Stem cells: the new “model organism”

Abstract

Human tissue culture cells have long been a staple of molecular and cell biology research. However, although these cells are derived from humans, they have often lost considerable aspects of natural physiological function. Here we argue that combined advances in genome editing, stem cell production, and organoid derivation from stem cells represent a revolution in cell biology. These advances have important ramifications for the study of basic cell biology mechanisms, as well as for the ways in which discoveries in mechanisms are translated into understanding of disease.
