AB Background and Purpose. BM-MNCtransplantation improves recovery in experimentalmodels of ischemic stroke. Clinical trials are ongoing to test efficacy in stroke patients. However, whether cell dose is related to outcomes is not known. Methods. We performed a pooling data analysis of two pilot clinical trials with autologous BM-MNCs transplantation in ischemic stroke patients. Cell dose and route were analyzed to evaluate their relation to good outcome (m-Rankin scale [mRS] score 0-2) at 6 months. Results. Twenty-two patients were included. A median of 153 x 10(6) (+/- 121 x 10(6)) BM-MNCs was injected. Intra-arterial route was used in 77.3% of cases. A higher number of cells injected were associated with better outcomes at 180 days (390 x 10(6) [320-422] BM-MNCs injected in those patients with mRS of 0-2 at 6 months versus 130 x 10(6) [89-210] in those patients with mRS 3-6, p = 0.015). In the intraarterially treated patients, a strong correlation between dose of cells and disability was found (r = -0.63, p = 0.006). A cut point of 310 x 10(6) injected cells predicted good outcome with 80% sensitivity and 88.2% specificity. Conclusions. Similar to preclinical studies, a higher dose of autologous BM-MNC was related to better outcome in stroke patients, especially when more than 310 x 10(6) cells are injected. Further interventional studies are warranted to confirm these data.
