FIG. 1.

Schematic representation of the experimental design. Recipient animals ubiquitously expressed green fluorescent protein (GFP) and were deficient for the expression of CD26. Donor amniotic epithelial cells (AECs) were isolated from CD26-expressing rats that did not express GFP. In the presence of fusion events, fused cells would share genetic information and coexpress GFP and CD26, whereas in the absence of cell fusion, clusters of donor-derived cells would only express CD26.
