Fig. 4From: Argon plasma surface modification promotes the therapeutic angiogenesis and tissue formation of tissue-engineered scaffolds in vivo by adipose-derived stem cellsMasson’s trichrome staining at 6 and 12 weeks of subcutaneous implantation of the scaffolds treated with platelet-rich plasma (PRP), plasma surface modification (PSM) and rat adipose-derived stem cells (rADSCs). Note that the PM+ADSC and PM+ADSC+PRP scaffolds showed greater collagen staining than all other scaffolds over the 12 weeks (n = 6). Scale bars refer to 400 μm.
