title: [Green fluorescent protein has no effect on blastocyst development in C57BL/6-Tg(ACTB-EGFP)1Osb/J mice].
abstract: The changes in the state of long-term culture of blastocysts derived from female C57BL/6 mice after crossing with C57BL/6-Tg(ACTB-EGFP)1Osb/J males with a green fluorescent protein transgene EGFP on chromosome 15 were studied. Possible causes of different culture results were analyzed: the preservation of undifferentiated cells as dense clusters in the inner cell mass or their differentiation into extraembryonic endoderm. Comparison of the events going in blastocysts with the -/- or -/EGFP genotypes demonstrated that the GFP presence has no effect on cell processes. This allows us to use embryonic material from this mouse line in experiments that require long-term vital observation of embryonic cells.
