I am not the first person who has considered composing poetry to the placenta. One writer begins: “Oh Lady Placenta! What a life you lived in magenta.” Another almost coos to the “constant companion, ...

A calf was born from an embryo lacking cells which form a large part of the placenta, providing new insight into the regenerative capacity of mammalian embryos. Mammalian development starts from a ...

A stem-cell derived human embryo model showing blue cells (embryo), yellow cells (yolk sac) and pink cells (placenta). Scientists have grown an entity that closely resembles an early human embryo, ...

An experimental study from researchers in the Perelman School of Medicine at the University of Pennsylvania links a specific procedure - embryo culture - that is part of the assisted reproduction ...

Researchers have developed a cell culture test to detect substances that are directly or indirectly harmful to embryos. Based on an existing test used for developing new drugs and chemicals, the ...

Understanding the molecular control of placenta formation, the organ which enables fetal growth, is critical in diagnosing and treating related pregnancy complications. A group of scientists at the ...

The effect of genetic changes on the placenta has not been systematically studied to date. Of 103 gene mutations that lead to the death of a developing fetus in mice, 68% caused defects in the ...

Scientists have created a model human embryo with a heartbeat and traces of blood in an advance that offers an extraordinary window into the first weeks of life. The synthetic structure, created from ...

Scientists have created a breakthrough polymer chip designed to mimic a human placenta and embryo to stop the 'unethical and cruel' drug testing on more than two million pregnant mice worldwide each ...
