Step 1: iPSC/ESC maintainance
day 0 ~ 1 (duration missing in database; assumed 1 day)
culture “adherent” human PSC in “mTeSR”. For ECM, use “Matrigel” at “0.333” “g/l”.
Ideally, “PSC” should express “POU5F1”, “SSEA4”, “TRA-1-60”, “SOX2”, “ZO1”, “Occludin”, “transferrin receptor”, “P-gp” at the end of culture.
Step 2: endothelial 1
day 1 ~ 6
culture “adherent” human PSC in “DMEM/F12” for “5” days. For ECM, use “Matrigel” at “0.333” “g/l”. Medium should contain factors shown in the following table, and should be changed once in “5” days.
| concentration | unit | |
|---|---|---|
| KSR | 20 | % |
| NEAA | 1 | % |
| Glutamine | 0.5 | % |
| 2-mercaptoethanol | 8.4e-7 | mol/l |
Step 3: endothelial 2
day 6 ~ 8
culture “adherent” human PSC in “Endothelial cell serum-free medium” for “2” days. For ECM, use “Matrigel” at “0.333” “g/l”. Medium should contain factors shown in the following table, and should be changed once in “2” days.
| concentration | unit | |
|---|---|---|
| platelet-poor serum | 1 | % |
| FGF | 2.0e-5 | g/l |
| retinoic acid | 1.0e-5 | mol/l |
Ideally, “EC” should express “ABCB1”, “ABCC1”, “ABCG2”, “SLC2A1”, “TRFC”, “ZO1”, “Occludin”, “Claudin5”, “Glut1”, “insulin receptor”, “LDL receptor”, “PECAM1”, “VWF”, “P-gp” at the end of culture.
