Step 1: iPSC/ESC maintainance

day 0 ~ 1

culture “adherent” human PSC in “E8” for “1” days. For ECM, use “Vitronectin” at “N/A” “N/A”. Medium should be changed once in “1” days.

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

Step 2: mesoderm 1

day 1 ~ 6

culture “adherent” human PSC in “unspecified medium” for “5” days. For ECM, use “Vitronectin” at “N/A” “N/A”. Medium should be changed once in “5” days.

Step 3: endothelial 1

day 6 ~ 8

culture “adherent” unknown species cell in “unspecified medium” for “2” days. For ECM, use “Vitronectin” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “2” days.

concentrationunit
retinoic acid1.0e-5mol/l
FGF2.0e-6g/l

Ideally, “EC” should express “CLDN5”, “OCLN”, “ABCB1”, “SLC2A1” at the end of culture.

Step 4: endothelial 2

day 8 ~ 10

culture “adherent” unknown species cell in “unspecified medium” for “2” days. For ECM, use “Collagen IV and Fibronectin” at “N/A” “N/A”. Medium should be changed once in “2” days.

Ideally, “EC” should express “CLDN5”, “OCLN”, “ABCB1”, “SLC2A1” at the end of culture.
