Axonal regeneration of peripheral nerves with bone marrow mesenchymal cells. Study in sheep animal model
Objectives
Study in sheep models promoted by ITRT and EGARSAT to evaluate the regenerative potential of adult stem cells when applied to peripheral nerve lesions.
Methodology
1 cm defects were created in the radial and tibial nerves of the sheep. Bone marrow was also obtained from the animals and expanded mesenchymal stem cells were selected and cultured.
At 3 weeks a new surgery was performed that consisted of encompassing the defect in a tube of resorbable material (biochamber) in which the cells were infused.
The study was carried out in the experimental operating room of the Hospital Clínico Veterinario of the Universitat Autònoma de Barcelona with prior approval under the control of the Ethics Committee in Animal and Human Research. Cells were selected and expanded in the LAGENBIO lab at the Faculty of Veterinary Medicine of Universidad de Zaragoza.
Results
The results obtained in the pathological study performed 6 months after treatment were satisfactory, demonstrating the viability and efficacy of expanded mesenchymal stem cells applied to peripheral nerve lesions.
