AIM To examine the safety and efficacy of mesenchymal stem cell(MSC) therapy for intracerebral haemorrhage with neurological dysfunctions for a year.METHODS MSC were ex vivo expanded from 29 mL(17-42 mL) autologous bone marrow. Patients were randomized to have two intravenous injections of autologous MSC or placebos in four weeks apart. Neurological functions and clinical outcomes were monitored before treatment and at 12~(th), 16~(th), 24~(th), 36~(th) and 60~(th) week upon completion of~(th)e treatment. RESULTS A mean of 4.57 × 10~7(range: 1.43 × 10~7-8.40 × 10~7) MSC per infusion was administered accounting to 8.54 × 10~5(2.65 × 10~5-1.45 × 10~6) per kilogram body weight in two occasions. There was neither adverse event at time of administration nor sign of de novo tumour development among patients after monitoring for a year post MSC therapy. Neuro-restoration and clinical improvement in terms of modified Barthel index, functional independence measure and extended Glasgow Outcome Scale were evident among patients having MSC therapy compared to patients receiving placebos. CONCLUSION Intravenous administration of autologous bone marrowderived MSC is safe and has the potential of improving neurological functions in chronic stroke patients with severe disability.
