Figure 3 Myoblast in fibrin glue 24 h after injection. (A) 4',6-diamidino-2-phenylindole-labeled myoblasts (x4) injected in fibrin glue are found in the infarct wall. (B) Corresponding hematoxylin and eosin stained section (x4). Transplanted myoblasts are surrounded by fibrin glue within the infarct scar. (C) Higher-magnification hematoxylin and eosin section (x10) displaying transplanted myoblasts in fibrin glue. (D) Hematoxylin and eosin stained section (x10) of fibrin glue ex vivo.
