Step 1: iPSC/ESC maintainance
day 0 ~ 1
culture “adherent” human PSC in “mTeSR” for “1” days. For ECM, use “SpGel” at “N/A” “N/A”. Medium should be changed once in “1” days.
Ideally, “PSC” should express “POU5F1” at the end of culture.
Step 2: Primitive streak 1
day 1 ~ 3
culture “adherent” human PSC in “RPMI-1640” for “2” days. For ECM, use “SpGel” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “2” days.
| concentration | unit | |
|---|---|---|
| B27 (-Insulin) | 2 | % |
| CHIR90021 | 5.0e-6 | mol/l |
Step 3: Primitive streak 2
day 3 ~ 5
culture “adherent” human PSC in “RPMI-1640” for “2” days. For ECM, use “SpGel” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “2” days.
| concentration | unit | |
|---|---|---|
| B27 (-Insulin) | 2 | % |
| CHIR90021 | 2.0e-6 | mol/l |
Step 4: mesoderm 1
day 5 ~ 8
culture “adherent” human PSC in “RPMI-1640” for “3” days. For ECM, use “SpGel” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “3” days.
| concentration | unit | |
|---|---|---|
| B27 (-Insulin) | 2 | % |
| VEGF | 5.0e-5 | g/l |
| FGF | 1.0e-5 | g/l |
| Y27632 | 1.0e-5 | mol/l |
| SB431542 | 1.0e-6 | mol/l |
Step 5: endothelial 1
day 8 ~ 15
culture “adherent” human PSC in “EGM2” for “7” days. For ECM, use “SpGel” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “7” days.
| concentration | unit | |
|---|---|---|
| FBS | 10 | % |
| VEGF | 2.5e-5 | g/l |
| FGF | 2.0e-6 | g/l |
| Y27632 | 1.0e-5 | mol/l |
| SB431542 | 1.0e-6 | mol/l |
Ideally, “EC” should express “PECAM1” at the end of culture.
