WHEN STEM CELLS AND THEIR AMAZING PROPERTIES FIRST MADE THE NEWS, MUCH OF THE FOCUS WAS ON A SPECIFIC TYPE CALLED “EMBRYONIC” STEM CELLS. MANY PEOPLE HAVE RAISED ETHICAL CONCERNS ABOUT EMBRYONIC STEM CELLS, PRIMARILY BECAUSE THEY ARE HARVESTED FROM DESTROYED HUMAN EMBRYOS LEFT OVER FROM IN-VITRO FERTILIZATION.
EMBRYONIC STEM CELLS
REQUIRE DESTRUCTION OF HUMAN EMBRYOS
COME FROM ANOTHER PERSON AND MAY BE REJECTED BY THE PATIENT’S BODY
MAY CAUSE TUMORS AT THE POINT OF INJECTION
ADULT STEM CELLS
DO NOT HARM THE DONOR
COME FROM THE PATIENT’S OWN BODY AND WILL NOT BE REJECTED
HAVE SHOWN NO RISK FOR TUMOR FORMATION, SUPPORTED BY A STUDY OF NEARLY 2,000 PATIENTS WITH AN AVERAGE FOLLOW-UP OF MORE THAN 12 YEARS
