Figure 1.

Heterogeneous morphologies of corneal stroma cells seeded at different densities. At 5 cells/mm², cell morphologies included dendritic (arrows), stellate, small polyhedral, and neuronlike cells (A). A similar finding of neuronlike cells was seen at 50 cells/mm² (B, arrows). At 500 cells/mm², cells were polyhedral and formed a confluent monolayer with neuronlike cells (C, arrows). The observed heterogeneity was also seen among neuronlike cells. Cell groups had similar morphologies with multiple dendritic processes that suggested a common origin (D) or different morphologies containing both multiple and bipolar dendritic processes (E). Most of the neuronlike cells were found as single cells (F). Bar, 25 μm.
