Step 1: iPSC/ESC maintainance
day 0 ~ 1 (duration missing in database; assumed 1 day)
culture “adherent” human PSC in “E8”. For ECM, use “Matrigel” at “2.5” “%”. Medium should contain factors shown in the following table.
| concentration | unit | |
|---|---|---|
| Y27632 | 1.0e-5 | mol/l |
Ideally, “PSC” should be obtained at the end of culture.
Step 2: Primitive streak 1
day 1 ~ 2
culture “adherent” human PSC in “RPMI1640” for “1” days. For ECM, use “Matrigel” at “2.5” “%”. Medium should contain factors shown in the following table, and should be changed once in “1” days.
| concentration | unit | |
|---|---|---|
| B27 | 2 | % |
| GlutaMAX | 0.002 | mol/l |
| Ascorbic Acid | 0.06 | g/l |
| CHIR90021 | 6.0e-6 | mol/l |
Ideally, “PS” should express “TBXT” at the end of culture.
Step 3: mesoderm 1
day 2 ~ 3
culture “adherent” human PSC in “RPMI1640” for “1” days. For ECM, use “Matrigel” at “2.5” “%”. Medium should contain factors shown in the following table, and should be changed once in “1” days.
| concentration | unit | |
|---|---|---|
| B27 | 2 | % |
| GlutaMAX | 0.002 | mol/l |
| Ascorbic Acid | 0.06 | g/l |
| VEGF | 5.0e-5 | g/l |
| FGF | 1.0e-5 | g/l |
Ideally, “HEP” should express “CDH5”, “CD34”, “PECAM1”, “KDR” at the end of culture.
Step 4: mesoderm 2
day 3 ~ 4 (duration missing in database; assumed 1 day)
culture “adherent” human PSC in “RPMI1640”. For ECM, use “Matrigel” at “2.5” “%”. Medium should contain factors shown in the following table.
| concentration | unit | |
|---|---|---|
| B27 | 2 | % |
| GlutaMAX | 0.002 | mol/l |
| Ascorbic Acid | 0.06 | g/l |
| VEGF | 5.0e-5 | g/l |
| FGF | 1.0e-5 | g/l |
| SB431542 | 1.0e-5 | mol/l |
Ideally, “HSPC” should express “CD34”, “CD43” at the end of culture.
Step 5: endothelial 1
day 4 ~ 6
culture “adherent” human HEP in “EGM” for “2” days. For ECM, use “Gelatin” at “0.1” “%”. Medium should be changed once in “2” days.
Ideally, “EC” should express “PECAM1”, “ICAM1”, “CDH5”, “VWF”, “CD34”, “KDR” at the end of culture.
