Abstract
Novel cultured inner cell mass (CICM) cells, and cell lines, derived from ungulates, in particular, pigs and cows, and methods for their preparation are provided. The subject CICMs possess similar morphology and express cell markers identically or substantially similarly to ICMs of undifferentiated developing embryos for prolonged culturing periods. Heterologous DNAs may be introduced into the subject CICM cells and cell lines to produce transgenic cells useful for the production of transgenic embryos, fetuses and/or offspring, e.g., by nuclear transfer procedures.
