Abstract
Fetal Bovine Serum contains traces of ligands of the BMP pathway which affect the flow experiments with the ibidi perfusion system.
replacing EGM2 with 2% with EGM2 with 0.1% BSA 4h prior to onset of flow (with same media) allows cells to respond better and collectively to flow.
BSA 0.1% media prep
BSA 0.1% media prep
5m
5m
50 mL EGM2 without FBS
667 µL BSA 7.5% solution
filtrate through 0.22um yellow filter.
Add to slides 4h before starting flow.
Optional
Optional
adding BMP9/10 to flow experiment
in order to obtain a final 0.5 Mass Percent , add 1.4ul BMP9/10 of 10 Mass Percent initial concentration per perfusion unit (volume of 14ml)
add this to each perfusion unit during slide connection
