Joy Kong argues that stem cells from umbilical cord and placenta beat adult sources like bone marrow and fat. They have longer telomeres, secrete more growth factors, and can differentiate into more cell types. Cord cells are younger and more metabolically active.
Doctors are thinking that all different sources of stem cells, they think they're all equal or have similar efficacy. So whether or not you're getting cells from the umbilical cord or from a person's own bone marrow or fat, that they are very similar. But indeed they are not. Because studies from all around the world have shown that cells from the earlier sources, the placenta, the umbilical cord, actually have higher potency. They secrete more growth factors, they have longer te, they have more vibrant mitochondria, they're more metabolically active, they have more potential to differentiate into different tissue and cell types, and they are also safer.
