Figure 4.
Aggregation and adhesion of retinal progenitor cells (RPCs). Images of RPCs at a cell density of 105 cells/mL adhered as individual cells and neuroclusters upon surfaces of: (a) poly-l-lysine (PLL), (b) fibronectin (FN), (c) laminin (LM), (d) hyaluronic acid (HA), and (e) Matrigel (MG). Representative cell clusters are outlined per image and arrows point to individually adhered cells. Scale bar = 200 µm. Representative images of RPCs evaluated as (f, g) individually adhered cells, (h) RPCs adhered with close adhesion spacing but not as neuroclusters, and (i) RPCs adhered as part of neuroclusters. Scale bar = 20 µm.
