Japanese researchers from the universities of Waseda, Keio and Kumamoto created artificial blood incapable of causing rejection, Daily Daily Yomiuri. New blood, in contrast to the donor blood, does not have a group, Rhesus factor and can not tolerate viral infections.
The main function of blood is the delivery of oxygen to all organs and tissues. In natural conditions and in previously created blood substitutes, this role is performed by hemoglobin. Japanese instead of hemoglobin used a modified protein albumin.
In order to force albumin to transfer oxygen, scientists attached to it an iron-containing hemoglobin fragment - heme. This protein was called gemalbumin.
Gemalbumin is much less than red blood cells or hemoglobin. Therefore, artificial blood can deliver oxygen, even in clogged blood vessels. For example, with a heart attack or stroke.
There are already technologies for mass production of such blood. If necessary, the drug can be stored for a long time. Use of artificial blood in medical practice will become possible after the completion of all tests. Scientists believe that this will happen in two years.
