Step 1: iPSC/ESC maintainance

day 0 ~ 1

culture “adherent” human PSC in “mTeSR Plus” for “1” days. “PSC” should be “upregulated” for “NKX3.1”. For ECM, use “Matrigel” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “1” days.

concentrationunit
Y276325.0e-6mol/l

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

Step 2: mesoderm 1

day 1 ~ 2

culture “adherent” human PSC in “Advanced DMEM/F-12” for “1” days. “PSC” should be “upregulated” for “NKX3.1”. For ECM, use “Matrigel” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “1” days.

concentrationunit
CHIR900216.0e-6mol/l
GlutaMAX1x
Ascorbic Acid0.06g/l

Ideally, “mesoderm” should express “TBXT”, “TBX6”, “MSGN1”, “MIXL1” at the end of culture.

Step 3: mesoderm 2

day 2 ~ 3

culture “adherent” human mesoderm in “Advanced DMEM/F-12” for “1” days. “mesoderm” should be “upregulated” for “NKX3.1”. For ECM, use “Matrigel” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “1” days.

concentrationunit
Dox0.005g/l
modRNA——
GlutaMAX1x
Ascorbic Acid0.06g/l

Ideally, “iMPC” should express “NKX3.1”, “CSPG4”, “PDGFRB”, “DES” at the end of culture.

Step 4: endothelial 1

day 3 ~ 10

culture “adherent” human iMPC and human EC and human MSC in “EGM2” for “7” days. For ECM, use “Gelatin” at “1” “%”. Medium should be changed once in “7” days.

Ideally, “Pericyte/SMC” should express “PDGFRB”, “NT5E”, “CSPG4” at the end of culture. Ideally, “Pericyte/SMC” should express “ACTA2”, “CNN1”, “TAGLN”, “MYOCD”, “TPM1”, “MYH11”, “FN1”, “COL1A1”, “COL1A2” at the end of culture.
