Not stem cells
You’re less honest than Joe Biden.
A case in point is the decision by Sanofi Pasteur to no longer use an aborted fetal cell line in producing its polio vaccines, a move recently approved by the FDA.
Sanofi is one of the companies currently developing a COVID-19 vaccine by utilizing “cell lines not connected to unethical procedures and methods.” Inovio Pharmaceuticals and the John Paul II Medical Research Institute are other such companies.
Then what kind of cells were they? Please provide a source.
Stem cell, an undifferentiated cell that can divide to produce some offspring cells that continue as stem cells and some cells that are destined to differentiate (become specialized). Stem cells are an ongoing source of the differentiated cells that make up the tissues and organs of animals and plants.
