Step 1: iPSC/ESC maintainance
day 0 ~ 1 (duration missing in database; assumed 1 day)
culture “adherent” human ESC in “E8”. For ECM, use “Matrigel” at “N/A” “N/A”. Medium should contain factors shown in the following table.
| concentration | unit | |
|---|---|---|
| EDTA | 5.0e-4 | mol/l |
Step 2: mesoderm 1
day 1 ~ 3
culture “adherent” human ESC 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 | |
|---|---|---|
| BMP4 | 5.0e-6 | g/l |
| Activin A | 2.5e-5 | g/l |
| CHIR90021 | 1.0e-6 | mol/l |
| WNT7A | 5.0e-4 | g/l |
| GABA | 5.0e-6 | mol/l |
| Y27632 | 1.0e-5 | mol/l |
Step 3: endothelial 1
day 3 ~ 6
culture “adherent” human ESC in “E6 medium” for “3” 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 “3” days.
| concentration | unit | |
|---|---|---|
| SB431542 | 5.0e-6 | mol/l |
| VEGF | 5.0e-5 | g/l |
| WNT7A | 5.0e-4 | g/l |
| GABA | 5.0e-6 | mol/l |
| BMP4 | 5.0e-5 | g/l |
| FGF | 1.0e-4 | g/l |
Ideally, “EC” should express “PECAM1”, “CDH5”, “VWF”, “GABRB3”, “GABA”, “NKX2.1”, “CXCR4” at the end of culture.
Step 4: endothelial 2
day 6 ~ 8
culture “adherent” human ESC in “E6 medium” 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 | |
|---|---|---|
| VEGF | 5.0e-5 | g/l |
| FGF | 1.0e-4 | g/l |
| GABA | 5.0e-6 | mol/l |
Ideally, “EC” should express “PECAM1”, “VWF”, “GABRB3”, “CDH5”, “NKX2.1”, “PAX6”, “ISL1”, “GABA”, “CXCR4” at the end of culture.
