Step 1: iPSC/ESC maintainance

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

culture “adherent” human PSC in “StemFlex Medium”. For ECM, use “Vitronectin” at “N/A” “N/A”.

Ideally, “PSC” should express “OCT3/4” at the end of culture.

Step 2: Primitive streak 1

day 1 ~ 2

culture “spheroid” human PSC in “StemPro” for “1” days. Medium should contain factors shown in the following table, and should be changed once in “1” days.

concentrationunit
Y276321.0e-5mol/l
BMP42.0e-6g/l

Step 3: Primitive streak 2

day 2 ~ 5

culture “spheroid” human PSC in “StemPro” for “3” days. Medium should contain factors shown in the following table, and should be changed once in “3” days.

concentrationunit
Activin A1.2e-6g/l
FGF5.0e-6g/l
BMP43.0e-5g/l

Step 4: mesoderm 1

day 5 ~ 9

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

concentrationunit
VEGF1.0e-5g/l
SB4315425.4e-6mol/l
Dorsomorphin5.0e-7mol/l
Y276321.0e-5mol/l

Ideally, “mesoderm” should express “MESP1”, “TBXT” at the end of culture.
