RIPK3 and Stroke: Ripk3 and Mlkl in the ipsilateral hemisphere followed the same expression pattern: they were significantly increased by stroke (P < 0.01 for Ripk3 and P < 0.001 for Mlkl) and reduced by the injection of proliferation-supporting medium (significant for Mlkl P < 0.01), but not by NSC transplantation (Figure 2B and 2C).
