dc.description.abstractIntroduction and objective: Cancer is currently one of the leading causes of death in the world. The objective of this work is the formation of viable spheroids from cells of melanoma (SKMEL-37) and colon adenocarcinoma (HT29-MTX) cell lines and their evaluation regarding cell viability to enable the use of threedimensional cell culture as an alternative to the use of experimental animal models. Methodology: Cells were maintained in RPMI 1640 medium and kept in an incubator at 37°C, 5% CO₂ with controlled humidity. Upon reaching 60-70% confluence, cells were washed with phosphate buffered saline (PBS) and detached using trypsin solution. Afterwards, they were seeded in 24-well plates pre-treated with PluronicⓇ F-127 (0.5g/mL in 2-propanol) and turned back in incubator for 72 hours. Then, the formed spheroids were stained with Hoechst 33342 and SYTOX® Green solution, incubated for 60 minutes and images were acquired automatically in a HTS equipment (INCell 2500 HS, Cytiva). Results and discussion: Properly cohesive spheroids were obtained for both lineages, 20-30 per well. After 72h, only a small fraction of cells (about 5%) were considered unviable by SYTOX® staining. Principal Component Analysis (PCA) using 13 variables, and further Principal Component Regression (PCR) showed that nuclei mean and maximum intensities (Hoechst), and nuclei volume are the most relevant variables, corelated to number of plated cells. Days in culture appeared to not correlate with other variables. Conclusions: It was concluded that the methodology for the production of spheroids for melanoma and colon adenocarcinoma cell lines presented is simple, fast and cheap, in which, in 72 hours, the spheroids form freely, without restriction of shape and size and presenting low cell death, being also compatible with the high throughput screening technique (HTS). Nuclei volume and intensity can be used in future analysis to assess cell global viability in spheroids.
