Immunohistochemical staining of RIP3 on the injured side in the transverse sections obtained at different time points. The expression of RIP3 was not observed at 4 h (e–h); however, it started to increase at 24 h (i–l), in comparison to that observed in the sham group (a–d). The population of RIP3-expressing cells was obviously larger at 3 and 7 days (m–t) than at the other time points. Scale bars 100 μm (a–c, e–g, j–k, m–o, q–s, u–w), 20 μm (d, h, l, p, t, x). The schematic drawing illustrates the location of the micrographs (y)
