Guidance that prevents scientists from growing and studying human embryos in a dish beyond 14 days is to be “relaxed” under landmark changes unveiled by an international consortium of experts. The International Society for Stem Cell Research (ISSCR), which oversees and shapes the universally followed guidance, has not gone as far as to lift the limit but says it would be open to reviewing and scrutinising proposed research that seeks to examine.
LONDON (AP) New guidelines released Wednesday remove a decades-old barrier to stem cell research, recommending that researchers be allowed to grow human embryos longer under limited conditions.
For decades, scientists have been prohibited from keeping human embryos alive in their labs for more than 14 days. The prohibition was aimed at avoiding a
