Optical coherence tomography offers astonishing possibilities to image the complex structure of living tissue, but without providing functional information. 

The researchers propose dynamic full-field optical coherence tomography as a technique for non-invasive imaging of living, human-induced, pluripotent stem cell-derived retinal organoids. Color images are generated with an endogenous contrast related to organelle motility, with spatial resolution in the submicrometer range and temporal resolution in the millisecond range. This makes it possible to identify specific cell types in living tissue by their function.
