Analysis of cell death. A, B Apoptotic cell labeled using the TUNEL technique (red); note the condensed chromatin (arrowhead) labeled with DAPI (blue). C Chart showing the density of apoptotic cells in untreated, transplanted, and sham-operated PCD animals; note how sham-operated animals present a greater density of apoptotic cells, as well as the protective effect achieved by transplanting IMCs. Data are expressed as mean ± SEM. *p < 0.05. Scale bar: 25 μm
