This review suggests that the umbilical cord-derived mesenchymal stem cell secretome presents a promising approach for skin regeneration and wound healing due to its multiple therapeutic properties, highlighting its potential over traditional treatments for conditions like chronic wounds and alopecia.

This study found that ultraviolet radiation negatively affects hair follicle functions in human scalp skin, and caffeine application may provide some protective effects against this damage.

This study suggests that keratinocytes derived from hair follicles of patients with atopic dermatitis provide a useful model for investigating AD-related inflammation, as they showed greater expression changes of AD markers when stimulated with type 2 cytokines compared to those from healthy donors.

In this study, fibroblasts from long-term skin biopsy cultures retained their ability to reprogram into induced pluripotent stem cells after 16 months, despite undergoing transcriptional changes and decreased proliferation rates over successive generations.

This study found that hair follicle stem cells from hidradenitis suppurativa patients showed alterations in cell cycle regulation and DNA replication, potentially linking genetic predisposition to the skin inflammation characteristic of the disease.

This review discusses the potential of mesenchymal stem/stromal cells and their exosomes in promoting wound healing and skin regeneration, but reports no new experimental results.

Low-intensity ultrasound may help protect hair follicles from chemotherapy-induced hair loss.

This study found that human sweat glands contain unique stem cells with significant multilineage differentiation potential and self-renewal abilities, suggesting promising clinical applications due to easy biopsy access.

This study found that adipose-derived mesenchymal stromal cell secretome, particularly when preconditioned with IFNγ, significantly influences cell motility and anti-inflammatory responses, enhancing its potential as a regenerative therapy.

This study found that synthetic RNA and DNA trigger significant increases in certain chemokines in human keratinocytes, predominantly via NF-κB activation, without evidence of alternative splicing, suggesting other regulatory pathways may be involved.

This review examines existing scientific literature on African plants with anti-cancer properties and reports no new experimental results.

This study found that hMSC secretomes from umbilical cord Wharton's jelly had the most potent angiogenic effects, whereas those from adipose tissue demonstrated the weakest angiogenic potential.

This review discusses various stem cell types, methods of obtaining them, their applications, and the potential use of exosomes, but reports no new clinical results.
