Effect of roscovitine pretreatment for increased utilization of small follicle-derived oocytes on developmental competence of somatic cell nuclear transfer embryos in pigs.

The objective of this study was to evaluate the effect of roscovitine pretreatment on the number of matured oocytes per ovary available for somatic cell nuclear transfer (SCNT) and their developmental competence. Irrespective of reproduction status (prepuberty/puberty), the average number of small follicles per ovary (19.3/17.
