Step 1: iPSC/ESC maintainance

day 0 ~ 2

culture “adherent” human PSC in “mTeSR” for “2” days. For ECM, use “Matrigel” at “N/A” “N/A”. Medium should be changed once in “2” days.

Ideally, “PSC” should express “POU5F1”, “TRA1-60” at the end of culture.

Step 2: Primitive streak 1

day 2 ~ 8

culture “adherent” human PSC in “DMEM/F12” for “6” 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 “6” days.

Step 3: endothelial 1

day 8 ~ 10

culture “adherent” human PSC in “Human Endothelial-SFM” 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
PDS1%
FGF2.0e-5g/l
retinoic acid2.0e-5mol/l
Hydrocortisone1.3e-6mol/l

Ideally, “EC” should express “VWF”, “Ulex”, “TJP1”, “CLDN5”, “OCLN”, “IGF1R”, “SLC3A2”, “SLC2A1”, “LRP1”, “TfR”, “ABCB1”, “ABCC1”, “ABCG2” at the end of culture.

Step 4: endothelial 2

day 10 ~ 13

culture “adherent” human EC in “Human Endothelial-SFM” for “3” days. For ECM, use “collagen IV, fibronectin” at “0.4” “g/l”. Medium should contain factors shown in the following table, and should be changed once in “3” days.
