Abstract

The invention discloses a method for treating a cattle somatic cell cloning embryo. Specifically, the method comprises the following steps: 1) injecting a to-be-transplanted cattle somatic cell into a de-nucleated oocyte and electrically fusing, selecting successfully fused cattle somatic cell cloning embryos after electrically fusing for 1 h and then performing activation treatment; and 2) after performing activation treatment on the cattle somatic cell cloning embryos, transferring into a G1.3 culture solution and culturing. The invention also relates to a culture solution used in the activation process of the cattle somatic cell cloning embryo and the culture solution used in an in vitro culture process of the cattle somatic cell cloning embryo. The method disclosed by the invention shows excellent technical effects as described in the description of the invention.

Description

technical field [0001] The invention belongs to the technical field of animal somatic cell cloning, and relates to a method for processing bovine somatic cell cloned embryos, in particular to a method for processing bovine somatic cell cloned embryos constructed based on somatic cell nuclear transfer. The method for processing bovine somatic cell cloned embryos of the present invention can overcome one or more defects in the prior art and present the advantages of one or more aspects of the present invention. Background technique [0002] Somatic cell cloning is a technology with great research and commercial value, which can be applied to therapeutic cloning, disease models, human organ transplantation, animal transgenic research, protection of endangered animal breeds, expansion of excellent livestock breeds, etc. But so far the efficiency of somatic cell cloning is still not high, which significantly restricts the wide application of this technology. [0003] At present,...
