Abstract

Embryonic diapause in mammals describes a transient reduction of proliferation and developmental progression occurring at the blastocyst stage. It was first described in the European roe deer (Capreolus capreolus) in the 19th century, and later found to occur in at least over 130 mammalian species across several taxa. Diapause is often displayed as an interruption, a halt, or an arrest of embryonic development. In this review, we explore reduced, but not stopped pace of growth, proliferation and developmental progression during embryonic diapause and revisit early embryonic proliferation and continued slow development as peculiar phenomenon in the roe deer.

Keywords: Blastocyst; Development; Embryo; Pre-implantation; Uterus.
