What property of the mammalian embryo permits the production of chimeric mice?

#Unit 5. Developmental Biology
  1. The inner cell mass is highly regulative, so that extra cells derived from the inner cell mass of a different embryo are incorporated without causing defects.
  2. f half of the cells of the inner cell mass are removed and replaced with cells from half of a different embryo's inner cell mass, the embryo will heal and develop normally.
  3. The embryo can develop outside the womb, making surgical manipulations possible
  4. Blastomeres separated at the two-cell stage will regulate and each forms a normal embryo.
