[Effects of several primary factors related to establishment of mouse embryo pluripotent stem cell lines (ES cell line)].
Several primary factors related to establishment of mouse embryo pluripotent stem cell lines (ES cell lines) have been tested comparatively. The results of 825 embryos indicated: (1) Delayed blastocysts were more conducive than normal ones to proliferation of inner cell mass (ICM). (2) Culture medium DMEM with 4 500 mg/l glucose was more advantageous than DMEM with 1000 mg/l glucose to the attachment of explanted blastocysts and to the proliferation of ICM. (3) DMEM without sodium pyruvate was beneficial to appearance of ES cell colonies and to their growth. (4) Feeder layer prepared from the primary culture of mouse embryos had very good effects to the growth and culture of ES cells.
