Step 1: iPSC/ESC maintainance
day 0 ~ 1
culture “spheroid” human PSC in “E8” for “1” days. For ECM, use “PNIPAAm-PEG hydrogel” at “10” “%”. Medium should contain factors shown in the following table, and should be changed once in “1” days.
| concentration | unit | |
|---|---|---|
| Y27632 | 1.0e-5 | mol/l |
Ideally, “PSC” should express “OCT3/4”, “NANOG” at the end of culture.
Step 2: endothelial 1
day 1 ~ 4
culture “spheroid” human PSC in “N2B27 medium” for “3” days. For ECM, use “PNIPAAm-PEG hydrogel” at “10” “%”. Medium should contain factors shown in the following table, and should be changed once in “3” days.
| concentration | unit | |
|---|---|---|
| N2 | — | — |
| B27 | — | — |
| CHIR90021 | 8.0e-6 | mol/l |
| BMP | 2.5e-5 | g/l |
Step 3: endothelial 2
day 4 ~ 5
culture “spheroid” human PSC in “StemPro-34 SFM medium” for “1” days. For ECM, use “PNIPAAm-PEG hydrogel” at “10” “%”. Medium should contain factors shown in the following table, and should be changed once in “1” days.
| concentration | unit | |
|---|---|---|
| VEGF | 2.0e-4 | g/l |
| Forskolin | 2.0e-6 | mol/l |
Ideally, “EC” should express “PECAM1”, “CDH5” at the end of culture.
