University of Pittsburgh works in conjunction with Planned Parenthood for the continued experimentation on animals with human tissue grafted onto rodents from aborted babies.
They removed human full-thickness fetal skin from the scalp, fat and liver tissue for grafting onto a rodents rib cage on tax payers dime. The reason? To allow Dr. Anthony Fauci human / animal experimentation.
"Human skin tissues were obtained from the scalp and dorsum of donors and were used in developing human skin engraftments with and without hair in the mouse model, respectively. Full-thickness human fetal skin was processed via removal of excess fat tissues attached to the subcutaneous layer of the skin, then engrafted over the rib cage, where the mouse skin was previously excised"
