Beyond Spatial Transcriptomics: Tissue Systems Biology

An increasing number of technologies combine spatial discrimination with molecule identification, as has been done for decades through immunohistochemistry and in situ hybridization. The difference is that now a sleuth of commercially available platforms promises to significantly increase the number of targets that can be identified on a single sample. They also provide higher throughput in terms of number of samples that can be interrogated, and some offer semi-automation with straightforward sample preparation. All of these characteristics set up the new spatial profiling technologies as attractive candidates for biomedical research facilities. However, to be able to discriminate between them it is necessary to share real world experiences using them in our cores. This panel session brings together several researchers with hands on experience using two or more spatial profiling technologies. These will include antibody based (Opal/Vectra Polaris, Ultivue, MIBI, Hyperion) and nucleic acid (Visium, GeoMx) based platforms. Each panelist will give a quick overview of the technology, its biochemical principles, costs, advantages and disadvantages as they have identified them and compared them to each other or a gold standard, if available. At the end, we will have an open discussion where the audience is encouraged to ask questions and provide their experiences.
