Step 1: iPSC/ESC maintainance

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

culture “adherent” human PSC in “mTeSR”. “PSC” should be “unspecified regulation” for “ACVR1”. For ECM, use “Matrigel” at “0.15” “g/l”. 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: mesoderm 1

day 1 ~ 5

culture “spheroid” human PSC in “StemPro” for “4” days. “PSC” should be “unspecified regulation” for “ACVR1”. Medium should contain factors shown in the following table, and should be changed once in “4” days.

concentrationunit
glutamine0.002mol/l
Transferrin150g/l
Ascorbic Acid0.001mol/l
MTG4.0e-7mol/l
FGF5.0e-6g/l
Activin A3.6e-6g/l
BMP41.2e-5g/l

Step 3: mesoderm 2

day 5 ~ 7

culture “adherent” human PSC in “StemPro” for “2” days. “PSC” should be “unspecified regulation” for “ACVR1”. For ECM, use “Collagen” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “2” days.

concentrationunit
VEGF——
FGF——

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

Step 4: endothelial 1

day 7 ~ 10

culture “adherent” human EC in “Endothelial Cell Medium” for “3” days. “EC” should be “unspecified regulation” for “ACVR1”. For ECM, use “FN1” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “3” days.

concentrationunit
follistatin0.001g/l

Ideally, “EC” should express “PECAM1”, “CDH5”, “KDR”, “VWF”, “TEK”, “CD34” at the end of culture.
