Fig 3. Induction of BMEC-like properties of hiPS-ECs by treatment with C6CM.

Fig 3

(A) hiPS-EC monolayers were transferred onto non-cell culture (iPSEC-mono), C6-cell culture (iPSEC-C6) or C6CM (iPSEC-C6CM) in 24-well plates. Then, the TEER value of each hiPS-EC monolayer was measured at indicated days. (B) The permeability coefficient for FD was measured in hiPS-ECs before (iPSECs) and after 5-day mono-culture (iPSEC-mono), 5-day co-culture with C6 cells (iPSEC-C6) or 5-day culture in C6CM (iPSEC-C6CM). (C) Expressions of tight junction-related genes (Claudin-5, Occuludin and ZO-1) were examined in iPSECs, iPSEC-mono, iPSEC-C6 and iPSEC-C6CM. (D) Expressions of transporter genes (P-gp, Bcrp, Mrp-4 and Glut1) were examined in iPSECs, iPSEC-mono, iPSEC-C6 and iPSEC-C6CM by RT-PCR analysis. (E) The iPSEC-C6 was treated with CSA or MK571, and then the permeability coefficient for Rhodamin 123 was investigated in them. All results shown are the mean of three independent experiments with the indicated standard deviations (S.D.). * p < 0.05.
