Four embryonic stem (ES) cell lines, designated CE1, CE2, CE3 and CE4, were isolated from C57BL/6J blastocysts. The ratio of normal diploid composition of these cell lines is above 70%. To examine the differentiation...
The aim of the present investigation was to determine if embryonic stem (ES) cells could be isolated from outbred mouse embryos (KM) and if chimeras could be producedly using outbred ES cells. Three ES cell lines,desi...
