Step 1: iPSC/ESC maintainance
day 0 ~ 3
culture “adherent” human PSC in “mTeSR” for “3” days. For ECM, use “Matrigel” at “N/A” “N/A”. Medium should be changed once in “3” days.
Step 2: endothelial 1
day 3 ~ 9
culture “adherent” human PSC in “DMEM/F12” for “6” 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 “6” days.
| concentration | unit | |
|---|---|---|
| KSR | — | — |
| NEAA | — | — |
| GlutaMAX | — | — |
| 2-mercaptoethanol | — | — |
Ideally, “EC” should be obtained at the end of culture. Ideally, “NPC” should be obtained at the end of culture.
Step 3: endothelial 2
day 9 ~ 11
culture “adherent” human PSC in “endothelial cell medium” 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 | |
|---|---|---|
| retinoic acid | — | — |
Ideally, “EC” should express “CDH5”, “PECAM1”, “GLUT-1”, “P-gp”, “VEGF”, “Wnt7a”, “ZO-1”, “Claudin-5”, “HIF1A” at the end of culture.
