3D CULTIVATION OF PANCREAS CARCINOMA CELL LINES FOR DRUG SCREENING
Abstract
Abstract Body
Cells develop in a 3D environment having interactions with ECM and other cells. 3D culturing facilitates differentiation and organization, using micro-structures mimicking in vivo interactions. 3D culturing is used in medical fields, from drug screenings to printing implants.
Aims: (1) to create 3D pancreatic tumor spheroids by magnetic bioprinting and characterize their morphology. (2) to test their behavior after drug treatment and determining IC50 values (3) comer the results of 2D and 3D cultures.
Methods: Two pancreatic adenocarcinoma cell lines, PANC1 and MIAPaCa2, were printed by magnetic bioprinting into 3D spheroids. The spheroid morphology was evaluated in Celldiscoverer7 (Zeiss), while viability determined by Cell Titer Glo assay and xCELLigence system. We tested 6 conventional chemotherapy compounds (e.g., tamoxifen, TIC10, and LCL161) and their novel derivatives.
Results: Both cell lines formed spheroids. Gemcitabine, the widely used anti-tumor agent in pancreas tumor management, showed decreased viability. SMAC mimetic had a spectrum of IC50 values, for LCL161 and another derivative tested of the IC50 was less than 1.85 µM. TIC10 and its derivative and the TMX derivative had very influential results as well. TMX showed the biggest difference between the two culturing techniques; it did not influence the 3D cultures while affecting the 2D cultures.
Conclusion: The 3D culture established by magnetic bioprinting mimics the in vivo cell conditions. the drug treatments on both culturing techniques show similarities in influence, but the degree was different. The novel derivatives tested showed a remarked influence and should be further researched.
