The enzyme solution with tissue is taken out and put in the stomacher strainer bags with inner tissue filter at the rate of 25 ml of enzyme solution per bag. The air in the bag is removed to prevent the bag from rupturing and the bag is sealed at least twice at the top using a heat sealer. The bag is placed in the stomacher 400 Circulator and the stomacher is run at 150 rpm for 10 minutes at 37˚C.
The Stomacher® 80 was used to blend solid tumors for 12 minutes.
Notch receptor signaling pathways play an important role not only in normal breast development but also in breast cancer development and progression. We assessed the role of Notch receptors in stem cell activity in breast cancer cell lines and nine primary human tumor samples. Our findings suggest that Notch4-targeted therapies will be more effective than targeting Notch1 in suppressing breast cancer recurrence, as it is initiated by breast cancer stem cells.
