Co-infusion of autologous adipose tissue derived neuronal differentiated mesenchymal stem cells and bone marrow derived hematopoietic stem cells, a viable therapy for post-traumatic brachial plexus injury: a case report.

Stem cell therapy is emerging as a viable approach in regenerative medicine. A 31-year-old male with brachial plexus injury had complete sensory-motor loss since 16 years with right pseudo-meningocele at C5-D1 levels and extra-spinal extension up to C7-D1, with avulsion on magnetic resonance imaging and irreversible damage. We generated adipose tissue derived neuronal differentiated mesenchymal stem cells (N-AD-MSC) and bone marrow derived hematopoietic stem cells (HSC-BM). Neuronal stem cells expressed β-3 tubulin and glial fibrillary acid protein which was confirmed on immunofluorescence. On day 14, 2.8 ml stem cell inoculum was infused under local anesthesia in right brachial plexus sheath by brachial block technique under ultrasonography guidance with a 1.5-inch-long 23 gauge needle. Nucleated cell count was 2 × 10 4 /μl, CD34+ was 0.06%, and CD45-/90+ and CD45-/73+ were 41.63% and 20.36%, respectively. No untoward effects were noted. He has sustained recovery with re-innervation over a follow-up of 4 years documented on electromyography-nerve conduction velocity study.
