Step 1: iPSC/ESC maintainance
day 0 ~ 2
culture “adherent” human PSC in “E8” for “2” days. For ECM, use “Matrigel” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “2” days.
| concentration | unit | |
|---|---|---|
| Y27632 | 1.0e-5 | mol/l |
| FGF | — | — |
| TGF-beta | — | — |
Ideally, “PSC” should express “POU5F1”, “NANOG” at the end of culture.
Step 2: Primitive streak 1
day 2 ~ 4
culture “adherent” human PSC in “E8” for “2” days. For ECM, use “Matrigel” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “2” days.
| concentration | unit | |
|---|---|---|
| CHIR90021 | 6.0e-6 | mol/l |
| FGF | — | — |
| TGF-beta | — | — |
Ideally, “PS” should express “TBXT” at the end of culture.
Step 3: mesoderm 1
day 4 ~ 5
culture “adherent” human PSC in “E8” for “1” days. For ECM, use “Matrigel” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “1” days.
| concentration | unit | |
|---|---|---|
| BMP4 | 1.0e-5 | g/l |
| VEGF | 5.0e-5 | g/l |
| SB431542 | 1.0e-5 | mol/l |
| FGF | — | — |
| TGF-beta | — | — |
Ideally, “EC” should express “CD34”, “PECAM1”, “CDH5”, “KDR”, “FLT1”, “ENG” at the end of culture. Ideally, “PSC” should express “POU5F1”, “NANOG” at the end of culture.
Step 4: endothelial 1
day 5 ~ 7
culture “adherent” human EC in “EGM2” for “2” days. For ECM, use “Gelatin” at “0.2” “%”. Medium should contain factors shown in the following table, and should be changed once in “2” days.
| concentration | unit | |
|---|---|---|
| Y27632 | 1.0e-5 | mol/l |
Ideally, “EC” should express “PECAM1”, “NOS3”, “CDH5”, “VWF”, “KDR” at the end of culture.
