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 contain factors shown in the following table, and should be changed once in “1” days.

concentrationunit
CHIR900211.0e-6mol/l
PSA0.001g/l
Y276321.0e-5mol/l

Step 2: Primitive streak 1

day 1 ~ 2

culture “adherent” human PSC in “RPMI” 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
Activin A1.0e-4g/l
B27 (-Insulin)——
Matrigel——

Step 3: Primitive streak 2

day 2 ~ 3

culture “adherent” human PSC in “RPMI” 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
BMP45.0e-6g/l
CHIR900211.0e-6mol/l
B27 (-Insulin)——

Step 4: endothelial 1

day 3 ~ 6

culture “adherent” human PSC in “StemPro” for “3” 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 “3” days.

concentrationunit
VEGF3.0e-4g/l
BMP41.0e-5g/l
FGF5.0e-6g/l
Ascorbic Acid0.05g/l
MTG4.0e-4mol/l
Glutamine0.002mol/l

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

Step 5: endothelial 2

day 6 ~ 11

culture “adherent” unknown species cell in “EGM” for “5” days. For ECM, use “Gelatin” at “0.1” “%”. Medium should contain factors shown in the following table, and should be changed once in “5” days.

concentrationunit
VEGF2.0e-5g/l
FGF2.0e-5g/l
CHIR900211.0e-6mol/l

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