So, Haeckel proposed, by examining the development of an embryo you could read its entire evolutionary history in the transition from one stage to another. In fact, this isn't strictly true ...

The fact that many human embryos die at an early stage of development (pre-implantation) provides no evidence whatsoever for the proposition that they are not embryonic human beings — no more ...

"We want to know how cells organize themselves into an embryo-like model ... complete representation of what's going on in early stages of development, and can capture the background," Lodewijik ...

In the mouse developing embryo, she previously demonstrated a bias at the two-cell stage: one cell contributed more to fetal tissue and the other to the placenta. 4 “We know so little about the very ...

While some animals like mammals have a limited ability to regenerate lost tissues, planarians can be cut roughly in half and ...

They show that rather than exclusively providing energy to the cell, glycolysis is able to control, at different stages of early embryonic development, cell fate decisions and the end-state appearance ...
