Step 1: iPSC/ESC maintainance

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

culture “adherent” human ESC in “DMEM/F12”. Medium should contain factors shown in the following table.

concentrationunit
KSR15%
NEAA1%
PSA0.5%
GlutaMAX0.002mol/l
2-mercaptoethanol1.0e-4mol/l
FGF4.0e-6g/l

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

Step 2: mesoderm 1

day 1 ~ 3

culture “adherent” human ESC in “RPMI” for “2” 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 “2” days.

concentrationunit
FBS15%
GlutaMAX0.002mol/l
2-mercaptoethanol1.0e-4mol/l
NEAA1%
PSA1%

Step 3: endothelial 1

day 3 ~ 5

culture “adherent” human ESC in “EBM-2” for “2” 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 “2” days.
