Every parent who delivers in an up-market hospital in India today is told by their doctor to go ahead and store their umbilical cord blood stem cells of the baby. They made a lot of promises about how valuable these stem cells are; about how in case the baby has a problem in the future these stem cells can be used to replenish any kind of cell in the body; what makes these stem cells so precious; and why they only have a limited window of opportunity, which is at the time of birth. The marketing spiel is that it's a very cost-effective investment because it could make a world of a difference to their child's health in case she ever develops a medical problem in the future.
