Fibroblasts Accelerate Formation and Improve Reproducibility of 3D Cellular Structures Printed with Magnetic Assistance

Figure 2

Presence of Gd3+ during formation of 3D cellular structures via magnetic assistance. The presence of Gd3+ ions within 3D cellular structures printed with magnetic assistance is observed in the two cell lines. A higher Gd3+ concentration is observed in 3D fibroblast structures () than in the MDA-MB-231 structures (), as compared to their control samples formed through gravitational settling. Trace amounts of Gd3+ present in the control samples are attributed to instrument measurement sensitivity.
