Hematopoietic recovery following infusion of ZFN mRNA-electroporated HSPCs. At the indicated time points post-transplant, peripheral blood was drawn from animal IDs A11217 (red), A11210 (blue), Z12161 (orange), and Z12220 (green). Automated differential counts were used to quantify (A) WBCs, (B) platelets, (C) neutrophils, and (D) lymphocytes. Dashed lines represent normal values for each count.
