Sci. Rep. 6, 19103. 3D tumor spheroid model for in vitro therapeutic screening: a systematic approach to enhance the biological relevance of data obtained. 2016

Zanoni, M., Piccinini, F., Arienti, C., Zamagni, A., Santi, S., Polico, R., Bevilacqua, A., and Tesei, A.

Notes: The CellTiter-Glo® 3D Cell Viability Assay, Perfecta3D Assay (3Dbiomatrix, Inc.) and simple Trypan Blue exclusion were assessed for measuring cytotoxicity of A549 cell microspheroids. The authors state, “The best and most reproducible method to determine the viability of large spheroids for both chemical and for physical treatments was the CellTiter-Glo 3D Cell Viability assay…” The CellTiter-Glo® 3D Assay reported a linear relationship for spheroids that were 350–650 microns with some deviation from linear for spheroids with a diameter of 850 microns. The authors note that this could be related to physical interference with such large spheroids as well as the presence of a necrotic core in the large spheroids. The luminescence from the CellTiter-Glo® 3D Assays was measured with a GloMax® Instrument. (4642)

J. Physiol. Sci. Feb 22, Epub ahead of print. Inhibition of monocarboxylate transporter 1 suppresses the proliferation of glioblastoma stem cells. 2016

Takada, T., Takata, K. and Ashihara, E.

Notes: The glioblastoma cell lines U-251 MG (containing mutant p53) and U-87 MG (containing wildtype p53) were grown as microspheroids on ultra-low attachment 96-well plates and treated with monocarboxylate transporter (MCT) 1 inhibitors. Morphology was examined, and viability determined by transferring well contents to white 96-well plates and assaying with the CellTiter-Glo® 3D Cell Viability Assay. Luminescence was measured using a GloMax® Discover Instrument. Relative viability was compared to the same cells grown under monolayer conditions.

Notes: Normal human dermal fibroblasts were allowed to form microspheres. Eight microspheroids were seeded per well of a 24-well plate containing electrospun polyurethane. Microspheroids were also placed into wells of a standard tissue-culture-treated plate to serve as a positive control for 100% viability. Cells were cultured for 24 or 72 hours, incubated with CellTiter-Glo® 3D Reagent, and supernatants transferred to a 96-well plate for detection in a 96-well luminometer. Microspheroids cultured on the polyurethane were judged to be 95% viable. (4641)

Notes: Topoisomerase IIα was identified as an important factor for metastasis of colorectal cancer involving the wnt signaling pathway. Microspheroids of SW620 cells, generated through ultra-low attachment plates, were used in the study. Activation of the wnt pathway was monitored with a reporter assay measured with the ONE-Glo™ Luciferase Assay System. Duplicate cells were monitored for viability with the CellTiter-Glo® 3D Cell Viability Assay. An ATP-competitive, N-terminal inhibitor of topoisomerase IIα was examined for cytotoxicity to the microspheroids. Cytotoxicity was monitored from 6–72 hours of exposure to the inhibitor using the CellTox™ Green Cytotoxicity Assay. Cytotoxicity increased over time with the inhibitor, and controls were essentially unaffected. (4708)
