Figure 6. Treatment with 10⁻⁷ mol/l dexamethasone (DEX) for 7 days increased cross-linked actin networks formation in both normal trabecular meshwork and trabecular meshwork cells derived from POAG individuals cells. cross-linked actin networks (CLANs) were also observed in the untreated trabecular meshwork cells derived from POAG individuals (GTM) cells. Green squares indicate areas of enlargement. Nuclei were shown by DAPI staining (blue fluorescence).
