It has been demonstrated over the past several decades that three-dimensional (3D) cell culture provides a superior system for mimicking the in vivo environment. Historically, flat, two-dimensional (2D) monolayer cells were the only practical option available, however, they are seriously limited in their ability to recapitulate normal tissue responses because they lack tissue-specific cytoarchitecture, in vivo mechanical and biochemical cues, and cell-to-cell interactions.
Spheroids and organoids have emerged as a more physiologically relevant model for in vivo cellular responses. These more complex models improve upon cell-line and primary cell-based methods with their ability to mimic native cytoarchitecture and to display physiological attributes of the native tissue. However, they can be difficult to culture for long periods of time, while maintaining human in vivo physiological performance. In addition, they often have size and shape variability, and poor viability.
