Induced Pluripotent Stem-Like Cells Derived from Ban, a Vietnamese Native Pig Breed

Induced pluripotent stem cells (iPSc) is a promising technology for applying in bio-medicine and biodiversity conservation. In the present study, we isolate and culture fibroblasts from Ban – a Vietnamese native pig breed and transfer episomal plasmid containing genes Oct3/4, Sox2, Klf4, l-Myc, LIN28 and EBNA1 in order to reprogram cells. We isolated, cultured and cryopreserved successfully 9 primary fibroblast lines from Ban (culture percentage is 90.0%). Plasmids was successfully transferred into Ban fibroblasts with high efficiency. Changes in morphology of fibroblasts into pluripotent stem-like cells showed that they had been reprogrammed under the effect of transferred genes. The pluripotency signal was further proved by in vitro differentiation by formation of embryoid body in all 3 transfected cell lines. The results showed that pluripotent stem-like cells has successfully derived in Ban pigs. Keywords— Ban pig, fibroblast, gene transfer, iPS-like cells.
