These stem cells may also contain hematopoietic cells which are used to treat hematopoietic and genetic disorders.

However, these stem cells are not that enough in unit cord to treat an adult patient. Placenta is better source to collect stem cells and it carries then ten times more than cord. Some of the blood may return to the neonatal circulation if it the cord is not clamped prematurely. If it is not clamped,

 

a physiological postnatal occlusion can happen with mixing of cold air when internal gelatinous substance swells around cord's veins.

In the United States , the regulatory body for the food and drugs categorized cord blood along with human cells and tissues based products. There are private and public cord blood banks which are working under blood bank regulatory of America . The cord blood can be accredited and have regulations restricted for it. Many other countries also regulate cord blood banks.

Physicians and experts are trying to research to make umbilical cord blood safe enough to be used in more processes for the treatment of other diseases than cancer and genetic disorders.

 

Studies for the treatment of diabetes (type 1) and brain injury through cord blood is in progress. While, researches for the use of cord blood in hearing loss treatment and strokes is already started.

It is also researched that cord blood in some cases, founds to be good for those only from whose cord it has been taken. Like in case of brain injuries, blood cells used for treatment can be rejected by immune system if they do not match but if the cells are of the same person then they will never be rejected. So, this is the reason, researches done by experts are only on those children from which the cord blood is taken.
