Cord blood cells can build a better human immune system into mice

Researchers have developed a new method to recreate a robust and functional human immune system in mice using mononuclear cells from the cord blood. This new kind of mice, that count with most of the human immune cell types with lower host-versus-graft disease, are a better experimental platform to study the subtle interactions between the immune system, cancer cells and the tumour microenvironment, in healthy conditions and in disease.
