Step 1: iPSC/ESC maintainance

day 0 ~ 2

culture “adherent” mouse ESC in “DMEM” for “2” days. Medium should contain factors shown in the following table, and should be changed once in “2” days.

concentrationunit
FBS15%
NEAA1.0e-4mol/l
glutamine0.002mol/l
PSA0.05g/l
streptomycin0.075g/l
MTG8.6e-4%
LIF1.0e+6U/l

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

Step 2: mesoderm 1

day 2 ~ 4

culture “spheroid” mouse ESC in “IMDM” for “2” days. Medium should contain factors shown in the following table, and should be changed once in “2” days.

concentrationunit
FBS15%
glutamine0.002mol/l
PSA0.05g/l
streptomycin0.075g/l
MTG4.5e-4mol/l
Transferrin0.2g/l
Ascorbic Acid0.05g/l

Ideally, “ME” should express “CDH5”, “PECAM1”, “TEK”, “Scl”, “CD41”, “KDR”, “Cxcr4” at the end of culture.

Step 3: mesoderm 2

day 4 ~ 5 (duration missing in database; assumed 1 day)

culture “adherent” mouse ME in “IMDM”. “ME” should be “upregulated” for “HoxB4”. Medium should contain factors shown in the following table.

PSA0.05g/l
