On June 23rd a Chinese team presented the most complete attempt yet. In a paper published in PNAS, a journal, they report ...

Sea anemones may hold the key to the ancient origins of body symmetry. A study from the University of Vienna shows they use a ...

A hybrid embryo is a mixture of both human and animal tissue. There are several types of hybrid embryo (listed below), but recent controversy has focused on cytoplasmic embryos.

Scientists hope the embryo models, grown without eggs or sperm, could also one day reduce the use of animals in research or supplement transplants. Synthetic Mice Embryos Grow Brains and Hearts ...

Another would see whether similar animal embryo models could develop into live animals when implanted into hosts. These tests would, of course, be ethically regulated by authorities, the authors said.

They include creating embryo models of large animals like pigs and monkeys and implanting them into those species to see if they can develop normally and go on to produce fertile offspring of ...

The stem cell-based embryo model (SCBEM) takes advantage of the flexibility of pluripotent stem cells (non-reproductive cells ...

A study from the University of Vienna reveals that sea anemones use a molecular mechanism known from bilaterian animals to form their back-to-belly body axis. This mechanism ("BMP shuttling") enables ...

NAIROBI, Kenya (AP) — Researchers say a rhinoceros was impregnated through embryo transfer in the first successful use of a method that they say might later make it possible to save the nearly ...

In a remarkable—if likely controversial—feat, scientists announced today that they have created the first successful human-animal hybrids. The project proves that human cells can be introduced ...
