Researchers at Weill Cornell Medicine have developed an innovative method for obtaining blood cells (adult cells) from the endothelial cells of blood vessels (see HERE) to imporove blood diseases treatment. A peculiar characteristic of this technique is that abundant blood cells can be generated to be transplanted in a sufficient amount in patients with blood diseases. For now, however, the research team has been unable to demonstrate that these graft cells in hematology patients generate functioning human cells with sufficient regenerative potential. Nevertheless, this is a first major step for treating blood diseases that currently require repeated transfusions.
From an ethical point of view, the fact that the cells generated are obtained from vascular endothelial cells, i.e. from adult cells, means that this type of therapy, for the moment, would show no objective ethical difficulties.
