Abstract

Experiments were conducted to determine the effects of feeder layers composed of different cell types on the efficiency of isolation and the behavior of porcine embryo-derived cell lines. Inner cell masses (ICM) isolated from 7- to 8-d-old embryos were plated on feeder layers composed of Buffalo rat liver cells (BRL), a continuous cell line of murine embryonic fibroblasts (STO), STO combined with BRL at a 9:1 and 1:1 ratio, STO with BRL-conditioned medium (STO + CM), porcine embryonic fibroblasts (PEF), PEF combined with BRL at a 9:1 and 1:1 ratio, porcine uterine epithelial cells (PUE), murine embryonic fibroblasts (MEF), or an epithelial-like porcine embryo-derived cell line (PH3A). It was found that embryo-derived cell lines could be isolated only from the STO and the STO with BRL-conditioned medium treatments. The isolated cell lines were of epithelial-like and embryonic stem cell-like (ES-like) morphology. The feeders tested had an effect on the behavior of plated ICM. Some feeders, represented by PUE, BRL, STO:BRL (1:1), PEF:BRL (1:1), and PH3A, did not promote attachment of the ICM to the feeder layer; others, represented by STO and MEF, allowed attachment, differentiation and proliferation. On PEF feeders the ICM spread onto the feeder layer after attachment without apparent signs of proliferation or differentiation. None of the feeders tested increased the efficiency of isolation or the growth characteristics of embryo-derived (both ES-like and epithelial-like) cell lines over that of STO feeders.
