being half and half nails and sparse scalp hair.

Allergic contact dermatitis may promote hair growth by activating hair follicle stem cells.

This study suggests that new cells are incorporated into the dermal papilla during the early anagen phase of the hair cycle, which may influence hair growth consistency and follicle size changes.

This abstract reviews hereditary vitamin D-resistant rickets, a rare genetic condition causing severe early childhood rickets, and reports no new results; effective treatment typically requires high doses of calcium to address hypocalcemia and secondary hyperparathyroidism.

In this study, researchers discovered that HEY2+ dermal papilla cells exhibit stemness and contribute to dermal regeneration during wound healing, as shown by the expression of a reporter gene in regenerated dermal cells of tamoxifen-induced transgenic mice.

A single medium, PRIME AIRLIFT, supports better human hair follicle formation in grafts.

This study found that microencapsulated dermal papillae cells induced hair follicle regeneration in rat ears, differing from normal follicles in configuration, size, number, and differentiation degree.

This study reports the draft genome sequence of the endangered Indus River dolphin and suggests potential genetic adaptations to freshwater environments, including specialized skin features and immune adaptations, while also highlighting historical and human-induced factors contributing to its low genetic diversity.

This study successfully optimized a culture strategy for dermal papilla cells and established an immortalized cell strain, iDP6, which closely resembles primary DP cells in key characteristics.

In this study, researchers found that disrupting desmoglein 3 signaling in a mouse model of pemphigus vulgaris activates normally quiescent hair follicle stem cells, compromising their multipotency but prompting a regenerative response that restores stem cell function and structures.

This study found that multiple eccrine duct dilation is highly specific for diagnosing cicatricial alopecia and may indicate scarring processes, aiding in accurate differential diagnosis from noncicatricial alopecias.

Human epidermal stem cells divide faster than previously thought.

This study found that Wnt and Hedgehog signaling coordinate to create sharp cell type boundaries during hair follicle development by synchronizing cell cycle exit and differentiation.

This case report presents a rare subtype of hypomyelinating leukodystrophy linked to a PYCR2 gene mutation, emphasizing exome sequencing's value in diagnosing undiagnosed childhood HLDs with atypical symptoms.

A peptide in shampoo can promote hair growth and improve hair condition.

This review examines the various functions of vitamin D and its receptor in regulating skin processes, highlighting their role in cell differentiation, immunity, and tumor suppression, but reports no new clinical results.

This study found that cedrol-loaded dissolvable microneedles efficiently delivered cedrol to the deep dermis, effectively promoting hair growth in C57BL/6 mice, suggesting a promising strategy for treating hair loss.

This review discusses the development and role of corneodesmosin in skin and hair follicle integrity, highlighting findings from mouse models and its connection to genetic diseases, with no new experimental results included.

This review identifies genetic mutations associated with congenital hair loss disorders in Japanese populations, particularly highlighting common LIPH gene mutations linked to woolly hair/hypotrichosis, and reports no new clinical results.

In this study, researchers identified slow cycling label retaining cells in nail and sweat gland appendages, showing stem cell characteristics similar to hair follicles but with distinct features.

This review discusses the regulation and function of vitamin D and its receptor in skin cells, highlighting their roles in processes such as proliferation inhibition, differentiation, and innate immunity, but reports no new results.
