Considering you can take stem cells from embryo’s, is there any chance later in scientific development that all

Question: Considering you can take stem cells from embryo's, is there any chance later in scientific development that all embryo's, or babies will have some type of stem cell extracted or stored in case they need it later in life after having an accident or disease? would this acctually stop the body from rejecting it, and is there a chance of the stem cell developing on its own?

  This is a great question charlotteg!
  
  You’ve almost found something which is being done. What is actually being collected is umbilical cord blood, which is blood remaining in the placenta after childbirth. The babies no longer need the placenta and the cord blood contains a lot of stem cells. These stem cells have been used to treat a lot of different blood diseases already, but scientists are also trying to use them to treat Type 1 Diabetes and brain injury. Also, you’re right that a real benefit of these is that they will not be rejected if they are given to the person that they were originally taken from.
  
  But, these are not embryonic stem cells and are slightly more developed and closer to being like blood cells, which is why they have been used to treat blood diseases. When scientists get embryonic stem cells, the embryo they are taken from is thrown away and does not develop into a baby, so there will be no babies that have had embryonic stem cells removed.
  
  Your last question is whether there is a chance of the stem cell developing on its own. I’m not quite sure what you mean, but I’ll try to answer. Stem cells do tend to develop on their own and it takes quite a lot of work in a lab to stop the stem cells from developing and changing. In the case of these cord blood stem cells they would be frozen to make sure they don’t develop or die before they are needed and then they might be made to develop in the lab before transplanting into the patient or they might be injected into the patient and allowed to develop on their own, but this is only if we know they will develop how we want them to develop.
  
  I hope this answers your question!

  Really great question! Just to add to what David says, it is also possible to store stem cells from the umbilical cord, as well as the blood. In fact there is a company which you can pay to store the umbilical cord, the blood and also baby teeth for 25 years. The reason is because the cells from each organ are good for different things, blood is great for making more blood, the cord itself has lots of stem cells which can make other parts of the body, such as bone and cartilage.
