Extracellular lipidosomes are taken up by non-migrating and migrating cells. A, B FEMX-I cells growing on fibronectin-coated supports were recorded in live by phase-contrast/fluorescence video microscopy after staining with LipidSpotâ„¢ 610. Non-migrating (A) and migrating (B, arrow) cells can uptake an extracellular lipidosome (asterisk). The latter can be detected inside the recipient cells (A, arrowhead). Elapsed time in minutes is shown on the top-right corner. The images are excerpted from the Additional file 9: Video S8 (A) and Additional file 10: Video S9 (B). Scale bars are indicated
