Spontaneously-forming spheroids as an in vitro cancer cell model for anticancer drug screening.

ABSTRACT: The limited translational value in clinic of analyses performed on 2-D cell cultures has prompted a shift toward the generation of 3-dimensional (3-D) multicellular systems. Here we present a spontaneously-forming in vitro cancer spheroid model, referred to as spheroids(MARY-X), that precisely reflects the pathophysiological features commonly found in tumor tissues and the lymphovascular embolus. In addition, we have developed a rapid, inexpensive means to evaluate response following drug treatment where spheroid dissolution indices from brightfield image analyses are used to construct dose-response curves resulting in relevant IC50 values. Using the spheroids(MARY-X) model, we demonstrate the unique ability of a new class of molecules, containing the caged Garcinia xanthone (CGX) motif, t
