Figure 3. Co-culture media does not induce leakiness of the hCMEC/D3 barrier.
The effect of co-culture media on hCMEC/D3 structure and function was assessed through a FITC-D permeability coefficient assay as previously described (Figure 1). Media conditions: complete CMEC media; CMEC media without HC; CMEC media made with an RPMI base (no EBM-2); CMEC media without HC made with an RPMI base. A 30 minute treatment with mannitol (1.4 M) is included as a positive control of barrier compromise for the assay. Statistical analysis was performed with a two-tailed Student’s t-test. *p = 0.04
