Step 1: iPSC/ESC maintainance
day 0 ~ 1
culture “adherent” human PSC in “E8” for “1” days. For ECM, use “Vitronectin” at “N/A” “N/A”. Medium should be changed once in “1” days.
Ideally, “PSC” should be obtained at the end of culture.
Step 2: Primitive streak 1
day 1 ~ 2
culture “adherent” human PSC in “E6 medium” for “1” days. For ECM, use “Vitronectin” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “1” days.
| concentration | unit | |
|---|---|---|
| CHIR | 6.0e-6 | mol/l |
Step 3: mesoderm 1
day 2 ~ 3 (duration missing in database; assumed 1 day)
culture “unspecified method” human PSC in “alpha MEM”.
Step 4: endothelial 1
day 3 ~ 5
culture “adherent” human PSC in “ECGM” for “2” days. For ECM, use “COL1A1” at “N/A” “N/A”. 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 |
| VEGF | 1.0e-5 | g/l |
| SB431542 | 1.0e-5 | mol/l |
| Y27632 | 1.0e-5 | mol/l |
Ideally, “EC” should express “KDR”, “HK1”, “HK2”, “PFKFB3”, “VEGF” at the end of culture.
