Abstract: Substrates and methods for spatially resolved analyses of tissue samples are provided, allowing the data from such analyses to be mapped back to the tissue's initial architecture. For analyses that have previously been conducted on bulk, homogenized samples or on dissociated cell components not directly traceable to their prior positions in the tissue sample, spatial resolution of this data can allow better characterization of cell-cell and cell-microenvironment relationships and interactions. This spatial context can aid in determining structure-function relationships in healthy and diseased tissues may thereby enhance the scientific understanding of tissue homeostasis, development, disease, and repair. The information determined using the methods of the disclosure can also be applied to enhancing diagnostics evaluation of diseased tissues.

Abstract: A stamp and a method for transferring particles to cells of a cell culture. The stamp includes a body having upper and lower surfaces. The lower surface includes a recessed portion. A gel extends along the recessed portion of the lower surface of the body and including the particles patterned therein. The body is configured to move between a first position wherein the gel is isolated from the cells of the cell culture and a second position wherein the particles patterned in the gel communicate with the cells of the cell culture through diffusion.
