Limit on Lab-grown Human Embryos Dropped by Stem Cell Body


Limit on Lab-Grown Human Embryos Dropped by Stem Cell Body
The International Society for Stem Cell Research relaxed the famous 14-day rule on culturing human embryos in its latest research guidelines

The international body representing stem-cell scientists has torn up a decades-old limit on the length of time that scientists should grow human embryos in the lab, giving more leeway to researchers who are studying human development and disease.
Previously, the International Society for Stem Cell Research (ISSCR) recommended that scientists culture human embryos for no more than two weeks after fertilization. But on 26 May, the society said it was relaxing this famous limit, known as the ‘14-day rule’. Rather than replace or extend the limit, the ISSCR now suggests that studies proposing to grow human embryos beyond the two-week mark be considered on a case-by-case basis, and be subjected to several phases of review to determine at what point the exp ....

First human-monkey embryo sparks ethical debate

IWK Bureau
A joint team of US and Chinese scientists have, in breakthrough research, grown human cells in monkey embryos in a laboratory for up to 20 days. The development, which has sparked ethical debates, has implications for developing new models of human biology and disease.
Interspecies chimeras in mammals have been made since the 1970s, when they were generated in rodents and used to study early developmental processes.
In the current study, detailed in the journal Cell, six days after the monkey embryos had been created, each one was injected with 25 human cells. The cells were from an induced pluripotent cell line known as extended pluripotent stem cells, which have the potential to contribute to both embryonic and extra-embryonic tissues. ....
