Use of GelMA for 3D printing of cardiac myocytes and fibroblasts

In this Research Article from the Journal of 3D Printing in Medicine, the authors compare the effect of the 3D printing process on two different types of cardiac cells: cardiac myocytes and fibroblasts.  Keywords: bioluminescence imaging • cardiac fibroblasts • cardiomyocytescell viability • 3D bioprinting • GelMA Aim: To 3D print heart tissue, one must understand how the main two types of cardiac cells are affected by the printing process. Materials & methods: Effects of gelatin methacryloyl (GelMA) concentration, extruder pressure and duration of UV exposure on survival of cardiac myocytes and fibroblasts were examined using lactate dehydrogenase and LIVE/DEAD assays, bioluminescence imaging and...
