2D vs. 3D cultures

Mesenchymal stromal cells are being explored in potential therapies for tissue regeneration and repair. However, researchers are facing challenges in maintaining MSC viability when transplanted in vivo. In this study, the authors found that compared to cells cultured in 2D. MSCs cultured in 3D showed differences in cell death and autophagy related signaling and were more therapeutic effective when transplanted in a mouse model of colitis. These studies demonstrate that an important use for 3D cultures in enhancing viability of cells used in therapeutic applications.

Enhanced viability and function of mesenchymal stromal cell spheroids is mediated via autophagy induction

There are several standardized tests used to identify carcinogens, but can result in false negatives because these tests may not adequately detect metabolic conversion of chemicalsto a genotoxic and carcinogenic compound. In this latest study, 3D but not conventional 2D assays of HepG2 cells show differences in metabolic activity and genotoxic effects to the chemical urethane.These studies indicate that 3D cultures may be an important approach for testing carcinogens.
