WebTwo methods are used to extract ES cells: the inner cell mass, which consists of the cells that will form the embryo, must be removed to extract the ES cells. Removing this mass often results in the death of this part of the embryo, but it is vital for stem cell research. To obtain a high yield of quality ES cells, embryos must be genetically identical. WebEmbryonic stem cells (ESCs) are found in the inner cell mass of the human blastocyst, an early stage of the developing embryo lasting from the 4th to 7th day after fertilization. In normal embryonic development, they disappear after the 7th day, and begin to form the three embryonic tissue layers. ESCs extracted from the inner cell mass during the blastocyst …

WebThe hollow blastocyst—which is where embryonic stem cells come from—contains a cluster of 20-30 cells called the inner cell mass.
