Several animals can pause pregnancy, a strategy called embryonic diapause. This adaptation allows embryos to remain dormant until conditions improve for survival. Kangaroos and bears are among the ...

In order for vertebrate embryos to develop their body axes, they require what is known as an embryonic signaling center. This group of cells provides the instructions that determine where up and down, ...

Researchers reveal that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of infertility and early human development. CRCHUM researcher Sophie ...

A new model for embryo research Unlike other common laboratory animals, such as mice, guinea pigs have a preimplantation development that is more comparable to that of humans in terms of timing and ...

In vitro embryo production (IVEP) in sheep and goats encompasses a sequence of biotechnological steps: recovery of oocytes, maturation of oocytes under controlled conditions, fertilisation with ...

In vitro embryo production (IVEP) in cattle encompasses a suite of technologies designed to recover oocytes from donor animals, mature and fertilise them under controlled laboratory conditions, and ...

The first few days of a human embryo’s development, known as pre-implantation, are important. It’s when the first cells are formed, and these decide if the embryo can survive, how it will implant in ...
