Step 1: iPSC/ESC maintainance
day 0 ~ 1
culture “adherent” human PSC in “E8” 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 be obtained at the end of culture.
Step 2: Primitive streak 1
day 1 ~ 2
culture “adherent” human PSC in “RPMI” for “1” days. Medium should contain factors shown in the following table, and should be changed once in “1” days.
| concentration | unit | |
|---|---|---|
| CHIR90021 | 6.0e-6 | mol/l |
Ideally, “PS” should be obtained at the end of culture.
Step 3: mesoderm 1
day 2 ~ 4
culture “adherent” human PS in “RPMI” for “2” days. Medium should contain factors shown in the following table, and should be changed once in “2” days.
| concentration | unit | |
|---|---|---|
| IWP2 | 2.5e-6 | mol/l |
Ideally, “mesoderm” should be obtained at the end of culture.
