Step 1: iPSC/ESC maintainance

day 0 ~ 1

culture “adherent” human PSC in “mTeSR Plus” for “1” days. For ECM, use “Geltrex” at “1” “%”. Medium should contain factors shown in the following table, and should be changed once in “1” days.

concentrationunit
PSA1%
Thiazovivin1.0e-6mol/l

Ideally, “PSC” should be obtained at the end of culture.

Step 2: Primitive streak 1

day 1 ~ 2

culture “adherent” human PSC in “IMDM” for “1” days. For ECM, use “Geltrex” at “1” “%”. Medium should contain factors shown in the following table, and should be changed once in “1” days.

Ideally, “PS” should be obtained at the end of culture.

Step 3: Primitive streak 2

day 2 ~ 3 (duration missing in database; assumed 1 day)

culture “adherent” human PSC in “unspecified medium”. For ECM, use “Geltrex” at “1” “%”.

Step 4: mesoderm 1

day 3 ~ 4

culture “adherent” human PSC in “IMDM” for “1” days. For ECM, use “Geltrex” at “1” “%”. Medium should contain factors shown in the following table, and should be changed once in “1” days.

Ideally, “mesoderm” should be obtained at the end of culture.

Step 5: mesoderm 2

day 4 ~ 5 (duration missing in database; assumed 1 day)

culture “adherent” human PSC in “unspecified medium”. For ECM, use “Geltrex” at “1” “%”.

Step 6: endothelial 1

day 5 ~ 6

culture “adherent” human PSC in “IMDM” for “1” days. For ECM, use “Geltrex” at “1” “%”. Medium should contain factors shown in the following table, and should be changed once in “1” days.

Ideally, “EC” should express “CDH5”, “PECAM1”, “SOX17”, “CXCR4”, “DLL4” at the end of culture.

Step 7: endothelial 2

day 6 ~ 7

culture “adherent” human PSC in “IMDM” for “1” days. For ECM, use “Geltrex” at “1” “%”. Medium should contain factors shown in the following table, and should be changed once in “1” days.
