Different types of stem cells and their environments are key to skin repair and maintenance.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

This study found that hair follicle and interfollicular epidermis stem cells contribute differently to skin regeneration, with their persistence influenced by factors like spatial constraints and competition moderated by Notch suppression.

In this study, researchers found that eccrine sweat glands in human scalp skin are morphologically integrated into the pilosebaceous unit, suggesting they form a common homeostatic tissue environment with adjacent structures.

This study found that human hair follicle dermal cells, specifically dermal sheath cells, can serve as an alternative and potentially superior cell source for constructing the dermal component of bioengineered skin in both in vitro and in vivo settings.

This chapter discusses the skin stem cell niche as a complex ecosystem and highlights the diverse components and interactions that influence stem cell function, but it reports no new experimental results.

This study describes a method inspired by hair transplantation techniques to efficiently isolate eccrine sweat glands from human scalp hair grafts, potentially facilitating further research into their function.

This article reviews advanced strategies for enhancing drug delivery to cutaneous stem cells to improve treatment for skin conditions and reports no new experimental findings.

This study used a mouse model to reveal that S100A4-positive cells, specifically fibroblasts and immune cells, play a crucial role in nipple development, essential for successful lactation, despite no issues with mammary morphology or milk production.

This study suggests that hair follicle dermal stem/progenitor cells play a key role in both hair regeneration and skin wound healing, with potential implications for preventing hair follicle miniaturization linked to aging or alopecia.

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 review explores the mechanisms of adult stem cell self-renewal, using skin as a model, and reports no new results but raises important unanswered questions in the field.

This review discusses the embryonic origins and characteristics of various stem cell populations in the skin, but it provides no new experimental results.

This study provides evidence that human sweat gland myoepithelial cells contain stem cells capable of self-renewal and differentiating into sweat gland luminal cells.

This review highlights surprising similarities between hair follicles and antler units, suggesting that a comparative study of their biology could benefit understanding in both areas without presenting new empirical findings.

This study created a detailed spatial atlas of healthy human skin and basal cell carcinoma, revealing a potential hair follicle origin for basal cell carcinoma and expansion of certain mesenchymal cell populations.

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 found that multiple eccrine duct dilation is highly specific for diagnosing cicatricial alopecia and may indicate scarring processes, aiding in accurate differential diagnosis from noncicatricial alopecias.

This review discusses the structure and regenerative potential of hair follicles, highlighting their role in wound healing, stem cell populations, and keratin-based biomaterials, but it reports no new clinical results.

This review discusses the role of keratins in epithelial cell stress protection and cancer, highlighting their potential as multifunctional regulators and diagnostic markers, without presenting new research findings.

In this study, terbinafine reached high concentrations in stratum corneum and sebum after oral administration, with drug levels remaining above fungicidal concentrations for over three weeks.

This review discusses the presence of the StAR protein in 17 non-classical steroidogenic tissues, suggesting that advanced detection methods are needed for a complete understanding of its functions in these tissues.

The report suggests a possible link between hair loss and hidden scalp tumors but states more evidence is needed to confirm this.

Hormones significantly affect skin health, with vitamin D playing a key role.

This article reviews the potential role of prolactin as a neuroendocrine modulator in skin biology and pathology, discussing its relevance for conditions such as psoriasis and hair growth, but reports no new clinical findings.

This study observed that in primary extramammary Paget disease, carcinoma commonly spreads to significant depths along hair follicles and eccrine ducts, with a maximal depth of 3.6 mm.

This review elaborates on the skin side effects of chemotherapy and emphasizes identifying and managing both common and life-threatening skin reactions, without presenting new clinical findings.

This review discusses the early phases of melanomagenesis and the factors influencing melanoma cell variability and reports no new clinical results.

This review systematically analyzed literature to differentiate desmoplastic trichoepitheliomas from other cutaneous tumors based on clinical, histopathological, and immunohistochemical features but reports no new clinical results.

Hidradenitis Suppurativa is a chronic skin condition best treated early with surgery for better outcomes and less recurrence.
