Figure 1 Capillary formation at the anteroseptum and anterior wall. Number 1 represents the bone marrow mononuclear cell (BMMNC) subset; number 2 represents the bone marrow stromal cell (BMSC) subset; and number 3 represents the control group (magnification x200). The top row (1a, 2a, 3a) shows the findings of the anteroseptum (nontransplanted infarct area), and bottom row (1b, 2b, 3b) shows the findings of the anterior wall (transplanted infarct area). In the BMMNC and BMSC subsets, the anterior wall (1b, 2b) contained more capillaries than the anteroseptum (1a, 2a). In contrast, in the control group, both the anteroseptum (3a) and anterior wall (3b) contained very few capillaries.
