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 “N/A” “N/A”. Medium should contain factors shown in the following table.

concentrationunit
Dispase1000U/l
Y276325.0e-6mol/l

Step 2: mesoderm 1

day 1 ~ 2

culture “adherent” human PSC in “IMDM” 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.

concentrationunit
F1224%
N20.5%
B271%
BSA-lipid rich0.05%
CHIR900215.0e-6mol/l
BMP42.0e-5g/l

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

Step 3: mesoderm 2

day 2 ~ 3

culture “adherent” human PSC in “IMDM” 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.

concentrationunit
F1224%
N20.5%
B271%
BSA-lipid rich0.05%
FGF5.0e-5g/l
Activin A5.0e-5g/l
BMP42.0e-5g/l

Step 4: endothelial 1

day 3 ~ 4

culture “adherent” human mesoderm in “IMDM” 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.

concentrationunit
F1224%
N20.5%
B271%
BSA-lipid rich0.05%
VEGF5.0e-5g/l
SB4315421.0e-5mol/l
BMP42.0e-5g/l

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

Step 5: endothelial 2

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

culture “adherent” human EC in “EGM2-MV”. For ECM, use “Gelatin” at “0.2” “%”. Medium should contain factors shown in the following table.

concentrationunit
FBS15%

Ideally, “EC” should express “CDH5”, “PECAM1”, “KDR” at the end of culture.
