Step 1: iPSC/ESC maintainance

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

culture “adherent” human PSC in “E8”. For ECM, use “Matrigel” at “2.5” “%”. Medium should contain factors shown in the following table.

concentrationunit
Y276321.0e-5mol/l

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

Step 2: Primitive streak 1

day 1 ~ 2

culture “adherent” human PSC in “RPMI1640” for “1” days. For ECM, use “Matrigel” at “2.5” “%”. Medium should contain factors shown in the following table, and should be changed once in “1” days.

concentrationunit
B272%
GlutaMAX0.002mol/l
Ascorbic Acid0.06g/l
CHIR900216.0e-6mol/l

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

Step 3: mesoderm 1

day 2 ~ 3

culture “adherent” human PSC in “RPMI1640” for “1” days. For ECM, use “Matrigel” at “2.5” “%”. Medium should contain factors shown in the following table, and should be changed once in “1” days.

concentrationunit
B272%
GlutaMAX0.002mol/l
Ascorbic Acid0.06g/l
VEGF5.0e-5g/l
FGF1.0e-5g/l

Ideally, “HEP” should express “CDH5”, “CD34”, “PECAM1”, “KDR” at the end of culture.

Step 4: mesoderm 2

day 3 ~ 4 (duration missing in database; assumed 1 day)

culture “adherent” human PSC in “RPMI1640”. For ECM, use “Matrigel” at “2.5” “%”. Medium should contain factors shown in the following table.

concentrationunit
B272%
GlutaMAX0.002mol/l
Ascorbic Acid0.06g/l
VEGF5.0e-5g/l
FGF1.0e-5g/l
SB4315421.0e-5mol/l

Ideally, “HSPC” should express “CD34”, “CD43” at the end of culture.

Step 5: endothelial 1

day 4 ~ 6

culture “adherent” human HEP in “EGM” for “2” days. For ECM, use “Gelatin” at “0.1” “%”. Medium should be changed once in “2” days.

Ideally, “EC” should express “PECAM1”, “ICAM1”, “CDH5”, “VWF”, “CD34”, “KDR” at the end of culture.
