Bars represent mean striatal cell viability in hemopexin WT and KO mice, 8 days after striatal collagenase injection (mean ± S.E.M., n= 8/condition), 9 days after autologous blood injection (14/condition), or 2 days after striatal hemin injection (5/condition), as assessed by MTT reduction to formazan. Control mice were injected with artificial CSF solution only. MTT reduction is expressed as a percentage of that in the hemisphere contralateral to the injection site. The CSF group consisted of four KO and four WT mice, which had similar values. *P<0.05, **P < 0.01 versus ratio in KO mice, Bonferroni multiple comparisons test.
