Step 1: iPSC/ESC maintainance

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

culture “adherent” human PSC in “E8”. For ECM, use “Matrigel” at “N/A” “N/A”. Medium should contain factors shown in the following table.

concentrationunit
Y276321.0e-5mol/l

Step 2: Primitive streak 1

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

culture “adherent” human PSC in “Vascular SFM”. For ECM, use “Matrigel” at “N/A” “N/A”. Medium should contain factors shown in the following table.

concentrationunit
CHIR90021——
BMP4——
Heparin——
B27——
EGF——
FGF——
Ascorbic Acid——

Step 3: mesoderm 1

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

culture “adherent” human PSC in “Vascular SFM”. For ECM, use “Matrigel” at “N/A” “N/A”. Medium should contain factors shown in the following table.

concentrationunit
Heparin——
B27——
EGF——
FGF——
Ascorbic Acid——

Step 4: endothelial 1

day 3 ~ 4 (duration missing in database; assumed 1 day)

culture “adherent” human PSC in “Vascular SFM”. For ECM, use “FN1” at “0.01” “g/l”. Medium should contain factors shown in the following table.

concentrationunit
VEGF——
forskolin——
Heparin——
B27——
EGF——
FGF——
Ascorbic Acid——

Ideally, “EC” should express “PECAM1”, “CDH5”, “VWF”, “ETV2”, “NRP1” at the end of culture.

Step 5: endothelial 2

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

culture “adherent” human PSC in “Vascular SFM”. For ECM, use “FN1” at “0.01” “g/l”. Medium should contain factors shown in the following table.

concentrationunit
S1P——
VEGF——
Heparin——
B27——
EGF——
FGF——
Ascorbic Acid——

Ideally, “EC” should express “PECAM1”, “CDH5”, “VWF”, “ETV2”, “NRP1” at the end of culture.
