Step 1: iPSC/ESC maintainance
day 0 ~ 1 (duration missing in database; assumed 1 day)
culture “adherent” human ESC in “DMEM/F12”. Medium should contain factors shown in the following table.
| concentration | unit | |
|---|---|---|
| KSR | 15 | % |
| NEAA | 1 | % |
| PSA | 0.5 | % |
| GlutaMAX | 0.002 | mol/l |
| 2-mercaptoethanol | 1.0e-4 | mol/l |
| FGF | 4.0e-6 | g/l |
Ideally, “ESC” should be obtained at the end of culture.
Step 2: mesoderm 1
day 1 ~ 3
culture “adherent” human ESC in “RPMI” for “2” days. For ECM, use “Gelatin” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “2” days.
| concentration | unit | |
|---|---|---|
| FBS | 15 | % |
| GlutaMAX | 0.002 | mol/l |
| 2-mercaptoethanol | 1.0e-4 | mol/l |
| NEAA | 1 | % |
| PSA | 1 | % |
Step 3: endothelial 1
day 3 ~ 5
culture “adherent” human ESC in “EBM-2” 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 | |
|---|---|---|
| FBS | 5 | % |
| Hydrocortisone | 0.04 | % |
| FGF | 0.4 | % |
| VEGF | 0.1 | % |
| IGF1 | 0.1 | % |
| Ascorbic Acid | 0.1 | % |
| EGF | 0.1 | % |
| Gentamicin | 0.1 | % |
