High-content screening (HCS), also known as Cellomics, is a microscopy-based method to study alterations in cellular phenotypes in response to experimental manipulation or treatment. Dedicated HCS instruments, such as the Cellomics ArrayScan VTI and the Opera LX used by us, allow for high-throughput analysis of cells in 96- or 384-well plates and support unbiased and automated image acquisition and analysis. HCS is therefore particularly useful for high-throughput compound and RNAi screens.
To study neurodevelopmental phenotypes we combine HCS with cultured primary embryonic rodent neurons or iPSC-derived human neurons. We perform both RNAi screens and compound screens and have developed a dedicated image analysis pipeline to extract up to 40 HCS parameters associated with neuronal network development and connectivity.
