While organoids aim to mimic human organs, the liver's repertoire of complex functions – and thus the energy it needs to operate – have made it challenging for researchers to grow organoids that proliferate and fully function, says Sato. When prioritizing growth and survival in laboratory settings, hepatocytes, the liver's main cells, eventually transformed into cells resembling cholangiocytes, which line the bile duct. Hepatocyte functions only lasted 1-2 weeks at most.
Scientists achieve record-breaking growth in miniature, functional liver models
