Step 1: iPSC/ESC maintainance
day 0 ~ 1
culture “adherent” human PSC in “mTeSR” for “1” days. For ECM, use “Matrigel” at “0.083” “g/l”. Medium should be changed once in “1” days.
Ideally, “PSC” should be obtained at the end of culture.
Step 2: mesoderm 1
day 1 ~ 2
culture “adherent” human PSC in “DMEM/F12” for “1” days. For ECM, use “Matrigel” at “0.083” “g/l”. Medium should contain factors shown in the following table, and should be changed once in “1” days.
| concentration | unit | |
|---|---|---|
| KSR | 20 | % |
| NEAA | 1 | % |
| GlutaMAX | 0.5 | % |
| 2-mercaptoethanol | 8.4e-7 | mol/l |
Step 3: endothelial 1
day 2 ~ 3
culture “adherent” human PSC in “Endothelial cell serum-free medium” for “1” days. For ECM, use “Matrigel” at “0.083” “g/l”. Medium should contain factors shown in the following table, and should be changed once in “1” days.
| concentration | unit | |
|---|---|---|
| human serum | 1 | % |
| FGF | 2.0e-6 | g/l |
| retinoic acid | 1.0e-5 | mol/l |
Ideally, “EC” should express “PECAM1”, “GLUT-1” at the end of culture.
Step 4: endothelial 2
day 3 ~ 4
culture “adherent” human EC in “Endothelial cell serum-free medium” for “1” days. For ECM, use “collagen IV + fibronectin” at “0.05” “g/l”. Medium should contain factors shown in the following table, and should be changed once in “1” days.
| concentration | unit | |
|---|---|---|
| human serum | 1 | % |
| FGF | 2.0e-6 | g/l |
| retinoic acid | 1.0e-5 | mol/l |
| PSA | 1 | % |
| Y27632 | 1.0e-5 | mol/l |
Ideally, “EC” should express “PECAM1”, “GLUT-1”, “claudin-5”, “CDH5”, “ZO1”, “occludin”, “P-glycoprotein”, “KDR”, “IL4R”, “CCR1”, “CXCR4”, “IL17RD”, “CXCL12” at the end of culture.
