On May 16, 2021, the International Society for Stem Cell Research called for consideration of research on human embryos beyond 14 days of gestation. Current policy is to destroy such embryos before that date when the nervous system begins to develop.  Stem cell research on human embryos is legal in the US, but there are restrictions on government funding and their use.  (See the tab on this page)

Science has irrefutably concluded that human embryos are people in the earliest stages of development.  Two US Congressmen have stated that the ISSCR has shown an utter disregard for the value and dignity of human life. 

The Society also recommended lifting restrictions on creating “chimera” embryos that contain both human and animal cells. The same two Congressmen have also introduced the “Human-Animal Chimera Prohibition Act.”  Pro-life supporters find the concept of destroying a human life and creating a life form consisting of a mixture of human and animal cells a horrifying idea.
