Abstract:
Cell culture system is used for a wide range of research and biotechnology production. Majority of in vitro cell studies are conducted as static, two dimensional (2D) dish culture system where cells grow in a monolayer. However, to better reflect the in vivo condition, three dimensional (3D) culture systems were introduced that allow investigating the cell–cell and cell–microenvironment interactions. In this work, the 3D breast cancer model was investigated. Previously, we developed a 3D breast cancer model that constituted of fibroblasts and breast cancer cells seeded on the silkworm silk scaffold. The dynamic culture condition that provides the medium flow and shear forces was implemented to the model. The dynamic conditions were compared to the static cultivation regarding its influence on the number of cells, their viability, scaffold penetration, and cells co‐localization. The implication of the dynamic condition to the 3D cultures resulted in a higher number and viability of the cells compared with the static 3D cultures. In contrast to the static culture condition, during the dynamic cultivation cells penetrated entirely and evenly the inner parts of the scaffold. Moreover, in coculture, the transitions like a ratio of fibroblast to the cancer cells, fibroblast morphology, and their localization were similar in both types of culture conditions, but they proceeded much faster during the dynamic cultivation. The implementation of dynamic culture condition shortened the time needed to establish the settle 3D breast cancer model. The established dynamic cancer model can be used to study tumor biology and drug screening.
