Liver cells are versatile workhorses, synthesizing key proteins while clearing toxins from the body. But these homebodies rarely survive outside the liver, making them challenging to study. Asli Unal, a graduate student in Jennifer West’s lab, is building synthetic homes for picky liver cells. In this Mahato-winning image, she has mixed liver cells (green) and blood cells (red) into a specially-designed jello-like substance which allows them to grow and build their own “extracellular matrix” – essentially redecorating so they feel more at home. By helping liver cells survive outside the body, she hopes to give researchers better ways to study and treat liver disease.
