Step 1: iPSC/ESC maintainance

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

culture “adherent” human PSC and human PSC and human PSC in “Nutristem medium”. “PSC” should be “downregulated” for “YAP1”. “PSC” should be “upregulated” for “YAP1”. For ECM, use “Matrigel” at “N/A” “N/A”.

Ideally, “PSC” should express “POU5F1”, “NANOG”, “SOX2” at the end of culture.

Step 2: Primitive streak 1

day 1 ~ 2

culture “spheroid” human PSC and human PSC and human PSC in “StemPro-34 medium” for “1” days. “PSC” should be “downregulated” for “YAP1”. “PSC” should be “upregulated” for “YAP1”. Medium should contain factors shown in the following table, and should be changed once in “1” days.

Transferrin0.15g/l
Ascorbic Acid0.05g/l

BMP41.0e-5g/l

Step 3: Primitive streak 2

day 2 ~ 4

culture “spheroid” human PSC and human PSC and human PSC in “StemPro-34 medium” for “2” days. “PSC” should be “downregulated” for “YAP1”. “PSC” should be “upregulated” for “YAP1”. Medium should contain factors shown in the following table, and should be changed once in “2” days.

Step 4: endothelial 1

day 4 ~ 7

culture “adherent” human PSC and human PSC and human PSC in “StemPro-34 medium” for “3” days. “PSC” should be “downregulated” for “YAP1”. “PSC” should be “upregulated” for “YAP1”. For ECM, use “Matrigel” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “3” days.

FLT3L1.0e-5g/l

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

Step 5: endothelial 2

day 7 ~ 14

culture “adherent” human PSC and human PSC and human PSC in “StemPro-34 medium” for “7” days. “PSC” should be “downregulated” for “YAP1”. “PSC” should be “upregulated” for “YAP1”. For ECM, use “Matrigel” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “7” days.
