Top: scratch wound assay generates a free edge on a confluent monolayer of HUVECs and encourages cell migration. Bottom: smFISH co‐detection of RAB13 mRNA and GAPDH mRNA in representative HUVECs migrating in a scratch wound assay. ZO‐1 immunolabelling defines cell boundaries.

Polarisation Index of RAB13 and GAPDH co‐detected in HUVECs cultured in scratch wound assays (n ≥ 28 cells; *P < 0.05, ns: not significant; Mann–Whitney test).

Quantification of the number of RAB13 mRNA smFISH spots per cell (n ≥ 28 cells; ***P < 0.001; Mann–Whitney test). Leader: cells identified at the edge of the scratch; follower: cells identified in confluent regions adjacent to leader cells.

Data information: arrows indicate orientation of RNA localisation; yellow dashed lines outline cell borders; red circles highlight smFISH spots; scale bars = 20 μm (A). Bar charts are presented as means ± s.d.
