Fig. 6. Restoration of the blood flow in surgically induced ischemia in diabetic mouse hindlimbs. The data are expressed as the percentage of blood flow in the operated limb relative to the contralateral unoperated limb from the same animal. Fluxes were measured using a scanning laser Doppler and means of between three and five readings were calculated for each animal at each time point. Averages of means for 4-16 animals were plotted as a function of time. Error bars represent standard error. *, Unsorted cells significantly different to fibroblast-injected and control animals by one-way Anova (P<0.05); {ddagger}, unsorted and progenitor cells significantly different to fibroblast-injected and control animals by one-way Anova (P<0.05); ¥, unsorted cells, progenitor cells and TA cells significantly different from fibroblast-injected and control animals by one-way Anova (P<0.05). The linear regression of the flow from progenitor-cell-injected animals was also significantly different from the control animals by one-way Anova (P<0.05).
