In this review, the authors summarize recent findings on dermal white adipose tissue (dWAT), highlighting its crucial role in the hair follicle microenvironment by regulating inflammation and immune responses, thus influencing hair regeneration.

Blocking DPP4 can help prevent fat loss and skin fibrosis.

This study found that an acellular dermal matrix derived from tilapia skin significantly accelerated wound healing and improved tissue regeneration quality in mouse and pig models compared to a commercial porcine-derived matrix, suggesting its potential as a safe, cost-effective bioscaffold for skin repair.

This study found that while niche architecture optimizes organ efficiency during hair follicle growth, it is not essential for the function of stem cell-derived tissues.

This study observed that a novel extracellular matrix hydrogel made from human fibroblast-derived matrix improved wound healing in animal models, showing significant effects such as hair follicle formation, reduced inflammation, enhanced pro-healing growth factor levels, and interaction with macrophages, compared to traditional collagen hydrogels.

This review evaluates the use of platelet-rich plasma in dermatology, highlighting favorable outcomes in several areas, especially androgenetic alopecia, despite a lack of large randomized controlled trials and consistency in protocols.

This review examines the current evidence for platelet-rich plasma in dermatology, finding favorable outcomes particularly for androgenetic alopecia, but highlights the need for more rigorous clinical trials and standardized protocols.

This review discusses the role of exosomes in medical aesthetics, focusing on their mechanisms, production, and preservation, but reports no new clinical results and highlights barriers to their widespread application.

This study reviews the role of exosomes in regenerative aesthetics, highlighting their potential in treating conditions like photoaging and wound healing through mechanisms like matrix remodeling and immunomodulation, while also noting advancements in exosome isolation techniques and regulatory considerations.

This study found that in stretch-mediated tissue expansion, fibroblasts adopt an embryonic-like, low-collagen state that enhances epidermal stem cell renewal, supporting coordinated skin expansion crucial for reconstructive surgeries.

This study demonstrated that CD19-CAR T cell therapy may promote structural regeneration in the skin of systemic sclerosis patients, as evidenced by histological improvements and fibroblast population changes, suggesting its potential for tissue remodeling in fibrotic diseases.
