Popis: Autophagy is an essential cellular degradation pathway in the mammalian preimplantation embryo. In this review, the process of autophagy is outlined and its function pertaining to preimplantation embryos is discussed. The current methods of measuring autophagy in preimplantation embryos are also summarized, with highlights of advances and challenges that one may encounter when examining preimplantation embryo autophagy. This article identifies the techniques, assays, and available models that are viable but infrequently used in the context of examining autophagy in preimplantation embryos. We aim to bring attention to alternative assays that could contribute to future analysis of autophagic pathways in preimplantation embryos.
