Methods for acquiring spatially resolved omics data from complex tissues use barcoded DNA arrays of low- to sub-micrometer features to achieve single-cell resolution. However, fabricating such arrays (randomly assembled beads, DNA nanoballs or clusters) requires sequencing barcodes in each array, limiting cost-effectiveness and throughput. Here, we describe a vastly scalable stamping method to fabricate polony gels, arrays of ~1-micrometer clonal DNA clusters bearing unique barcodes. By enabling repeatable enzymatic replication of barcode patterned gels, this method, compared with the sequencing-dependent array fabrication, reduced cost by at least 35-fold and time to approximately 7 hours. The gel stamping was implemented with a simple robotic arm and off-the-shelf reagents. We leveraged the resolution and RNA capture efficiency of polony gels to develop Pixel-seq, a single-cell spatial transcriptomic assay, and applied it to map the mouse parabrachial nucleus and analyze changes in neuropathic pain-regulated transcriptomes and cell-cell communication after nerve ligation. Polony gels, arrays of micron-scale DNA clusters bearing unique barcodes, enable repeatable, gel-to-gel array replication and in situ capture of tissue RNAs with high resolution and efficiency. Pixel-seq, a polony gel-based, single-cell spatial transcriptomic assay, reveals neuronal and glial heterogeneity and chronic pain-induced changes in the mouse parabrachial nucleus.
