Early mouse preimplantation development is unaffected by microinjection of metallothionein antibodies

Research output: Contribution to journalArticleResearchpeer-review

Abstract

Polyclonal antibodies that cross-react with rodent metallothionein I (MTI) and metallothionein II (MTII) were microinjected in 1-cell and 2-cell mouse embryos, into either the cytoplasm or the nucleus. Regardless of the experimental treatment, mouse embryo development in vitro was not affected and most of the embryos cleaved normally until the morula stage. The results suggest that metallothionein is not essential for normal mouse early preimplantational development, in agreement with recent studies in mice with inactivated MT I and MT II genes. © 1995, Trustees of Princeton University.
