This review discusses the classification and diagnosis of hair shaft disorders based on fragility and emphasizes preventive care due to the lack of specific treatments.

This case report describes a rare instance of Olmsted syndrome with hypotrichosis in a 5-year-old boy, noting mild improvement in symptoms following treatment with oral acitretin and other interventions.

This review discusses the potential of using human pluripotent stem cells to generate new hair follicles, though practical challenges remain before it can be applied for hair restoration.

This study identified epiprofin as a highly tissue-specific nuclear protein that promotes cell proliferation, mainly expressed in the developing teeth, hair follicles, and limbs of embryonic mice.

New mutations in the hairless gene may cause hair loss and affect bone development.

Injecting lentiviral vectors into early gestation mice effectively targets skin stem cells for potential gene therapy.

This review discusses autologous dermis-derived stem cells and their potential in regenerative medicine, summarizing current literature on their niches, characteristics, and applications, but it reports no new experimental results.

This study highlights the phenotypic variability in 5 patients with Woodhouse-Sakati syndrome carrying the c.436delC mutation, suggesting a broader range of clinical presentations than previously recognized.

This study found that manipulating Wnt/β-catenin signaling in embryonic mammary glands impacted their development, with high activity levels hindering branching and potentially redirecting cells toward hair follicle identity instead of mammary tissue.

This review of DAVID syndrome cases found that ACTH deficiency often preceded by sinus infections or alopecia is linked to specific NFKB2 gene mutations, highlighting the importance of early diagnosis to prevent complications.

This study found that local injections of fetal tissue mesenchymal stromal cells in mice significantly improved healing and hair follicle density after high-dose radiation-induced skin damage.

In a mouse model study, researchers found that mutations in Aire reduced alopecia areata frequency, while Notch4 mutations did not lead to the disease, likely due to proximity with a resistance gene.

This case series describes eight instances of autosomal recessive woolly hair in an Indian population over the past 12 years, detailing their clinical presentation, hair traits, and treatment response.

This case report presents a very rare instance of pilonidal sinus in the preauricular region, marking only the second known case documented in medical literature.

This article reviews the potential of adipose-derived and Wharton’s jelly stem cells in alopecia treatment but presents no new clinical findings, highlighting their potential benefits and limitations in regenerative medicine.

In this study, a specific retinoic acid receptor antagonist caused severe craniofacial anomalies in mouse fetuses when administered early in pregnancy, but not limb anomalies, highlighting developmental stage-specific roles of retinoic acid.

This review examines the regeneration capabilities of skin, oesophagus, and oral mucosa, highlighting the oral mucosa's unique scarless healing properties and the potential of cell therapy to improve scar reduction in wound healing.

Keratin patterns in hair follicles help understand hair growth and potential hair and nail disorders.

This study found that transplantation of autologous stromal vascular fraction cells increased skin thickness and improved regeneration when combined with mechanical stretching, without severe adverse events.

This review discusses vitamin D and calcium signaling roles in epidermal stem cell processes essential for wound healing but reports no new experimental results, emphasizing their potential interdependent regulatory mechanisms.

In this study, researchers found that while both hair follicles and skin dermis-derived neural crest stem cells are suitable for large-scale manufacturing, skin dermis cells grow faster and are easier to obtain.

This review discusses the interactions between immune cells and the skin epithelium and their impact on maintaining barrier function, emphasizing the potential to enhance epithelial barrier function in inflammatory diseases.

This review discusses current strategies and materials in tissue engineering for skin regeneration, emphasizing design approaches and suggesting directions for future research; it reports no new clinical findings.

This study successfully established Tsc2-deficient embryonic stem cells from Eker rats and found these cells have distinct gene expression compared to non-mutant cells, which could help identify new therapeutic targets for TSC-related pathogenesis.

This study found that the expression of the sonic hedgehog protein is involved in wound healing texture regeneration, inhibiting skin texture after embryonic day 14 and affecting keratinocyte migration and division.

This study reports differential gene expression in the leading edge and inner surface epithelial cells of murine eyelids, suggesting that distinct signaling pathways are active during embryonic eyelid closure.

This review discusses the roles of dermal white adipose tissue in skin functions and pathology, underscoring its antibacterial activity and potential anti-fibrotic role, but reports no new experimental results.

This review highlights exosomes as a promising treatment for skin damage from UV light, infrared radiation, burns, and disorders due to their anti-inflammatory properties, ability to induce macrophage polarization, and acceleration of skin repair and regeneration.

This source reviews current understanding of fibroblast lineage differentiation and its role in wound healing, highlighting the potential to reprogram adult cells for scar-free repair by emulating fetal-like regenerative states.

This review explores current knowledge on fibroblast lineage specification and its impact on scar-free wound healing, noting that early fetal skin fibroblasts support regeneration, while later developmental shifts lead to fibrosis, highlighting potential strategies to reprogram adult fibroblasts for regenerative repair.
