Protocol for somatic cell nuclear transfer in the common marmoset.

Area of Science:

• Reproductive Biology
• Developmental Biology
• Primate Research

Background:

• Somatic cell nuclear transfer (SCNT) is crucial for generating genetically identical animals.
• SCNT efficiency in non-human primates, particularly marmosets, is limited by preimplantation embryonic arrest.
• Developing reliable SCNT protocols is essential for advancing primate reproductive technologies.

Purpose of the Study:

• To establish and detail a robust protocol for somatic cell nuclear transfer (SCNT) in the common marmoset.
• To optimize SCNT procedures from oocyte collection to blastocyst development.
• To enhance the efficiency of SCNT in non-human primates.

Main Methods:

• Detailed steps for oocyte collection, in vitro maturation, enucleation, and nuclear transfer using fibroblast or cumulus cells.
• Procedures for oocyte activation and triple epigenetic enhancement.
• Embryo culture techniques up to the blastocyst stage in common marmosets.

Main Results:

• A comprehensive protocol for SCNT in common marmosets is provided.
• The protocol covers all critical stages from oocyte handling to blastocyst development.
• This work facilitates further research and application of SCNT in marmosets.

Conclusions:

• The presented protocol offers a standardized method for SCNT in common marmosets.
• This advancement contributes to improving the efficiency of SCNT in non-human primates.
• The protocol serves as a foundation for future studies in primate reproductive biology and stem cell research.
