The use of stem cells in injury repair has been extensively investigated. In this study, we examined the therapeutic effects of two transplants (12x106 cells/transplantation) of allogenic adipose-derived stem cells (ASCs) in 11 dogs with chronic spinal cord injury. ASC were cultured in vitro, proliferation and cell viability were evaluated. Cell suspensions were prepared and administered in the intradural space, with a one-week interval between transplants. The animals were submitted to clinical, laboratory, radiographic, tomographic, sensory, motor and cystometric evaluations. Most of the animals were not a breed defined (63.63%), the same proportion for females affected, predominance of vertebral subluxation fracture was observed (81.81%). Before and after the transplants no hematological changes were observed, three animals (27.27%) presented bacterial cystitis, and in relation to motor, cystometry and sensitivity, no improvement was observed; the rates were maintained before and after transplants, predominance of nociceptive absence in most animals (72.73%), and paraplegia and urinary incontinence in the same proportion. In this study it was concluded that the use of ADSCs for the treatment of dogs with chronic spinal cord injury is safe, with a slight improvement in bladder function, but without significantly clinical improvement. |
