British spelling: to make liver-like in appearance or texture, or to undergo the process of hepatization.
From hepatic- (liver) + -ise (British verb ending). This verb form emerged alongside the noun hepatisation in medical practice, standardized in British medical terminology.
The British verb 'hepatise' and American 'hepatize' show how English-speaking medical communities adopted slightly different spelling conventions, but both mean the same fascinating process of tissue becoming liver-like during disease.
