Organ transplants have always been a tricky business, first you have to find a viable match for the person who needs it and then there is always the chance of rejection. Scientists have dreamed of building organs in a lab but generating the structure of a working organ has always been a tricky prospect. However due to a recent study at Harvard this dream is becoming more real. Scientists have successfully stripped a cadaver rat kidney of all native cells leaving only and cellular matrix of the kidney and have successfully implanted the
hosts cells and grew an functional kidney which was later successfully implanted in the host rat.
