✦ Synopsis
Abstract
Interspecific hybrid cells were produced using Sendai‐virus‐mediated fusion of interphase blastomeres from 2‐cell embryos with ovulated oocytes of the mouse and bank vole. Under the influence of the cytoplasm of' oocytes (arrested in metaphase II) premature chromosome condensation occurs in the nuclei of blastomeres, thus implying that the cytoplasmic factor which induces chromosome condensation is not species specific, at least not between these two species.

## Abstract Based on the criteria of relative size and cell surface polarization, subpopulations of outer (larger, polar) and inner (smaller, apolar) blastomeres have been isolated from mouse 16‐cell morulae and reaggregated in groups of 16 cells, and the developmental potential of the aggregates h
An improved method for isolating mouse blastomeres by electrically destroying the other blastomeres inside the zona pellucida is described. Instruments required are two micromanipulators connected to a n inverted microscope and an electronic stimulator equipped with an isolator. The target blastomer
In animal oocytes, the centrosome exists as an acentriolar aggregate of centrosomal material that is regulated in a dynamic manner throughout the process of meiotic maturation. Recently, it has been demonstrated that in female meiotic systems spindle assembly is likely regulated by chromosomal and m
