Step 1: iPSC/ESC maintainance
day 0 ~ 5
culture “spheroid” human ESC in “unspecified medium” for “5” days. Medium should be changed once in “5” days.
Step 2: mesoderm 1
day 5 ~ 6
culture “spheroid” human ESC in “unspecified medium” for “1” days. Medium should contain factors shown in the following table, and should be changed once in “1” days.
| concentration | unit | |
|---|---|---|
| CHIR90021 | 1.2e-5 | mol/l |
Step 3: mesoderm 2
day 6 ~ 8
culture “spheroid” human ESC in “unspecified medium” for “2” days. Medium should contain factors shown in the following table, and should be changed once in “2” days.
| concentration | unit | |
|---|---|---|
| IWP2 | 5.0e-6 | mol/l |
Ideally, “CPC” should express “NKX2.5”, “ADGRL2”, “ISL1” at the end of culture.
Step 4: endothelial 1
day 8 ~ 10
culture “adherent” human CPC in “DMEM/F12” 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 | |
|---|---|---|
| B27 | 2 | % |
| Glutamine | 0.002 | mol/l |
| NEAA | 1 | % |
| 2-mercaptoethanol | 1.0e-4 | mol/l |
| VEGF | 5.0e-5 | g/l |
| FGF | 1.0e-5 | g/l |
Ideally, “EC” should express “PECAM1”, “KDR”, “VWF” at the end of culture.
