FIG. 2.

Distribution of VEGF levels in clonal populations of myoblasts expressing murine or human VEGF. Single myoblast clones expressing either mouse or human VEGF were isolated from the polyclonal populations and their VEGF expression in vitro was quantified by enzyme-linked immunosorbent assay (ELISA), showing that both populations had a similar distribution of VEGF expression levels in individual cells. White bars=murine VEGF (mV)-expressing myoblasts; black bars=human VEGF (hV)-expressing myoblasts.
