Step 1: iPSC/ESC maintainance
day 0 ~ 1 (duration missing in database; assumed 1 day)
culture “adherent” human PSC in “E8”. For ECM, use “Matrigel” at “N/A” “N/A”. Medium should contain factors shown in the following table.
| concentration | unit | |
|---|---|---|
| TGF-b | — | — |
| FGF | — | — |
| Y27632 | 1.0e-5 | mol/l |
| KSR | 15 | % |
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 “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 | |
|---|---|---|
| BMP4 | 4.0e-5 | g/l |
| Activin A | 4.0e-5 | g/l |
Ideally, “PS” should be obtained at the end of culture.
Step 3: endothelial 1
day 2 ~ 8
culture “unspecified method” human PSC in “unspecified medium” for “6” days. Medium should be changed once in “6” days.
Ideally, “EC” should be obtained at the end of culture.
