The dorsoventral polarity of Drosophila egg is established by means of signaling between the germ line-derived oocyte and the surrounding somatic follicle cells.
Conclusion The electrofusion efficiency may he improved by inserting more somatic cells into PVS when the somatic cells have a low electrofusion efficiency with oocytes.
The process of somatic cell nuclear transfer involves removing genetic material from the nucleus of a host egg cell and replacing it with the nucleus from adult cells.
