We investigated intra-arterially administered autologous bone marrow mononuclear cells (MNCs) in rats with acute ischemic stroke. Long Evans rats (2 to 3 months or 12 months old) underwent tandem reversible common carotid artery (CCA)/middle cerebral artery (MCA) occlusion (CCAo/MCAo) for 3 h and then 24 h later underwent tibial bone marrow harvest. Ten million or 4 million cells were re-injected by an intra-carotid infusion. Control animals underwent marrow needle insertion and then saline injection into the carotid artery. Animals were assessed on a battery of neurological tests. MNCs in the ischemic brain were tracked using Q-dot nanocrystal labeling. Infarct volume and cytokines in the ischemia-affected brain were analyzed. Cell-treated animals in the younger and older groups showed improvement from 7 to 30 days after stroke compared with vehicle-treated animals. MNCs significantly reduced infarct volume compared with saline. There was a significant reduction in tumor necrosis factor-α, interleukin-1α (IL-1α), IL-β, IL-6, and a significant increase in IL-10 in injured brains harvested from the cell-treated groups compared with saline controls. Labeled MNCs were found in the peri-infarcted area at 1 h and exponentially decreased over the ensuing week after injection. Autologous bone marrow MNCs can be safely harvested from rodents after stroke, migrate to the peri-infarct area, enhance recovery, and modulate the post-ischemic inflammatory response.

In response to acute ischemic stroke, large numbers of bone marrow stem cells mobilize spontaneously in peripheral blood that home onto the site of ischemia activating the penumbra. But with chronicity, the numbers of mobilized cells decrease, reducing the degree and rate of recovery. Cellular therapy has been explored as a new avenue to restore the repair process in the chronic stage. A 67-year-old Indian male with a chronic right middle cerebral artery ischemic stroke had residual left hemiparesis despite standard management. Recovery was slow and partial resulting in dependence to carry out activities of daily living. Our aim was to enhance the speed of recovery process by providing an increased number of stem cells to the site of injury. We administered autologous bone marrow mononuclear cells intrathecally alongwith rehabilitation and regular follow up. The striking fact was that the hand functions, which are the most challenging deficits, showed significant recovery. Functional Independence Measure scores and quality of life improved. This could be attributed to the neural tissue restoration. We hypothesize that cell therapy may be safe, novel and appealing treatment for chronic ischemic stroke. Further controlled trials are indicated to advance the concept of Neurorestoration.

Background: Bone marrow mononuclear cells (MNCs) are under investigation as an autologous cell-based therapy for acute ischemic stroke. Both intravenous (IV) and intra-arterial (IA) delivery of MNCs have been brought forward to clinical trials. However, the optimal route of administration for these cells is still unknown and debated. In the present study, we performed a direct comparison of IV vs IA administration of MNCs in a rodent stroke model. Methods: Long Evans adult male rats were subjected to middle cerebral artery occlusion (MCAo) for 90 minutes. At 24 hrs after stroke, animals were randomly assigned to either receive saline IV (N=5) or autologous bone marrow derived MNCs 30 million cells/kg via IV (N= 9) injection or an IA (N=8) administration of autologous MNCs 30 million cells/kg. IA infusion was performed over 5 minutes with an infusion pump. Contralateral forepaw use was evaluated by an investigator blinded to treatment groups up to 28 days after stroke. Stroke lesion volume was also measured at 28 days after stroke. Serum cytokines were analyzed from 4 to 28 days after stroke. Results: MNCs improved functional recovery and reduced lesion size compared with saline treatment at 28 days after stroke ( Fig A & Fig B, p<0.05). However, there was no significant difference between IV and IA MNC treated groups in either histological or functional outcomes. Serum levels of IL-10 were elevated in animals that received either IV or IA MNCs from 4 to 28 days after stroke, compared with saline controls (Fig C, p<0.05). In addition, serum levels of TNF-α were significantly reduced (Fig D, p<0.05) in both IV and IA MNC treated groups compared to saline controls. We did not observe differences in cytokine levels between IA and IV MNC treated groups for IL-10 and TNF-α. Furthermore, only intravenously administered MNCs led to a significant reduction in serum IL-1β levels, at 4 days after stroke, compared to saline treated controls (p<0.05). Conclusion: This is the first study to directly compare delivery routes of bone marrow derived MNCs in a rodent stroke model and assess long term outcomes. MNCs improved neurological recovery and reduced infarction sizes after stroke but we found no differences in outcome based on route of administration. We also found no evidence that either delivery route is superior in modulating the systemic inflammatory response after stroke. These findings have direct clinical implications for the design of clinical trials testing MNCs in patients with ischemic stroke.
