Factors influencing chromosome condensation and development of cloned rat embryos.


Factors influencing premature chromosome condensation (PCC) in transferred rat nuclei have been examined. Chromosome condensation of rat cumulus cell nuclei did not occur when the cell nuclei were injected into enucleated rat oocytes. By contrast, chromosome condensation did occur after transfer to enucleated mouse oocytes or intact rat oocytes. In the… (More)
