(57) Researchers then used a karyoplast fusion technique, using an extract from the Sendai virus, (58) which produced reconstructed oocytes which maintained the spindle-chromosomal complexes transferred from the mature oocyte.
To confirm the enucleation of oocyte, the aspirated karyoplast in the pipette was visualized under fluorescent light.
Green fluorescent protein (GFP) gene was used as a foreign gene and a non-transfected somatic cell was utilized as a control karyoplast. Monolayers of porcine cells were established and subsequently transfected with a GFP-expressing gene (pEGFP-N1) using three types of transfection reagents (LipofectAMINE PLUS, FuGENE 6 or ExGen500).
Our earlier studies using asbestos fiber--treated cytoplasts and fusion with non-treated karyoplasts provided circumstantial evidence of the role of mitochondria in fiber genotoxicity (Xu et al.
Budded karyoplasts from multinucleated fibroblast cells contain centrosomes and change their morphology to mi totic cells.
The resulting pronuclei (karyoplasts) in the donor oocytes were microsurgically removed and discarded, and the pronuclei from the patient's oocytes were transferred into the donor's enucleated cells (cytoplasts).
The aspirated karyoplasts were exposed to ultraviolet-light to confirm the presence of nuclei.
