The human liver has some amazing regenerative properties. As much as a third of it can be removed, and it can regenerate to perfect function. Scientists have tried to make use of this for the growth of livers outside of the body for a long time, but for some reason, they liver cells would no longer reproduce outside of the body. Recently (yesterday), scientists published an article saying that they have now identified 12 different chemicals that make the liver cells continue to regenerate and grow outside of the body. This is a major step in the progress toward not only externally grown livers, but all externally grown organs.
Nature of science themes:
- Science is collaborative: Dr. Bhatia as well as a team of scientists from MIT discovered this, but their work was built on the work of the many scientists before them who were all trying to solve the same problem.
-Science is based on evidence: The liver cells in the new substances when put in a pitri dish were shown to start regenerating, unlike those in any other solutions or in no solution at all.
-Roll of motivation and curiosity: The students wouldn't have gone to MIT for medicinal research if they weren't interested. They also know that this will help a lot of people. Just to give an example, I heard that someone at EPHS recently had a liver transplant, and were very lucky to have gotten one. If this technology becomes successful in the future, getting a liver will never be a problem.
-Importance of repeatability: Obviously if this can't be repeated, then the experiment is useless, as the end goal is the have a reliable way to generate organs for people who need transplants.

That's a neat article and a great step toward getting artificial livers made. I've always been interested in organ transplant and it's good to know that lives may be saved from this research.
ReplyDeleteActually a year ago I came across this page;

I found it really touching and that's when I started doing some research on living liver transplantation...it's a super complicated process but it's so cool that it's actually possible!
