Abstract
Nanotechnology is a rapid-growing field with an extreme potential to revolutionize cancer treatments. However, despite the rapid advances, the clinical translation is still scarce. One of the main hurdles contributing for this setback is the lack of reliable in vitro models for preclinical testing capable of predicting the outcomes in an in vivo setting. In fact, the use of 2D monolayers, considered the gold-standard in vitro technique, leads to the creation of misleading data that might not be completely observed in in vivo or clinical setting. Thus, there is the need to use more complex models capable of better mimicking the tumor microenvironment. For that purpose, the development and use of multicellular tumor spheroids, three-dimensional (3D) cell cultures which recapitulate numerous aspects of the tumors, represents an advantageous approach to test the developed anticancer therapies. In this chapter, we identify and discuss the advantages of the use of these 3D cellular models compared to the 2D models and how they can be utilized to study nanoparticle-cancer cell interaction in a more reliable way to predict the treatment outcome in vivo.
