The total number of CD8+ve (A, B), CD16+ve (C), and CD8+ve/CD16+ve (D) subpopulations were determined by flow cytometric analysis of PBMNCs harvested from infant macaques one week prior to intracranial MSC administration (−7) and at 14 and 30 days post-transplantation. A) Data were analyzed by comparing all study subjects or only those animals injected with MSCs (w/o shams). B-D) Data were analyzed based on treatment group. Plotted values represent the mean ± SD for each subpopulation. Students T test, *,p<0.05; **,p<0.01; #, p<0.005. LD, low dose; HD, high dose.
