AI Technical Summary

Problems solved by technology

Egg cells tend to have low tolerance to damage during mechanical enucleation, affecting enucleation efficiency
The disadvantage of this method is that the mechanical damage to the cells is relatively large, the equipment requirements are high, the operator is highly skilled and time-consuming

Abstract

The invention discloses a method for removing the nucleus of an oocyte through chemical induction. The in-vitro oocyte is induced and treated by decarboxylated colchicine and cycloheximide, and in thefirst division later period of the oocyte after a certain period of time, chromosomes cannot be separated and discharged along with a polar body. The method for removing the nucleus of the oocyte through chemical induction is easy and convenient to operate, a large number of nucleus-free oocytes can be obtained, the nucleus removing efficiency is high, and the method is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of cell biology, in particular to a method for chemically inducing the removal of egg cell nuclei. Background technique [0002] Since the beginning of the 21st century, great achievements have been made in the application of life sciences, especially animal cloning technology to genetic breeding, and have made great contributions to human agriculture and life and health. Somatic cell nuclear transfer cloning technology has successively cloned pigs, cattle, sheep, mice and other animals in mammals. It provides a new research method for life science, human medicine and many other fields. The technology of somatic cell nuclear transfer involves several key technologies, among which the removal of oocyte nuclear material is one of the key technologies. [0003] The number of removed oocyte nuclei is an important factor related to the construction of reconstructed embryos. In the current situation of low nucle...
