The U.S. Food and Drug Administration signed a new contract on July 25 to acquire “fresh” human fetal tissue to transplant into “humanized mice” so that these mice will have a functioning “human immune system,” according to information published by the FDA and the General Services Administration.

“The objective is to acquire Tissue for Humanized Mice,” said a June 13 FDA “presolicitation notice” for the contract.

The contractor, the notice said, would “provide the human fetal tissue needed to continue the ongoing research being led by FDA.

“Fresh human tissues are required,” said the notice, “for implantation into severely immune-compromised mice to create chimeric animals that have a human immune system.”
