Volumetric DNA microscopy for mapping spatial transcriptomes in three dimensions Nature Protocols, Published online: 24 February 2026; doi:10.1038/s41596-025-01329-3This protocol for encoding spatial information via DNA sequences enables template-free reconstruction of three-dimensional gene expression patterns in intact specimens, thereby overcoming the limitations of two-dimensional spatial imaging. http://dlvr.it/TR8GV8
