The current practice of freezing embryos—used to assist reproduction in humans or animals or to conserve endangered species—routinely causes ice to form within the cells, ripping through cell ...
Studying the early development of human embryos is challenging due to ethical constraints and technical difficulties. Therefore, animal models are often used to understand the biological processes ...
Scientists at Colossal Biosciences say they have successfully hatched healthy chicks using a fully artificial egg system.
Embryo development in livestock underpins global food security and genetic improvement programmes. From the first mitotic divisions in the zygote to the formation of the blastocyst, the timing, ...
Hair, nails, and horns, all made up of keratin, are some of the hardest and most resilient structures in animals. Inside zebrafish cells, keratin plays a distinct role, giving them the strength they ...
At least 8% of the human genome is genetic material from viruses. It was considered ‘junk DNA’ until recently, but its role in human development is now known to be essential Researchers at the Spanish ...
NAIROBI, Kenya (AP) — A rhinoceros was impregnated through embryo transfer in the first successful use of a method that conservationists said might later make it possible to save the nearly extinct ...
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 ...
CRCHUM researcher Sophie Petropoulos and her team reveal for the first time that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of ...
