This study found that FZD2 is crucial for hair follicle formation and postnatal growth in mice and has a novel role in regulating early epidermal development, including stratification and cornification.

This review examines the diversity and role of stem cells in the adult dermis, noting a lack of precise understanding about their hierarchy and relationship to dermal fibroblast subpopulations, and reports no new results.

This paper reviews the differential diagnoses and diagnostic tests to distinguish alopecia areata from other types of hair loss, without providing new clinical findings.

This study suggests that targeting the increased expression of SIX1 in systemic sclerosis may be a viable strategy for addressing dermal fibrosis.

In a keratinocyte-specific knockout mouse model, this study found that deleting GRK2 disrupted hair follicle homeostasis, causing cyst-like structures, abnormal growth patterns, and eventual hair loss, suggesting potential links to immune-mediated alopecias.

This study reviews the embryological origins, anatomical and histological structure, and key functions of the skin, emphasizing its protective, sensory, and regulatory roles, as well as the social and psychological impacts of post-lesion changes.

This research presents a comprehensive workflow for producing EMA-compliant autologous keratinocyte-based therapies for wound healing and explores miRNA-mediated regulations in human keratinocytes and adipose-derived mesenchymal stem cells.

This study identifies key transcriptomic features and a necessary dermal niche for eccrine gland development, advancing potential regenerative approaches for these vital skin appendages.

This review discusses the roles and characteristics of skin stem cells, their niches, and signaling pathways in skin maintenance, aging, and cancer, highlighting their potential in therapeutic applications but presenting no new clinical findings.

This chapter reviews the skin's structure and its clinical relevance, highlighting connective tissue diseases and the potential for novel treatments like protein, cell, or stem cell transfer, but reports no new findings.

This study found that human hair follicles can be used to generate induced pluripotent stem cells, which can then efficiently differentiate back into keratinocytes.

This article reviews the role of stromal stem cells in mammalian wound repair, suggesting they may perform functions similar to blastemal cells in simpler organisms, but reports no new experimental results.

This review examines how mesenchymal stem cells and their derivatives may enhance skin regeneration and rejuvenation, but it reports no new clinical results; the authors suggest iPSC-derived MSCs hold promise for future therapies.

This review discusses circadian clock regulation in stem cells and its role in processes like neurogenesis, but reports no new results; the authors emphasize its significance in stem cell function across various tissues.

This study demonstrates that canonical Wnt signaling is crucial for maintaining thymic epithelial microenvironments in postnatal thymus, possibly by affecting TEC progenitor cells.

This study suggests that inactivation of β-catenin is necessary for chick retina regeneration, as it allows cells to enter the cell cycle during injury and promotes regeneration without needing FGF2.

This article discusses melanocyte development from neural crest cells and reports no new experimental results; the authors suggest a broader range of functions for melanocytes than previously recognized.

This review discusses the complex role of Runx family genes in regulating stem cells in blood and skin tissues and reports no new experimental results.

This study found that Ift20 is essential for hair follicle stem cell identity and hair regrowth, and it regulates keratinocyte migration during wound healing through focal adhesion integrin recycling, independently of ciliogenesis.

This study found that the absence of Hif-p4h-2 in specific mouse skin cells disrupted hair follicle development, leading to hair loss due to irregular keratin formation and pathway signaling.

This chapter classifies various benign skin tumors and discusses their characteristics, treatment indications, and potential for recurrence, but reports no new clinical findings.

This article reviews current strategies and advancements in regenerating skin appendages and sensory nerves in tissue-engineered skin, highlighting the challenge of restoring skin sensations like pain, temperature, and touch to improve patients’ quality of life.

Amenorrhea is relatively rare and initial testing should check FSH, TSH, and prolactin levels.

Hair growth dysfunction involves various conditions with limited treatment options.

This review discusses the mechanisms behind hair patterning during mouse embryonic development and reports no new experimental findings.

This review discusses cornea-specific keratin expression patterns in human and mouse development and reports no new experimental results; it highlights the need for investigating keratin mutations' role in pathology.

This study examined the formation of acquired curved hair and found that the fusion of hair matrix cells during follicle regeneration contributes to asymmetric follicle shapes and curved hair, potentially linked to changes in type IV collagen and protein expression levels.

This study showed that a 2-kilobase upstream region of the mouse keratin 17 gene enables targeted GFP expression in major epithelial appendages of transgenic mice, indicating sonic hedgehog's involvement in its regulation.

This study found that human induced pluripotent stem cells differentiated precisely to express certain markers during a specific window could enable successful hair follicle generation when transplanted.
