Generation of neighbor-labeling cells to study intercellular interactions in vivo.

ABSTRACT: Understanding cell-cell interactions is critical in most, if not all, research fields in biology. Nevertheless, studying intercellular crosstalk in vivo remains a relevant challenge, due mainly to the difficulty in spatially locating the surroundings of particular cells in the tissue. Cherry-niche is a powerful new method that enables cells expressing a fluorescent protein to label their surrounding cells, facilitating their specific isolation from the whole tissue as live cells. We previously applied Cherry-niche in cancer research to study the tumor microenvironment (TME) in metastasis. Here we describe how to generate cancer cells with the ability to label their neighboring cells (within the tumor niche) by transferring a liposoluble fluorescent protein. Live niche cells can be isolated
