Progression of PCC following cell fusion

Hours after cell fusion	Interphase	PCC ^a
2	100% (16/16)	0%
4	81.2% (13/16)	18.8% (3/16)
6	88.9% (8/9)	11.1% (1/9)

Progression to PCC was evaluated following fibroblast somatic cell fusion in the absence of activation. In total, 41 oocytes collected from four Jills in the absence of hormonal stimulation by mating with vasectomized males were analyzed. The percentage in each category found at the given time points is shown with the fraction of oocytes analyzed in parentheses.

PCC: premature chromosome condensation.

PN: pronuclei.
