Step 1: iPSC/ESC maintainance
day 0 ~ 1
culture “adherent” unknown species cell and mouse PSC in “DMEM” for “1” days. For ECM, use “MEF feeder” at “N/A” “N/A”. Medium should contain factors shown in the following table, and should be changed once in “1” days.
| concentration | unit | |
|---|---|---|
| LIF | 1.0e+6 | U/l |
| FBS | 20 | % |
| PSA | 100000 | U/l |
| streptomycin | 0.1 | g/l |
| NEAA | 1 | % |
| 2-mercaptoethanol | 1.0e-4 | mol/l |
Ideally, “PSC” should express “alkaline phosphatase”, “HO-1”, “proteoglycan-4”, “angiotensinogen”, “Oct3/4A”, “NANOG” at the end of culture.
Step 2: mesoderm 1
day 1 ~ 2 (duration missing in database; assumed 1 day)
culture “adherent” unknown species cell and mouse PSC in “unspecified medium”.
Ideally, “mesoderm” should be obtained at the end of culture.
Step 3: endothelial 1
day 2 ~ 6
culture “adherent” unknown species cell and mouse PSC in “alpha-MEM” for “4” days. For ECM, use “Collagen” at “0.05” “g/m2”. Medium should contain factors shown in the following table, and should be changed once in “4” days.
| concentration | unit | |
|---|---|---|
| FBS | 10 | % |
| PSA | 100000 | U/l |
| streptomycin | 0.1 | g/l |
| NEAA | 1 | % |
| 2-mercaptoethanol | 1.0e-4 | mol/l |
Step 4: endothelial 2
day 6 ~ 36
culture “adherent” unknown species cell and mouse PSC in “alpha-MEM” for “30” days. For ECM, use “FN1” at “0.02” “g/l”. Medium should contain factors shown in the following table, and should be changed once in “30” days.
| concentration | unit | |
|---|---|---|
| FBS | 10 | % |
| PSA | 100000 | U/l |
| streptomycin | 0.1 | g/l |
| NEAA | 1 | % |
| 2-mercaptoethanol | 1.0e-4 | mol/l |
| VEGF | 5.0e-5 | g/l |
Ideally, “EC” should express “VWF”, “NOS3”, “Flt-1”, “CD34”, “Tie-2” at the end of culture.
