These cells are called “pluripotent” (L. “many” + “powers”) because one of these undifferentiated cells can become any of a variety of different blood cells. These include the various white blood cells that protect against bodily infection, platelets that help the blood to clot, and the red blood cells that carry oxygen throughout the body.

Veritas? Harvard's Stem Cell Initiative

Last night I read a press release announcing Harvard University's launch of a privately funded program that will create cloned embryos for the purpose of embryonic stem cell research. I wondered how the institution would handle the ethical controversy surrounding the procedure so I read an article in the Harvard Gazette.[1] Doing so left me thinking how ironic it is that the school's seal bears the Latin word for "truth."
