Step 1: iPSC/ESC maintainance
day 0 ~ 1
culture “adherent” human PSC in “mTeSR” for “1” 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 “1” days.
| concentration | unit | |
|---|---|---|
| Y27632 | 5.0e-6 | mol/l |
Ideally, “PSC” should express “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 | 6.0e-6 | mol/l |
| Ascorbic Acid | 0.06 | g/l |
| GlutaMAX | 0.0025 | mol/l |
Ideally, “PS” should express “brachyury” at the end of culture.
Step 3: endothelial 1
day 3 ~ 6
culture “adherent” human PS 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 |
| GlutaMAX | 0.0025 | mol/l |
Ideally, “EPC” should express “CD34”, “PECAM1”, “CDH5”, “CD117”, “KDR”, “TIE-2” at the end of culture.
Step 4: endothelial 2
day 6 ~ 7 (duration missing in database; assumed 1 day)
culture “adherent” human EPC in “EGM2”. For ECM, use “Collagen” at “N/A” “N/A”.
Ideally, “EC” should express “PECAM1”, “CDH5”, “VWF”, “ICAM1”, “KDR” at the end of culture.
