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 “3” “%”. Medium should contain factors shown in the following table.
| concentration | unit | |
|---|---|---|
| Y27632 | 1.0e-5 | mol/l |
Ideally, “PSC” should be obtained at the end of culture.
Step 2: Primitive streak 1
day 1 ~ 3
culture “adherent” human PSC in “RPMI” for “2” days. For ECM, use “Matrigel” at “3” “%”. Medium should contain factors shown in the following table, and should be changed once in “2” days.
| concentration | unit | |
|---|---|---|
| CHIR90021 | 1.2e-5 | mol/l |
Step 3: mesoderm 1
day 3 ~ 5
culture “adherent” human PSC in “RPMI” for “2” days. For ECM, use “Matrigel” at “3” “%”. Medium should contain factors shown in the following table, and should be changed once in “2” days.
| concentration | unit | |
|---|---|---|
| B27 | — | — |
Step 4: endothelial 1
day 5 ~ 11
culture “device” human PSC in “RPMI 1640” for “6” days. For ECM, use “Matrigel” at “1.5” “%”. Medium should contain factors shown in the following table, and should be changed once in “6” days.
| concentration | unit | |
|---|---|---|
| VEGF | 1.0e-4 | g/l |
| Glutamine | 1 | % |
| B27 | — | — |
Ideally, “EC” should express “PECAM1” at the end of culture.
