Step 1: iPSC/ESC maintainance

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

culture “adherent” human PSC in “DMEM/F12”. For ECM, use “Fibroblast” at “N/A” “N/A”. Medium should contain factors shown in the following table.

concentrationunit
KSR20%
NEAA——
Glutamine0.002mol/l
2-mercaptoethanol1.0e-4mol/l
FGF2.0e-5g/l
PSA1%

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

Step 2: mesoderm 1

day 1 ~ 3

culture “adherent” human PSC and unknown species cell in “alpha-MEM” for “2” days. For ECM, use “type IV collagen” at “0.005” “g/l”. Medium should contain factors shown in the following table, and should be changed once in “2” days.

concentrationunit
FBS10%
FGF1.0e-5g/l
2-mercaptoethanol5.0e-5mol/l
PSA1%
Activin A6.0e-6g/l
BMP41.0e-5g/l

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

Step 3: endothelial 1

day 3 ~ 8

culture “adherent” human PSC and unknown species cell in “alpha-MEM” for “5” days. For ECM, use “type IV collagen” at “0.005” “g/l”. Medium should contain factors shown in the following table, and should be changed once in “5” days.
