Figure 5. The effect of photoreceptor cell conditioned medium on microglial expression of chemokines and noxious factors

A: Representative gel images showed the indicated RT-PCR products at 12 h after treatment with 661W cell conditioned medium with or without photic injury. B: Quantification of changes in mRNA expression. The relative mRNA levels were normalized to β-actin. *p<0.01 versus cells grown in basal medium (NC). Hash mark p<0.01 versus cells grown in 661W cell conditioned medium without photic injury.
