Fig. 4. Label-retaining interstitial stem cells localize close to the extracellular matrix.

Localization of GFP (red), laminin (green) and EdU-retaining cells (yellow) in cnnos1::GFP lines at one week of chase. Nuclei are stained with DAPI (blue). The label-retaining interstitial stem cells localize close to the extracellular matrix and are marked with arrows while those with partial label are marked with asterisks. Scale bars: 10 µm. Individual images of each fluorophore are shown in supplementary material Fig. S4A,B.
