This study found that CD99 is strongly expressed in the basal cells and hair follicles of normal adult and developing fetal skin, with expression patterns becoming similar after 20 weeks of gestation.

This study found that a nutritional intervention in dogs led to changes in skin microbiome and immune-related gene expression, with reduced levels of certain fungal pathogens and a potential alleviation of atopic dermatitis symptoms.

This study demonstrated that biochemical analysis of proteins from fetal skin biopsies is feasible, potentially enhancing prenatal diagnostic capabilities for protein-related disorders.

Fetuin-A helps wounds heal without scars by promoting cell movement.

This article explores the use of monoclonal antibodies to study the presence and distribution patterns of melanocytes in developing human skin, but reports no new clinical results.

This study developed a new melanocyte cultivation medium without chemical mitogens, melanogenesis enhancers, or bovine products, demonstrating successful proliferation and melanotic differentiation of human melanocytes from hair follicles.

This study found that in fetal skin development, both α- and β-catenins showed similar expression patterns, indicating their related roles in the development of the epidermis and skin appendages.

This study found that a serum-free DMEM-F12 medium with 45% oxygen best supports in vitro development and differentiation of human fetal skin, closely mimicking the in vivo state.

This study found that cutaneous stem cells in the basal layer of fetal human skin contribute to the development of the epidermis and hair follicles, with specific marker expressions during different stages of skin development.

This study found that adhesion molecules, specifically integrins and cadherins, are crucial for the down growth and proliferation of hair follicles in human embryos and fetuses.

This article reviews the role of epithelial-mesenchymal interactions in hair follicle development and discusses the challenges of understanding the signals that regulate this complex process; it reports no new results.

This review discusses the scalp and follicular microbiome's potential role in hair diseases and the emerging interest in microbiome-targeted therapies, but reports no new clinical findings.

Vitamin D3 affects cell differentiation in specific skin areas.

This study describes a protocol for generating hair-bearing skin organoids from human pluripotent stem cells, achieving full complexity resembling fetal skin tissue by day 130 in vitro.

This study shows that keratin 2e exhibits distinct temporal and regional expression patterns in fetal epidermis, suggesting different regulatory and functional roles from other epidermal keratins.

This study found that activating the erbB-2 oncogene in transgenic mice led to severe skin abnormalities and fatal defects, indicating erbB-2's significant role in skin and hair follicle development.

This study suggests that any baldness, particularly moderate balding, is associated with a higher risk of fatal prostate cancer in men, supporting a possible link between hair loss and prostate cancer mechanisms.

Stress during pregnancy can thin fetal skin.

This study found that cortisol and corticosterone led to thinning of the epidermis and hair follicle regression in fetal mouse skin, while testosterone promoted differentiation and sebaceous gland development.

In this study, Dsc 1 was highly expressed in certain layers of fetal epidermis and hair follicle but not in basal cells or oral mucosa, indicating its potential role in maintaining epithelial integrity.

This study found that STAT3 signaling is essential for initiating the hair growth phase but not involved in hair follicle development during the fetal period.

This review discusses the development of human skin with a focus on desmosomes, noting the challenges of translating animal model findings to humans due to species differences and limited human sample access.

In this study, inactivating the TAF4 subunit of transcription factor TFIID in mouse epidermis disrupted gene expression linked to skin and hair function, and increased tumor risk.

The document concludes that the exact way alcohol causes harm to fetal development is unknown, but it significantly affects nutrient transport to the fetus and a safe level of alcohol during pregnancy is not determined.

Skin changes throughout life, from development before birth to aging effects like wrinkles, influenced by both genetics and environment.

This study suggests that programmed cell death plays a crucial role in shaping the structure of the human epidermis and its appendages during development.

This study found that basal cell epithelioma resembles fetal primary epithelial germ based on specific cellular characteristics.

The document concluded that stem cells are crucial for skin repair, regeneration, and may help in developing advanced skin substitutes.

This study describes the stages of hair follicle development and foetal pelage growth in southern elephant seals, highlighting the formation and shedding processes of the first and subsequent hair generations.
