Step 1: mesoderm 1

day 0 ~ 4

culture “adherent” mouse ESC in “alpha-MEM” for “4” days. For ECM, use “Gelatin” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “4” days.

concentrationunit
FBS10%
2-mercaptoethanol0.0055mol/l

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

Step 2: endothelial 1

day 4 ~ 7

culture “adherent” mouse mesoderm in “alpha-MEM” for “3” days. For ECM, use “Gelatin” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “3” days.

concentrationunit
FBS10%
2-mercaptoethanol0.0055mol/l
VEGF5.0e-5g/l
cAMP5.0e-4mol/l

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