From: Gating of miRNA movement at defined cell-cell interfaces governs their impact as positional signals
Schematic representation of polarised gate-keepers regulating the cell-to-cell movement of miRNAs. a Polarisation of factors that block miRNA mobility to defined cell–cell interfaces can establish unidirectional movement between neighbouring cells, or b when polarised to both sides of select interphases between multiple adjacent cells create domains with confined miRNA mobility. Blue arrows, miRNA movement; red line, polarised inhibition of miRNA movement; pink shading, miRNA mobility domain
