Step 1: iPSC/ESC maintainance
day 0 ~ 1 (duration missing in database; assumed 1 day)
culture “adherent” human PSC in “unspecified medium”. For ECM, use “FN1” at “0.01” “g/m2”. Medium should contain factors shown in the following table.
| concentration | unit | |
|---|---|---|
| collagenase IV | — | — |
Step 2: mesoderm 1
day 1 ~ 11
culture “adherent” unknown species PSC in “unspecified medium” for “10” days. For ECM, use “FN1” at “0.01” “g/m2”. Medium should be changed once in “10” days.
Ideally, “EPC” should express “PECAM1”, “KDR”, “GLUT-1”, “CLAUDIN-5”, “OCCLUDIN” at the end of culture.
Step 3: mesoderm 2
day 11 ~ 12 (duration missing in database; assumed 1 day)
culture “adherent” human EPC in “EGM2”. For ECM, use “FN1” at “0.01” “g/m2”. Medium should contain factors shown in the following table.
| concentration | unit | |
|---|---|---|
| SB431542 | 1.0e-5 | mol/l |
| FGF | 1.0e-6 | g/l |
| VEGF | 5.0e-5 | g/l |
Step 4: endothelial 1
day 12 ~ 27
culture “adherent” unknown species EPC in “EGM2” for “15” days. For ECM, use “FN1” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “15” days.
| concentration | unit | |
|---|---|---|
| SB431542 | 1.0e-5 | mol/l |
| FGF | 1.0e-6 | g/l |
| VEGF | 2.5e-5 | g/l |
| Wnt3a | 1.0e-5 | g/l |
| retinoic acid | 1.0e-5 | mol/l |
Ideally, “EC” should express “VE-CADHERIN”, “CLAUDIN-5”, “ZO-1”, “OCCLUDIN”, “GLUT-1”, “PECAM1”, “TIE-2”, “VWF”, “CLDN1”, “ZO1”, “SLC16A1”, “INSR”, “TFRC”, “LRP1”, “ABCB1”, “ABCC1”, “ABCC5”, “PGP” at the end of culture.
