Step 1: iPSC/ESC maintainance
day 0 ~ 1
culture “adherent” human PSC in “E8” for “1” days. For ECM, use “Synthemax” at “0.025” “g/l”. 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 |
| CHIR90021 | 1.0e-7 | mol/l |
Ideally, “PSC” should express “POU5F1” at the end of culture.
Step 2: Primitive streak 1
day 1 ~ 2
culture “adherent” human PSC in “RPMI” for “1” days. For ECM, use “Synthemax” at “0.025” “g/l”. 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 express “TBXT” at the end of culture.
Step 3: mesoderm 1
day 2 ~ 4
culture “adherent” human PSC in “RPMI” for “2” days. For ECM, use “Synthemax” at “0.025” “g/l”. Medium should be changed once in “2” days.
Step 4: mesoderm 2
day 4 ~ 6
culture “adherent” human PSC in “RPMI” for “2” days. For ECM, use “Synthemax” at “0.025” “g/l”. 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 |
