Step 1: iPSC/ESC maintainance
day 0 ~ 1 (duration missing in database; assumed 1 day)
culture “adherent” human PSC in “mTeSR”. For ECM, use “Matrigel” at “N/A” “N/A”.
Ideally, “PSC” should express “AP”, “TRA-1-80”, “NANOG”, “TRA-1-60”, “POU5F1” at the end of culture.
Step 2: Primitive streak 1
day 1 ~ 3
culture “adherent” human PSC in “DMEM/F12” 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 | |
|---|---|---|
| CHIR90021 | 0.006 | mol/l |
| GlutaMax | 0.0025 | mol/l |
| Ascorbic Acid | 0.06 | g/l |
Step 3: endothelial 1
day 3 ~ 6
culture “adherent” human PSC in “DMEM/F12” for “3” 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 “3” days.
| concentration | unit | |
|---|---|---|
| Ascorbic Acid | 0.06 | g/l |
Ideally, “HE” should express “CD34”, “PECAM1” at the end of culture.
Step 4: endothelial 2
day 6 ~ 7 (duration missing in database; assumed 1 day)
culture “adherent” human PSC in “Vasculife medium”.
Ideally, “EC” should express “VWF”, “PECAM1”, “CDH5”, “CDH5” at the end of culture.
