“…Several remarkable methodologies have been recently developed that allow spatially resolved transcriptomic profiling of tissue sections. They can be divided in three main classes based on their detection method: physical segmentation using microdissection coupled to sequencing (Nichterwitz et al, 2016;Peng et al, 2019), pre-designed probes for either single-molecule hybridization (Eng et al, 2019;Zhuang, 2021) or amplification and in situ decoding (Alon et al, 2021;Lee et al, 2014;Wang et al, 2018), and barcoded probes (Cho et al, 2021a;Rodriques et al, 2019;Srivatsan et al, 2021;Stahl et al, 2016;Vickovic et al, 2019;Yao et al, 2020). These techniques all have specific advantages and disadvantages in resolution and applicability but share a major caveat in the limited field of view.…”
