A pig embryo with a heart containing human cells has reportedly survived for 21 days. This research achievement significantly advances the potential for developing ‘transplantable hearts’ for human ...

Scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic disorders and in understanding why ...

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

Chinese researchers are preparing the details for the publication of another scientific milestone, the creation of a chimera with a human heart and a kidney developed from human stem cells in pig ...

Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...

Scientists have created the miracle of life — no male or female necessary. Using only a mixture of stem cells, University of Cambridge researchers were able to generate a live, “synthetic” mouse ...

BOSTON -- A research company reported Sunday it had cloned the first human embryo, a development it said was aimed at producing genetically matched replacement cells for patients with a wide range of ...
