A
Abstract:
To provide a method for improving the rate of developing mammalian fertilized ovum, to be utilized in the fields including medicine, veterinary medicine and livestock industry.
This method comprises adding a vascular endothelial growth factor at a specified concentration (preferably 1-10 ng/mL) to a medium for developing mammalian fertilized ova and conducting a coculture with cumulus cells as the supporting cells. By this method, the normal rate of developing the fertilized ova can be raised and the number of transplantable embryos can be increased as a result of the coculture with the supporting cells and owing to the vascular endothelial growth factor acting effectively on the medium for developing the fertilized ova.
