Embryonic stem cells can indeed be harvested from human embryos that are produced during in vitro fertilization (option A is true). In terms of pluripotent animal stem cells, the only known ones are derived from embryos (option B is also true). Additionally, the manner in which embryonic stem cells differentiate can be channeled by appropriate signals (option C is true). Therefore, options A and C are correct, making option E the best choice.
