Furthering The Study Of Human Embryos

A group of scientists recently have managed to grow some cells which are the closest model we currently have to an embryo. A lot can come from studying these new models because they are very close to that of a human embryo and they are able to be studied as they grow whereas a real human embryo would have to be inserted into the uterus at a much earlier stage then what these cells appear to be. These human embryo models are grown from stem cells, but with all the excitement that has come from this discovery many are also nervous with the fact that scientist might soon now be able to grow a human in a lab. This new human embryo model is raising questions as to whether models can be grown after the normal 14 day of normal human development after fertilization.
