Step 1: iPSC/ESC maintainance

day 0 ~ 1

culture “adherent” human PSC in “MEF-CM” 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
FGF1.0e-5g/l
PSA——
knockout serum replacement——
NEAA——
GlutaMAX——
2-mercaptoethanol——

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

Step 2: Primitive streak 1

day 1 ~ 3

culture “adherent” human PSC in “APEL medium” 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.

concentrationunit
CHIR900218.0e-6mol/l
antibiotic-antimycotic0.5%

Ideally, “PS” should express “TBXT”, “MIXL1” at the end of culture.

Step 3: mesoderm 1

day 3 ~ 5

culture “adherent” human PSC in “APEL medium” 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.

concentrationunit
FGF92.0e-4g/l
Heparin0.001g/l
antibiotic-antimycotic0.5%

Ideally, “IM” should express “GATA3”, “HOXD11” at the end of culture.

Step 4: endothelial 1

day 5 ~ 7

culture “spheroid” human PSC in “APEL medium” for “2” days. Medium should contain factors shown in the following table, and should be changed once in “2” days.

concentrationunit
CHIR900215.0e-6mol/l
FGF92.0e-4g/l
antibiotic-antimycotic0.5%
Heparin0.001g/l

Ideally, “EC” should express “PECAM1”, “KDR”, “SOX17” at the end of culture.

Step 5: endothelial 2

day 7 ~ 9

culture “spheroid” human PSC in “APEL medium” for “2” days. Medium should contain factors shown in the following table, and should be changed once in “2” days.

concentrationunit
antibiotic-antimycotic0.5%
Heparin0.001g/l

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