Organoids - a new research tool .
Full article can be found here .
Most of the research behind new medical advances is carried out using
either animal tissues or cancer cells. Both tools have their problems:
results from animals and humans do not always match up and cancer cells
grown for years in laboratories often do not mimic the tissues they
originally came from very well. Bridging the gap between whole animals
and simple cells can be a challenge during the development of new
treatments, but this is beginning to change since scientists have learned
how to grow organoids.
Organoids are clusters of cells that organise themselves into mini versions
of our organs. They are grown from stem cells, which has only become
possible with the discovery of the precise conditions needed to keep stem
cells alive outside the body. Organoids were first made from intestines but
have since been made for many other tissues, including liver, breast and
even brain cells. This will allow scientists to better study the development
and diseases of these organs.
