[Our lab uses] a desktop inkjet printer, but instead of using ink, we're using cells.
Every 30 seconds a patient dies from diseases that could be treated with tissue replacement.
When a patient does get an organ from another person, it comes from a different body. It has different properties, and a persons natural tendency is to reject that organ.
Building a solid organ like the liver in the lab is different and harder than with an organ like the bladder because solid organs are very vascular.
