Human placental tissue-

is an excellent source of immature stem cells capable of transformation into almost any tissue in the human body.  The FDA in 2014 approved the placental cells for injection.  There are very few specific studies of this tissue but there have been publications in 2012 showing the cells can differentiate into any organ- that is, they are called pluripotent.  Either fresh or frozen stem cells can be used.  Although the potential is for use is extraordinary, given the unknown risks and nascent state of the science, it would be better to wait a bit before engaging in this therapy.  Painbytes assessment: one thumb down as of 2/15
