Our interpretation is that in dense cultures, cell-cell interactions are stronger and can successfully counteract the weakening of cell-matrix interactions due to simulated microgravity (Figure 6).

Growth of hNSPCs at High Cell Density in Simulated Microgravity Conditions Causes Limite... When we exposed higher density adherent hNSPC cultures to simulated microgravity, we did not observe the same results. [Extracted from the article]
