Figure 2. Histological assessment.

Figure 2

Histological assessment of polymer and saline injections 7 weeks after MI. Representative slides stained with H&E: (A) PEG hydrogel (G′ = 0.5 kPa) injected in infarct region and (B) saline injected in infarct region. (C) Infarct wall thickness at 7 weeks post-MI. Wall thinning was prevented in the PEG injected group compared to the control. (*p<0.01, PEG: n = 7, saline: n = 8 ) Photomicrographs are taken at 10Х and scale bars are 1 mm. PEG area outlined with dotted line and demarcated by an asterisk (*).
