Intercellular exchange of Mitochondria.

<p>To detect potential exchange of other organelles such as mitochondria between RPTECs, cells were labeled with MitoTracker® reagent which specifically labels active mitochondria <i>in-vivo</i> (green). MitoTracker labeled cells were co-cultured for 24 h together with Qtracker 605 (red) labeled cells. Mitochondria could be detected in the lumen of the TNT-like tubes in RPTEC (A). The exchange of organelles between RPTEC is shown (highlighted by white arrows). Q605 labeled cells (red arrow). MitoTracker labeled cells (green arrow). Nuclear staining (blue, To-Pro3).
