Figure 2 Detection of human cells in grafted rat hearts. One month after skeletal myoblast (SM) grafting, immunofluorescence shows that many cells were positively stained for human lamins-A/C (A); some of them expressed (B) neonatal myosin heavy chain (MyHC) (arrows) and (C) adult-fast MyHC. (D) Detection via polymerase chain reaction of human cells in grafted hearts using a human-specific Alu primer.
