Low-dose acitretin helps nail psoriasis, stem cells may treat scarring alopecia, Chinese men have lower baldness rates, lateral foldplasty is good for ingrown toenails, hair diameter helps diagnose female baldness, childhood trauma linked to alopecia areata, certain hair-weaving leads to scalp conditions in African American women, and new methods for hair research and understanding hair and sweat gland development were introduced.

This review highlights the importance of using 3D scaffolds in vitro to support hair follicle regeneration, emphasizing how these structures help maintain cell function and mimic the natural environment, which is crucial for developing hair follicle organoids for transplantation.

This review discusses recent advancements in generating appendage-bearing skin organoids from pluripotent stem cells and their potential applications in dermatological research, but reports no new clinical results.

In this study, researchers investigated the impact of a bioactive peptide derived from amphibians on hair follicle regeneration in diabetic skin, focusing on its potential to enhance wound healing and reduce infection risk.

This chapter reviews therapies for skin and corneal regeneration and hair loss, discussing various treatments but presenting no new research findings.

This study found that CRABP1, Nestin, and Ephrin B2 are expressed in both the tumor stroma and invasive front of skin adnexal tumors and basal cell carcinomas.

The authors concluded that Lrig1-positive stem cells are essential for sebaceous gland formation in mice, as their ablation led to temporary sebaceous gland disappearance without affecting hair growth.

This study suggests that sweat glands may have an immune privilege similar to hair follicles, and disruptions in this could contribute to autoimmune skin diseases.

This study found that reduced cell cohesiveness in eccrine sweat gland outgrowths contributed to delayed wound healing in elderly skin compared to younger skin.

This study reports that human eccrine sweat gland cells are capable of forming a stratified epidermis, suggesting they may serve as an additional source of keratinocytes for skin repair.

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.

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

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 study demonstrated that cultured epidermal stem cells and skin-derived precursors can regenerate functional hair follicles and sebaceous glands in both mice and adult humans, suggesting potential for bioengineered skin substitutes.

Mesenchymal stiffness affects sweat gland cell development.

This study found that the GPR39 receptor plays a novel role in accelerating wound healing in mouse skin, although it is not essential for skin development or homeostasis.

This study developed a method to convert fibroblasts into sweat gland-like cells, suggesting potential for regenerating damaged skin and restoring sweat gland function.

This review discusses the reuse of molecular mechanisms involved in embryonic skin development for maintaining adult epidermal homeostasis and reports no new results.

This review discusses the identification and roles of different epidermal stem cell types in skin homeostasis and repair, and reports no new experimental findings.

This study found that while 3D spheroid culture preserved sweat gland cell-specific markers better than 2D culture, their growth and structural organization were suboptimal, highlighting the need for improved culture systems.

The researchers reported that minor salivary gland stem cells exhibit stem cell characteristics and respond to tobacco-derived carcinogens, implicating the transforming growth factor beta pathway in their maintenance.

This study demonstrates that Tp63-expressing epithelial stem cells from non-skin tissues can respond to skin morphogenetic signals and contribute to the formation of hair follicles, sebaceous glands, and epidermis.

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 chapter reviews the presence and roles of stem cells in various body systems, focusing on their lifelong function in animals and humans, and reports no new experimental findings.

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

This review explores the novel roles of white adipose tissue in tissue homeostasis and regeneration, emphasizing its impact on epithelial, muscle, and immune tissues, and reports no new clinical results.

This study describes a new method for isolating intact human eccrine glands from scalp follicular units, potentially advancing research on sweat gland physiology.

Tissue stiffness affects sweat gland development by guiding cell differentiation through specific signals.

This study suggests that heparan sulfate is crucial for regulating hair follicle formation, cycling, and gland morphogenesis, with its ablation leading to continuous hair growth and increased gland activity in mice.

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.
