Different types of alopecia in children require specific diagnoses and treatments.

This article reviews therapeutic advances published between December 1986 and December 1987 but reports no new research findings; readers are advised to consult the original articles before considering new therapies.

This research highlights that engineered mice lacking the vitamin D receptor show multiple health issues similar to human vitamin D deficiency, underscoring the widespread impacts of the vitamin D endocrine system.

Lgr5 is a marker for active, long-lasting stem cells in mouse hair follicles.

Hair follicles can regrow in wounded adult mouse skin using a process like embryo development.

This review explores how adult skin epithelia preserve stem cell populations for hair follicle regeneration and wound healing, but reports no new experimental results.

Different types of long-lasting stem cells are responsible for the growth and upkeep of the mammary gland.

This review discusses the role of androgens in the progression of cardiovascular disease and explores novel therapeutic targets without reporting new clinical results.

This study found that differentiated airway epithelial cells can revert into functional stem cells in vivo, suggesting a more general role for this dedifferentiation process in tissue regeneration in higher vertebrates.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

This review discusses the role of Lgr5 as a marker for identifying adult stem cells, particularly in the intestine and hair follicles, and reports no clinical results.

This study found that the circadian clock regulates the activation state of murine epidermal stem cells, affecting tissue homeostasis and susceptibility to tumorigenesis when disrupted.

This study identified Lgr5 and Lgr6 as receptors expressed by small populations of stem cells in various adult organs, with Lgr5+ve cells forming long-lived organoids in certain mouse models.

This study reveals that overexpression of Wnt3 in transgenic mouse skin leads to a short-hair phenotype and cyclical balding due to structural defects in hair shafts, highlighting a role for WNT signaling in hair growth regulation.

This review discusses the role of stem cell progeny as integral components of stem cell niches, offering feedback that may influence different stem cell systems' microenvironments, but it presents no new research findings.

This study demonstrated that stress-derived neurosteroid THDOC shifts from inhibiting to activating the HPA axis under stress, presenting potential therapeutic targets for stress-related disorders.

This study found that Wnt1/βcatenin signaling plays a crucial role in activating the epicardium and cardiac fibroblasts, which supports cardiac repair following acute ischemic injury.

This article provides an overview of how dermoscopy can aid in the noninvasive diagnosis of various general dermatological disorders, grouped by clinical presentation, but reports no new clinical results.

This study found that adipocytes play a crucial role in skin wound healing by facilitating fibroblast recruitment and dermal reconstruction during the healing process.

This study found that many effects previously thought to be caused by circadian rhythm disruption in Bmal1 knockout mice are actually due to BMAL1's properties unrelated to its clock function.

This study found that removing PPARγ specifically from mouse adipose tissue led to severe fat loss, insulin resistance, diabetes, and associated metabolic abnormalities.

This study found that glycolytic metabolism and lactate production are crucial for hair follicle stem cell activation, and manipulating these processes can stimulate the hair cycle.

This study identifies a bipotent stem cell in adult hair follicles that self-renews and contributes to dermal sheath and papilla cell populations, potentially aiding hair regrowth after injury, disease, or aging.

This study found that loss of Apc due to K14-cre-mediated gene recombination in mice led to aberrant growth in ectodermally derived squamous epithelia, implicating its critical role in specifying epithelial cell fates during embryonic development.

This study found that adipose-derived mesenchymal stem cells produced more anti-inflammatory and pro-angiogenic cytokines on electrospun scaffolds, which enhanced wound healing and macrophage activity in a rat model.

This study suggests that apoE4 may contribute to cognitive decline by reducing androgen receptor levels in the brain, but androgen treatment improved memory deficits in female mice expressing human apoE4.

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 review of interventions for alopecia areata found no significant treatment benefits for hair growth compared to placebo, indicating a need for larger, well-conducted studies.

This study found that hypertrophic chondrocytes at the fracture callus border may convert to osteoblasts, influenced by vasculature and pluripotency gene expression.
