Abstract:
Microscopy advancements enable real-time imaging and analysis of cancer spheroids embedded in atelocollagen gel. Here, we present a protocol for extracting high-quality total RNA from 3D tumor spheroids embedded in atelocollagen gel, including spheroids and invading cells dispersed into surrounding gel. We describe steps for spheroid formation, gel embedding, live-cell imaging, and image analysis. We then detail procedures for collecting sufficient quantities of total RNA suitable for comprehensive transcriptome analysis. This approach advances transcriptome profiling in diverse 3D cultured samples.
