Short-term rescue by RNA injection of a mitotic arrest mutation that affects the preimplantation mouse embryo.

Abstract

The mutation oligosyndactyly results in syndactyly, abnormal fusion and insertion of certain limb muscles, and diabetes insipidus in heterozygous mice. When homozygous the mutation is lethal; beginning at the blastocyst stage, the homozygous cells arrest in metaphase with intact spindles. The mutant phenotype cannot be corrected by forming aggregation chimeras with wild-type cells, suggesting that the mutation results in a cell autonomous lethal condition. Short-term rescue of the homozygous-induced mitotic arrest can be achieved, however, by cytoplasmic injection of polyadenylated RNA obtained from a rapidly dividing embryo-derived stem cell line.
