Printability Optimization of Gelatin-Alginate Bioinks by Cellulose Nanofiber Modification for Potential Meniscus Bioprinting

Figure 5

Viability and metabolic activity of bioprinted samples. (a) Live/dead staining of rFCs immediately at 1, 4, 7, and 14 d of culturing in vitro. Living cells are stained green and dead cells red. Scale bar 100 μm. (b) Quantitative statistics of the bioprinted samples at different time points using ImageJ. (c) Metabolic activity values of bioprinted rFCs using an alamar blue assay at different time points.
