Scientists say they have taken a big step in the production of red blood cells in the quantity that will be used to help patients.
Red cells are maintained in the laboratory, but the problem is the required level.
One group of scientists at the University of Bristol with blood and transplant department limetengeza techniques to produce a large amount of blood.
The blood of the lab will be priced higher compared to normal blood.
For it will be used among people who have blood type.
The old system involving use kinachotengeza stem cell red blood cells in the body and kuzibembeleza generate such cells in the laboratory.
However, each cell becomes easily exhausted and unable to produce more than 50,000 red cells.
Iliotengezwa contact with the group of scientists of Bristol aims to keep early stem cells when they are in abundance.
Doctor Jay Frayne one of the researchers of the group said: We have shown our ability to produce red blood cells that can be used in hospitals.
