TLDR A special membrane with cell particles helps heal diabetic wounds faster.

The study demonstrated that human acellular amniotic membrane (hAAM) scaffolds incorporating exosomes from adipose-derived mesenchymal stem cells (ADSC-Exos) significantly promoted diabetic wound healing in mice. The hAAM-Exos combination improved wound healing by enhancing cell proliferation, migration, and angiogenesis, while reducing inflammation and improving collagen deposition. The hAAM-Exos group showed superior wound healing capabilities compared to control groups, with increased vessel density and collagen accumulation. Despite these benefits, regeneration of hair follicles and sebaceous glands was not observed by day 21. The study suggested potential for clinical applications, though further research was needed to understand the molecular mechanisms involved.

community If You Have DUPA, PLEASE READ THIS: Everyone Should Be Scalp Biopsied

in Research 830 upvotes 1 year ago

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

community Has anyone tried Exosomes from Musely or somewhere else?

in Hair Systems 9 upvotes 8 months ago

Exosomes from Musely are being discussed as a topical hair loss treatment containing ingredients like latanoprost, caffeine, cetirizine, melatonin, vitamin D3, vitamin E, and biotin. Users are curious about its effectiveness and potential side effects, noting it may take 4-6 months to see results.
