Step 1: iPSC/ESC maintainance
day 0 ~ 1 (duration missing in database; assumed 1 day)
culture “unspecified method” human PSC in “E8”. For ECM, use “kidney dECM” at “N/A” “N/A”. Medium should contain factors shown in the following table.
| concentration | unit | |
|---|---|---|
| Y27632 | — | — |
Ideally, “PSC” should be obtained at the end of culture.
Step 2: mesoderm 1
day 1 ~ 4
culture “unspecified method” human PSC in “APEL2 medium” for “3” days. For ECM, use “kidney dECM” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “3” days.
| concentration | unit | |
|---|---|---|
| CHIR90021 | 1.5e-6 | mol/l |
| BMP4 | 3.0e-5 | g/l |
| ACTIVIN A | 2.5e-5 | g/l |
| PFHMII | — | — |
Ideally, “mesoderm” should be obtained at the end of culture.
Step 3: endothelial 1
day 4 ~ 11
culture “unspecified method” human PSC in “APEL2 medium” for “7” days. For ECM, use “kidney dECM” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “7” days.
| concentration | unit | |
|---|---|---|
| SB431542 | 1.0e-5 | mol/l |
| PFHMII | — | — |
Ideally, “EC” should express “VE-CADHERIN”, “PECAM1” at the end of culture.
