Abstract:
Gene-edited mice are the most ideal laboratory animals for studying human gene functions, exploring disease mechanisms, and developing new drugs. Strain resulting from low fertility, aging, illness, etc. can cause irreversible losses to scientific research, so strain rescues of genetically engineering mice require different measures accordingly. Meanwhile, cost control is another key point when a specific technology is applied. First of all, when the only remaining gene-edited mouse in reproductive age suddenly dies, the dead male mouse can be rescued by in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI), while the female mouse can be saved by ovarian transplantation, etc. Secondly, due to aging or diseases, mice can be saved through IVF-embryo transfer (ET) and unilateral epididymal tail assisted reproduction. Thirdly, round sperm injection (ROSI) and ovarian transplantation can be used to save endangered mice before sexual maturity with poor life status. This paper reviews rescue techniques of common endangered mice and their applications, which provides a reference for relevant practitioners to better maintain gene-edited mouse strains.
