What will they think of next?

In keeping with my earlier post about what my young cousin may see in the next 89 years, I give you, "Printing Organs on Demand?"

According to MU, “the team used bio-ink particles, or spheres containing 10,000 to 40,000 cells, and assembled, or ‘printed,’ them on to sheets of organic, cell friendly ‘bio-paper.’ Once printed, the spheres began to fuse in the bio-paper into one structure.” Nature adds that “when they printed out cardiac and endothelial cells, the cells fused into a tissue after 70 hours, and began beating in time like regular heart tissue after 90 hours.”

Maybe they can do something with knees...
