Several technologies enable spatial transcriptomics, including Visium by 10x Genomics, Slide-seq, and MERFISH (Multiplexed Error-Robust Fluorescence In Situ Hybridization). Each of these methods has its strengths and limitations in terms of resolution, sensitivity, and throughput. For instance, Visium offers a balance between spatial resolution and the number of genes profiled, while Slide-seq provides higher spatial resolution but may be limited in the number of genes it can analyze simultaneously.
