This study found that canine hair follicle stem cells are located in the isthmus/bulge region of the hair follicle, surrounded by telocytes.

This study found that dermal papilla-like tissues derived from canine adipose stem cells promoted new hair follicle formation and increased vascularization in athymic nude mice.

This study found that active androgens activate lipogenic differentiation in human sebocytes expressing a functional androgen receptor, influencing gene expression and lipid synthesis, while also increasing apoptotic cell population over time.

In this study, researchers presented a protocol for generating planar skin organoids from human induced pluripotent stem cells, which include hair follicles and other skin structures, offering a relevant in vitro model for investigating skin physiology, pathogen interactions, and drug responses.

This study found that topical transplantation of green fluorescent protein-labeled bone marrow mesenchymal stem cells significantly improved regeneration of deeper wounds, with increased blood vessel formation, compared to control in a rat model.

This review summarizes recent multidisciplinary advances in sebaceous gland research and highlights potential novel therapeutic strategies for skin diseases, but it reports no new clinical results.

In this study, nestin-expressing cells in the hair follicle bulge, marked by GFP in transgenic mice, were identified as progenitors of the hair follicle outer-root sheath.

This study identified a novel MTS24-positive murine keratinocyte population with increased colony-forming ability, suggesting these cells may serve as a new reservoir of proliferative progenitor or stem cells in hair follicles.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

Sericin hydrogels heal skin wounds well, regrowing hair and glands with less scarring.

This study describes a protocol for generating a fully functional 3D integumentary organ system from murine induced pluripotent stem cells, including the formation of hair follicles and sebaceous glands that function in vivo.

This study identified a novel skin site called the follicular epidermis that is prone to cancer, with unique Axin2+ stem cells regulating its homeostasis. The findings suggest current therapeutic approaches may need reconsideration due to new insights into obstruction mechanisms at this site.

In this study, mouse sebaceous glands were found to require nerves for growth during active hair cycles, suggesting a nerve-dependent sebaceous gland cycle coordinated with hair growth.

This review discusses the role of signaling networks in sebaceous gland development and disorders, highlighting recent insights from mouse models and cell line studies, but reports no new experimental results.

This study reports that sebaceous glands can regenerate after injury through stem cell plasticity, with hair-follicle-derived stem cells replacing sebaceous gland progenitors and playing a crucial role in the regeneration process, which is dependent on FGFR2 signaling and aided by hair growth induction.

This study suggests that the newly characterized sebocytic progenitor cells HSGC1 and HSGC2 from different skin sites may have proliferative and differentiating potential in response to DHT.

This study found that sebaceous glands in the skin are primarily renewed by their own stem cells during normal conditions, but after injury, they regenerate through stem cells from hair follicles, highlighting stem cell plasticity and regeneration capabilities.

This review examines the role of retinoic acid synthesis in hair follicles and sebaceous glands, focusing on its localization and function during normal and disease states, but reports no new results.

Researchers created a fully functional, bioengineered skin system with hair from stem cells that successfully integrated when transplanted into mice.

This study found that, in Japanese patients with androgenic alopecia, sebaceous glands exhibit increased multilobulation which may be significant in the condition's pathology.

In this study, researchers observed that human sebaceous glands can regenerate in a mouse model using transplanted human skin, potentially offering a tool to study sebaceous gland biology and regeneration.

This case report describes a 29-year-old Japanese man with follicular mucinosis, suggesting nestin-positive, multipotent hair follicle stem cells may be involved in reticular epithelial degeneration of the outer root sheath.

In this study, Lrig1-positive stem cells in mouse hair follicles were found to be essential for sebaceous gland formation and maintenance, with their depletion causing a temporary loss of these glands and changes in cellular differentiation.

This workshop overview concluded that follicular epithelial stem cells are multipotent and located in the bulge region of hair follicles, contributing to hair, epidermis, and sebaceous gland formation.

This study found that Lrig1-positive cells in mouse epidermis are a previously unidentified source of adult interfollicular epidermal stem cells, which can contribute to sebaceous gland and epidermal lineage formation.

This article discusses the factors contributing to acne and reports no new findings, focusing on the role of sebaceous lipids and associated processes.

This study demonstrated that fibrin hydrogels support skin-derived precursors in hair follicle neogenesis in mice, with new hair growth and regeneration of blood vessels and sebaceous glands observed.

This review revisits mechanisms underlying acne lesion formation and suggests that preventing comedone development requires controlling critical factors in the pilosebaceous follicle before acne involvement.

This review summarizes the roles of matricellular proteins in skin stem cell niches, highlighting their contribution to stem cell fate, self-renewal, and potential implications for wound healing and aging.

This research discusses how epithelial stem cells in the skin maintain normal homeostasis, contribute to wound repair, and highlights the importance of these processes, as defects can lead to skin diseases including cancers, but provides no new experimental results.
