  Catherine Varfaillie of the university of Minnesota was able isolate the potentially ploripotent MPAC from bone marrow populations.  Still there are other powerful stem cells found in BMSC populations, including mesenchymal.  There was a claim of a lübeck stem cell also being ploripotent and formed organoids but that was not peer reviewed, and such claims have disapeared.  Oligofactory cells are believed to be ploripotent, and are located around the nose and brain.  The university of pittsburg also found the amniotic epithelial are also ploripotent which can be obtained from the placenta
