Step 1: iPSC/ESC maintainance

day 0 ~ 1

culture “adherent” human PSC in “mTeSR” for “1” days. For ECM, use “Matrigel” at “N/A” “N/A”. Medium should be changed once in “1” days.

Step 2: mesoderm 1

day 1 ~ 3

culture “adherent” human PSC in “DMEM/F12” for “2” 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 “2” days.

concentrationunit
BMP43.0e-5g/l
CHIR1.5e-6mol/l

Step 3: endothelial 1

day 3 ~ 5

culture “adherent” human PSC in “EGM2” for “2” 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 “2” days.

concentrationunit
VEGF5.0e-5g/l
SB4315421.0e-5mol/l

Ideally, “EC” should express “MECOM”, “KDR”, “CDH5”, “VWF”, “ERG”, “DLL4”, “EFNB2”, “NOS3”, “NR2F2” at the end of culture.
