Sustained engraftment. Granulocyte and platelet changes in dog E131 conditioned with 200 cGy TBI, given a marrow graft from a DLA-identical littermate on day 0 and postgrafting immunosuppression with mycophenolate mofetil/cyclosporine (MMF/CSP) for no more than 35 days. The bottom panel shows the results of testing for (CA)_n dinucleotide repeats of donor and recipient cells before transplantation (lanes 1 and 2) and recipient cells after marrow transplantation (lanes 3 to 12).
