MLC data is presented as count per minute (CPM) of E934 (A) or E932 (B), which is the reactivity against autologous (auto), DLA-haploidentical (haplo) or unrelated donor cells (URD) at different time points of transplantation. Chimerism plots represent donor chimerism in E934 (A) and E932 (B) at different time points post-transplantation. Bars below the chimerism plots represent duration and dose of immunosuppression which consisted of cyclosporine (CSP, 30mg/kg/day from day -1 to +100) and mycophenolate mofetil (MMF, 20 mg/kg/day from day 0 to +40 and 10mg/kg/day from day+41 to +100). Abbreviations: ConA, concanavalin-A; DM5+, donor chimerism in canine myeloid cells marker positive cells; MNC, mononuclear cells; TCR, donor chimerism in αβ-T-cell receptor positive cells.
