A scientist revisits the atrophy-hypertrophy complex: hepatic apoptosis and regeneration

In 1898, Cantlie demonstrated his deep insight into the AHC when he wrote. "It is theoretically possible to tie the vessels of one side at the gate of the liver...leaving the other side to do the work. That one-half of the liver can hypertrophy, so as to perform the function of the whole, is attested by pathological study...I commend this subject to all those who are working on the surgery of the liver; and I believe that if, in the hands of future observers, the statements I have made receive closer investigation, surgery of the liver will be advanced a step." More than 100 years later, his foresight is coming to fruition, but the understanding of the AHC remains rudimentary. Further insight into the cellular and molecular mechanisms that initiate hepatocyte replication after contralateral atrophy may allow the development of novel therapeutic treatments or adjuncts.
