ARTICLE HIGHLIGHTS
Research background
Induced pluripotent stem cells (iPSCs) derived from large animal models can greatly contribute to translational medicine and also to animal production, although robust and safe protocols are still uncommon. Cellular reprogramming of urine derived cells presents great advantages for iPSCs use in regenerative medicine due to the easy collection, injury and stress free, and is herein described for the first time in large animals.
Research motivation
The porcine iPSCs generation is promising for both translational medicine and animal production; and iPSCs derived from a noninvasive cell source would greatly contribute to its large-scale use, especially for in vivo autologous purposes using large animal models.
Research objectives
Isolate cells from porcine urine and generate iPSCs through their transduction with Yamanaka’s human or murine factors.
Research methods
We isolated urine-derived cells (UDCs), which were reprogrammed in vitro into pluripotent cells. The porcine induced pluripotent cells generated were investigated regarding morphology, markers and endogenous transcripts related to the pluripotency.
Research results
From the porcine urine samples we isolated the UDCs, and colonies were formed when murine factors were used in the reprogramming. Endogenous pluripotent markers were detected in all three isolated lineages, in different time points during in vitro culture, and were able to differentiate into embryoid bodies (EBs) with mesoderm and ectoderm transcripts.
Research conclusions
In an unprecedented way, UDCs were isolated from noninvasive collection and reprogrammed into a pluripotent state using murine factors, the cells formed colonies presenting the expected characteristics, such as colonies with limited borders, transcripts and markers related to the pluripotency, and ability to differentiate into EBs.
Research perspectives
As we reported here, iPSCs can be derived from an easy collection and noninvasive source in the porcine model, and with our methodology represents a novel tool for iPSCs production in large animals and biomedical models of regenerative or translational medicine.
