Abstract (original English)
Decellularized adipose tissue (DAT) has attracted much attention due to its wide range of sources and adipose regeneration capacity. However, the lipogenic efficiency of DAT is still controversial due to its unclear mechanism. To this point, it is crucial to clarify the mechanism of DAT in promoting adipose regeneration Objective: This study aims to explore the mechanism of DAT promoting adipose regeneration and survival mechanism of DAT transplantation in vivo. DAT preparation by repeated freeze-thaw, enzymatic digestion, and isopropanol degreasing. Histology, DAPI, immunohistochemistry, immunofluorescence and scanning electron microscopy confirmed the efficacy and reproducibility of these approaches. BM-MSCs, ADSCs and UCMSCs were cocultured with DAT for 14 days and then stained with oil red O. Adipogenic genes of three MSCs were detected by RT-PCR. DAT and adipose tissue were transplanted subcutaneously into the back of nude mice to observe medium and long-term morphological changes, vascularization, and lipid-forming efficiency. Mass spectrometry (MS)-based proteomic to analyze the adipogenic protein contents of DAT and adipose tissue. The DAT without any cellular components but with an abundance of collagen; neither DNA nor lipids were detected. Seeding experiments with MSCs indicated that the DAT provided an inductive microenvironment for adipogenesis, supporting the expr
