Step 1: iPSC/ESC maintainance

day 0 ~ 1 (duration missing in database; assumed 1 day)

culture “adherent” human PSC in “mTeSR”. For ECM, use “Matrigel” at “3” “%”. Medium should contain factors shown in the following table.

concentrationunit
Y276321.0e-5mol/l

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

Step 2: Primitive streak 1

day 1 ~ 3

culture “adherent” human PSC in “RPMI” for “2” days. For ECM, use “Matrigel” at “3” “%”. Medium should contain factors shown in the following table, and should be changed once in “2” days.

concentrationunit
CHIR900211.2e-5mol/l

Step 3: mesoderm 1

day 3 ~ 5

culture “adherent” human PSC in “RPMI” for “2” days. For ECM, use “Matrigel” at “3” “%”. Medium should contain factors shown in the following table, and should be changed once in “2” days.

concentrationunit
B27——

Step 4: endothelial 1

day 5 ~ 11

culture “device” human PSC in “RPMI 1640” for “6” days. For ECM, use “Matrigel” at “1.5” “%”. Medium should contain factors shown in the following table, and should be changed once in “6” days.

concentrationunit
VEGF1.0e-4g/l
Glutamine1%
B27——

Ideally, “EC” should express “PECAM1” at the end of culture.
