A key goal of biology is to relate the expression of specific
genes to a particular cellular phenotype. However, current assaysfor
gene expression destroy the structural context. By combiningadvances
in computational fluorescence microscopy with multiplexprobe design,
we devised technology in which the expression ofmany genes can be
visualized simultaneously inside single cellswith high spatial and
temporal resolution. Analysis of 11 genesin serum-stimulated cultured
cells revealed unique patterns ofgene expression within individual
cells. Using the nucleus asthe substrate for parallel gene analysis,
we provide a platformfor the fusion of genomics and cell biology:
"cellular genomics."
