Figure 2.

Restoration of blood flow to surgically induced ischemic limbs. The data are expressed as the percentage of blood flow in the operated limb relative to the contralateral unoperated limb on the same day. Data were normalized to correct for preoperative differences in the two legs. The mean fluxes were determined using laser Doppler imaging for 7–10 mice in each group and were averaged. Error bars represent standard errors. (a) Nondiabetic mice. (b) Diabetic mice (serum glucose > 220 mg/dL). CD34⁺, injected with CD34⁺ cells; CD34^–, injected with CD34^– cells; buffer, injected with vehicle or not injected.
