This review highlights the significance of animal fibers, examining the molecular mechanisms influencing hair follicle development and their impact on fiber quality and quantity, with a focus on studies involving Angora and cashmere goats.

This review discusses the various uses of retinoids, derived from vitamin A, in cosmetic and dermatological treatments for conditions like acne, psoriasis, and skin aging. The authors emphasize retinoids' limited use due to their susceptibility to degradation and safety concerns, particularly with retinoic acid.

This review traces the historical understanding and treatment of acne across ancient Egyptian, Greek, and Roman civilizations, but provides no new clinical findings.

This review summarizes the roles of bone morphogenetic proteins in the development and regulation of normal and diseased skin, but it does not provide new clinical results.

This study reveals that β-catenin and retinoic acid are key regulators in the gene networks controlling the fate of skin appendages, such as scales and feathers.

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 article analyzes the role of the WNT signaling pathway in skin development, wound healing, and mechanical stretching, emphasizing its importance in understanding and potentially advancing treatments for skin-related diseases.

In this study, BLIMP1 was found to function in terminally differentiated epidermal cells to maintain homeostasis, rather than defining a sebocyte progenitor population.

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.

In this study, researchers found that YAP and TAZ, when localized in the nucleus of basal layer cells, are crucial for skin regeneration and hair growth, with their loss leading to slower cell proliferation, hair loss, and impaired wound healing in mice.

This study found that Notch signalling promotes differentiation of epidermal cells and acts as a tumour suppressor in the skin by interacting with various pathways and mechanisms.

This review discusses advances in understanding mammalian stem cell niches, particularly in bone marrow, tooth, and hair follicle, and highlights the potential for developing therapies targeting these niches for tissue repair.

This review discusses the role of jumonji family proteins in chromatin regulation and development, highlighting their involvement in transcriptional repression and histone demethylation, but reports no new experimental findings.

This review discusses epidermal stem cell diversity, revealing previously unrecognized differences in stem cell populations, but reports no new experimental results; it highlights the need for further exploration of stem cell interactions and quiescence.

This study found that hair follicle stem cells initially contribute to wound re-epithelialization, but long-lasting epidermal cells are primarily derived from a stem cell population in the isthmus portion of hair follicles.

This review discusses the conserved molecular mechanisms controlling hair follicle development and cycling and suggests they may also apply to other ectodermal derivatives, like teeth and feathers, but it reports no new results.

This review discusses the hair follicle cycle's complex regulation and highlights the potential for targeting catagen control in future therapies without presenting new experimental data.

This review discusses Wnt signaling pathways in skin development and stem cell regulation, highlighting potential interactions with other pathways but reports no new findings.

This study reports the successful differentiation of mouse induced pluripotent stem cells into keratinocytes that can regenerate skin and its structures in an in vivo environment.

This review discusses the influence of oestrogens on various skin components and highlights their modulatory roles and receptor pathways, but it reports no new clinical results.

This study found that overexpression of the mineralocorticoid receptor in a mouse model led to premature epidermal barrier development, keratinocyte apoptosis, and postnatal alopecia, indicating new roles for MR signaling in skin physiology.

This study found that daily consumption of soft drinks significantly increases the risk of moderate-to-severe acne in adolescents, particularly if sugar intake from these drinks exceeds 100 grams per day.

This article reviews the generation of complex integument patterns through genetic, chemical, and environmental influences, with applications in tissue engineering, but reports no new experimental results.

In this study, researchers differentiated induced pluripotent stem cells into cells with dermal papilla-like properties, demonstrating their potential role in hair follicle bioengineering and drug testing for hair growth.

This discussion proposes a model to incorporate patients with hormone-resistant prostate cancer into the existing framework by redefining hormone resistance and exploring new therapeutic approaches.

This review examines how fibroblasts contribute to regeneration in various organs and explores the potential of reverting adult fibroblasts to a fetal-like state for regenerative therapies, but reports no new empirical findings.

This study suggests that Keratin 15 expression in stratified epithelia may be regulated by two distinct mechanisms involving PKC/AP-1 pathway for differentiation and FOXM1 for basal cells, challenging its reliability as a sole stem cell marker.

In this study, epidermal Notch activation increased jagged 1 expression, leading to skin changes like thickening and blistering, with these effects inhibited when jagged 1 was absent.

Acne is significantly influenced by genetics, and understanding its genetic basis could lead to better, targeted treatments.

This review discusses the regulation and dynamics of the Wnt/β-catenin signaling pathway in development, pluripotency, and cancer, highlighting potential mechanisms and future research directions, but reports no new results.
