Bone marrow-on-a-chip models damage and disease

Recently, I blogged here about body-on-a-chip!  Now, a new organ-on-a chip has been reported! Amazing stuff!

"Until David Chou, Viktoras Frismantas and their colleagues developed the bone marrow chip, the only way to study living marrow tissue effectively was to take painful biopsies from the bones. ... we are in a position to assist in the design of human clinical trials for rare genetic disorders and advance personalized medicine in ways not possible before"
