Phenotype of splenocytes from CTLA4Ig-treated or control rats.

Splenocytes were harvested on day 10 after transplantation from CTLA4Ig-treated or control LEW.1A rats that received LEW.1W heart transplants. Cells were double labeled with MAbs recognizing the indicated antigens. Numbers within each window represent the percentage of positive cells. Results are representative of 3 independent experiments with a total of 4 animals in each group.
