Step 1: iPSC/ESC maintainance
day 0 ~ 3
culture “adherent” human PSC in “mTeSR” for “3” days. For ECM, use “Matrigel” at “0.2” “g/m2”. Medium should contain factors shown in the following table, and should be changed once in “3” days.
| concentration | unit | |
|---|---|---|
| PSA | 0.5 | % |
| Dispase | 1 | g/l |
Ideally, “PSC” should be obtained at the end of culture.
Step 2: mesoderm 1
day 3 ~ 5
culture “adherent” human PSC in “BPEL” for “2” days. For ECM, use “Matrigel” at “0.2” “g/m2”. Medium should contain factors shown in the following table, and should be changed once in “2” days.
| concentration | unit | |
|---|---|---|
| BMP4 | 3.0e-5 | g/l |
| Activin A | 2.5e-5 | g/l |
| CHIR | 1.5e-6 | mol/l |
| VEGF | 5.0e-5 | g/l |
| BSA | 0.25 | % |
| Lipids | 0.1 | x |
| ITS | 1 | x |
| MTG | 4.5e-4 | mol/l |
| Ascorbic Acid | 0.05 | g/l |
| GlutaMAX | 0.002 | mol/l |
| PSA | 0.5 | % |
| PFHMII | 5 | % |
Ideally, “mesoderm” should be obtained at the end of culture.
Step 3: endothelial 1
day 5 ~ 9
culture “adherent” human PSC in “BPEL” for “4” days. For ECM, use “Matrigel” at “0.2” “g/m2”. Medium should contain factors shown in the following table, and should be changed once in “4” days.
| concentration | unit | |
|---|---|---|
| VEGF | 5.0e-5 | g/l |
| SB431542 | 1.0e-5 | mol/l |
| BSA | 0.25 | % |
| Lipids | 0.1 | x |
| ITS | 1 | x |
| MTG | 4.5e-4 | mol/l |
| Ascorbic Acid | 0.05 | g/l |
| GlutaMAX | 0.002 | mol/l |
| PSA | 0.5 | % |
| PFHMII | 5 | % |
Ideally, “EC” should express “CDH5”, “PECAM1”, “VWF” at the end of culture.
Step 4: endothelial 2
day 9 ~ 11
culture “adherent” human PSC in “BPEL” for “2” days. For ECM, use “Matrigel” at “0.2” “g/m2”. 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 |
| SB431542 | 1.0e-5 | mol/l |
| BSA | 0.25 | % |
| Lipids | 0.1 | x |
| ITS | 1 | x |
| MTG | 4.5e-4 | mol/l |
| Ascorbic Acid | 0.05 | g/l |
| GlutaMAX | 0.002 | mol/l |
| PSA | 0.5 | % |
| PFHMII | 5 | % |
Ideally, “EC” should express “CDH5”, “PECAM1” at the end of culture.
