Objectives: 1. To understand that adipose stem cell exosome (ASCE) can be a paradigm shift in regenerative aesthetics & therapeutics
2. To find that ASCE can attenuate severe inflammation and promote skin barrier reconstruction in atopic dermatitis model
3. To know that ASCE can improve dupilumab facial redness (DFR) and acne scar
4. To know that ASCE can make scalp rejuvenation and hair loss prevention
Introduction: Exosomes, nano-sized extracellular vesicles, are the most important mediator for intercellular communication. For last years, the dual function of skin regeneration and anti-inflammation of ASCE has been well known from a number of research. These days, ASCEs are being developed as next generation regenerative therapeutics and aesthetics as well. From our various studies, it has been shown that ASCE can be an innovative biomaterial as regenerative therapeutics as well as regenerative aesthetics for treatment of atopic dermatitis, acne scar, facial redness, & scalp rejuvenation/hair loss.
Materials / method: Human adipose mesenchymal stem cell-derived exosomes (ASCE) and a specific formulation including ASCE were applied or treated for a variety of in vitro, in vivo, & clinical studies.
Results: 1. ASCE could reduce or modulate over-reactive inflammation in skin in atopic dermatitis model. The AD score was significantly improved and major proinflammatory cytokines including IL-4, IL-13, TLSP, & others were down-regulated.
2. ASCE could promote the de novo synthesis of ceramide and dihydroceramide, key lipid molecules in skin barrier formation, which led to the significant improvement of atopic dermatitis model.
3. When compared to PRP, ASCE and a specific formulation could successfully improve the results in terms of rejuvenating the scalp and reducing hair loss.
Conclusion: ASCE may serve as next generation technology with competitive advantages over conventional regenerative aesthetics or therapeutics, in terms of regeneration and anti-inflammation.
