Tissue integration of the scaffolds treated with platelet-rich plasma (PRP), plasma surface modification (PSM) and rat adipose-derived stem cells (rADSCs) at 6 and 12 weeks using H&E analysis. a H&E analysis. Scale bars refer to 400 μm. b Quantification of tissue integration analysis of the modified PU scaffolds after 3 months of subcutaneous implantation in a rodent model (n = 6). Note that the PM+ADSC and PM+ADSC+PRP scaffolds showed significantly greater tissue integration than all other scaffolds (p < 0.05). PU unmodified scaffolds, PRP platelet-rich plasma-modified scaffolds, PM argon-modified scaffold, ADSC rat adipose-derived stem cell-modified scaffolds. *p values < 0.05, **p < 0.01 and *** p < 0.001
