Germ line specific expression of a vasa homologue gene in turbot (Scophthalmus maximus): evidence for vasa localization at cleavage furrows in euteleostei.

abstract：:Hoechst 33342 (H342), in combination with ultraviolet (UV) irradiation, is frequently used to aid or confirm the enucleation of porcine oocytes in somatic cell nuclear transfer programs. The exposure of oocytes to H342 and UV irradiation has a deleterious effect on the development of in vitro-fertilized porcine oocyte...
