Embryoid bodyEmbryoid bodies (EBs) are three-dimensional aggregates of pluripotent stem cells. EBs are differentiation of human embryonic stem cells into embryoid bodies comprising the three embryonic germ layers. The pluripotent cell types that comprise embryoid bodies include embryonic stem cells (ESCs) derived from the blastocyst stage of embryos from mouse (mESC), primate, and human (hESC) sources. Additionally, EBs can be formed from embryonic stem cells derived through alternative techniques, including somatic cell nuclear transfer or the reprogramming of somatic cells to yield induced pluripotent stem cells (iPS).
