To use tumor spheroids in an HT format, we developed a simple protocol for rapid production of homogenous multicellu-lar tumor spheroids even from aggregate-forming cell types. In Webb13 aug. 2024 · We employed the 3D cell culture chip (hereafter will be referred to as ‘3D chip’) to conduct spheroid drug sensitivity assays. The 3D chip is amenable to test multiple cancer cell lines, subjected to different drug combinations and concentrations. The spheroids are embedded in collagen matrix, recapitulating the tumour microenvironment … cuba ballet school

WebbHeLa cellular spheroids (perfectly) and monolayer cells (dissociated) were collected for sample preparation. Primary fixation was done with 3% glutaraldehyde followed by secondary fixation with 1% osmium tetroxide in dark for 2 hours at room temperature. The flat layers and spheroids were suspended in 2% molten agar to make small blocks.
