Fibrin Gel as an Injectable Biodegradable Scaffold and Cell Carrier for Tissue Engineering

Figure 4

H&E staining of histological tissue section. Myocardium wall became thin in the infarction site (arrows in (a)). No vessels and viable cells were observed in infarction site (b). After eight weeks, the treatment of cell transplantation with fibrin gel (c) demonstrated extensive tissue regeneration when compared with cell transplantation without fibrin gel (d). Scale bar indicates 2 mm (a) and 100 μm ((b), (c), and (d)) [47].
