Currently, most organs that are harvested for transplant are transported from the donor to the recipient packed in ice and must be implanted within a matter of hours. How is organ culture an improvement on this transport method?
Answer
A
Organs that are packed in ice can be damaged by frostbite during transit.
B
Cultured organs can be kept alive for several weeks before transplant.
C
Extra culture medium is easier and cheaper to transport than extra ice.
D
Organ cultures can be shipped as cargo rather than hand delivered.
Explanation
Organ culture can keep an organ viable for a longer period than storage packed in ice, which usually allows only a matter of hours before implantation. This extra time makes it easier to arrange a transplant; choice B states that cultured organs can be kept alive for several weeks.
