New bone marrow-on-a-chip can model radiotherapy damage and assess preventive measures

Engineered bone marrow grown in a novel microfluidic chip device responds to damaging radiation exposure followed by treatment with compounds that aid in blood cell recovery in a way that mimics living bone marrow. This new bone marrow-on-a-chip microdevice holds promise for testing and developing improved radiation countermeasures, as described in Tissue Engineering.
