Schematic illustration of procedure of pDA (polydopamine)-assisted immobilization of Plt (platelet) on GC (gelatin cryogel) scaffold for guiding de novo adipose tissue regeneration: (a) immobilizing process of pDA and Plt on GC; (b) composite of pDA/GC/Plt and the chamber were anchored on the fat pad directly without traditional flap-dissection approach; (c) intraoperative view upon the dissection-free procedure; (d) regenerated adipose tissue exhibited typical lobular fat tissue structure including extensive vascularization and mature adipocytes; (e) GC acted as a bioreactor for adipose progenitor cell migration, proliferation, differentiation, and regeneration of adipose tissue.
