inhibits family phosphatases and activates MAPK signaling pathway to maintain pluripotency in porcine induced pluripotent stem cells.

LIN28A, an RNA-binding protein, plays an important role in porcine induced pluripotent stem cells (piPSCs). However, the molecular mechanism underlying the function of in the maintenance of pluripotency in piPSCs remains unclear. Here, we explored the function of in piPSCs based on its overexpression and knockdown.

Characterization of porcine extraembryonic endoderm cells.

Objectives: To date, many efforts have been made to establish porcine embryonic stem (pES) cells without success. Extraembryonic endoderm (XEN) cells can self-renew and differentiate into the visceral endoderm and parietal endoderm. XEN cells are derived from the primitive endoderm of the inner cell mass of blastocysts and may be an intermediate state in cell reprogramming.
