This article reviews the role of adult stem cells in tissue homeostasis and wound repair, focusing on their regulation within the murine hair follicle's specialized niche, but it presents no new findings.

In this study, researchers found that microRNAs and specific target genes, such as MiR-195 and genes like CHP1, SMAD2, FZD6, and SIAH1, play significant roles in regulating hair follicle initiation in cashmere goats.

This study found that modulating BMP activity in transgenic mice affects the development and characteristics of several ectodermal organs, such as skin, hair, and claws, highlighting a stage-dependent influence on organogenesis.

This study identifies iRhom2 as a crucial regulator of hair follicle differentiation, showing that the iRhom2Uncv mutation leads to dysplasia and reduced TACE maturation, resulting in a hairless phenotype in mice.

This study found that extracts from Angelica gigas Nakai and Glycyrrhiza uralensis stimulated hair regrowth and follicle development in a shaving mouse model, suggesting potential for hair growth or hair loss prevention in humans.

This case report presented a 52-year-old man with cutaneous focal mucinosis, exhibiting rare follicular induction of the epidermis, underscoring the importance of recognizing this association in differential diagnoses.

This study found that the serine protease BSSP is strongly expressed in mouse skin during carcinogenesis and is upregulated independently of c-Fos and unaffected by glucocorticoids.

This study found that Hoxc13 gene expression, influenced by melatonin, was associated with hair follicle activity in Cashmere goats, with in vitro evidence suggesting effects on genes relevant to follicle development.

This study found that the mutant hairless rhino bald protein in mice interacts with the vitamin D receptor but cannot repress its transactivation and shows abnormal cellular localization.

This case report describes a giant pigmented tumor of the scalp in a 47-year-old woman and suggests a possible dual origin involving neural crest differentiation.

This study suggests that the MAEG protein may facilitate epithelial–mesenchymal interactions during hair follicle development by binding to RGD-binding integrins like α8β1.

In this study, subcutaneous injections of murine epidermal growth factor in marsupial pouch young inhibited the formation of hair follicles and associated structures, altering normal follicle development.

This study found that Hex gene expression patterns in chick embryo dorsal skin during feather bud development suggest a significant role in initiating feather morphogenesis.

This study observed that isoproterenol directs hair-follicle-associated pluripotent stem cells to differentiate into cardiac muscle cells in large numbers, forming tissue sheets of beating heart muscle cells in culture.

This case study reported transient localized hypertrichosis in a 26-year-old woman following cast removal from a forearm fracture, which resolved on its own after 5 months, suggesting that similar incidents of hair growth after trauma may have a benign and temporary course.

This notice provides information about JAMA Dermatology's website usage policy, and no research findings are reported.

This study found that the DNA methylation status of skin samples from cashmere goats was higher during the telogen stage compared to the anagen stage, identifying genes potentially important for hair follicle development and growth.

This study found that injecting highly purified monocyto-angiotropin into hare skin induced new blood vessel formation and significantly accelerated hair growth at the injection site compared to control areas.

In this case report, the researchers highlight a possible association between myotonic dystrophy type 1 and multiple tongue hemangiomas, and emphasize that patients with this condition can experience exacerbated respiratory muscle weakness and risk of respiratory failure even with epidural anesthesia.

This study found that a water-soluble peptide from chicken egg yolk, named Hair Growth Peptide, improved hair growth in mice and female pattern hair loss through increased IGF-1 and VEGF production.

This study found that JUNB enhances hair regeneration in mice by promoting dermal papilla cell proliferation through the Wnt signaling pathway, suggesting JUNB as a potential molecular target for improving cashmere quality and breeding in cashmere goats.

Senescent melanocytes in nevus skin boost hair growth.

This study found that the occipital scalp had significantly higher epidermal nerve fiber density than the frontoparietal scalp, which may explain increased sensitivity in some patients.

In this study, a possible case of Wolf’s isotopic response was observed, where a 72-year-old woman developed superficial basal cell carcinoma at a prior herpes zoster site on her scalp, possibly due to altered local immunity from the zoster episode.

This study concluded that myositis in the reported case was caused by T-cell large granular lymphocytic leukemia, not dermatomyositis.

This review discusses various extra facial esthetic indications of botulinum toxin, like neck rejuvenation and calf slimming, and reports no clinical results; essential tips for each indication are included.

This report describes two scalp lichen simplex chronicus cases with hair loss and intense itching, noting unique dermoscopic and histopathological features.

In this study, transiently activating the sonic hedgehog signaling pathway in chickens transformed reticulate scales on the feet into feathers comparable to body feathers, without ongoing treatment, suggesting this pathway affects the diversity of bird skin appendages.

This article describes a case of pilomatricoma in a 22-year-old male with successful surgical excision and no recurrence, highlighting its histopathological features and typical clinical presentation.

This study shows that differences in Hoxc gene expression in hair follicle mesenchyme along the body axis contribute to regional variations in mammalian hair growth.
