Fig. 4.

Both ACs and ACPCs produce PCM and ECM components, but there are differences in structure and production rates by individual cells. Representative fluorescence microscopy images of ACs (A-D) and ACPCs (E-H) in agarose microgels showing the presence of PCM and ECM components at days 0, 3, 5, and 10. Tiles show DAPI (cyan) with either type-VI collagen (green), perlecan (violet), type-II collagen (red), or a merged view of all four channels. Scale bar = 50 µm.
