Poster summary

In order to increase the success rates of leukemia treatments, a greater understanding of cell interactions within the bone marrow is required. 3D bioprinting offers a solution for studying the cells in vitro by printing scaffolds that mimic the internal bone structure. Our research focused on evaluating a Cellink BioX printer in order to print custom scaffolds for 3D cell culture. These can be utilized in an environment that mimics the physiological conditions of trabecular bone to study treatments. The print conditions were optimized to produce scaffolds that had porosity and structure within the range of real human trabecular bone.
