Research Abstract

The objective of this study was to development of cell therapy using induced pluripotent stem(iPS) cells for dogs with spinal cord injury, and the following results were obtained.(1) We successfully reprogrammed canine embryonic fibroblasts into iPS-like cells using lentiviruses containing 4 transcription factors. Canine iPS-like cell colonies displayed a mouse embryonic stem(ES) cell-like morphology, differentiated to multiple cell types in vitro, and maintained their proliferation and mouse ES-like morphology beyond passage 25.(2) Neurons could be induced from canine iPS-like cells.(3) Bone marrow stromal cell transplantation caused no complications and could have beneficial effects on functional recovery of dogs with spinal cord injury, and further studies are required to apply iPS-like cells for the treatment of these dogs.
