Stained tissues were counted in five microscopic fields. The analysis was performed in Imaris 7.6 (Bitplane). Phospho-Rac1 stain was predominantly cytosol. Phospho-Rac1 scores (0–300) were calculated by multiplying the staining intensity (0, 1, 2, or 3) by the staining extent (0%– 100%).
For immunofluorescence, antibodies used were anti-Rac1 (BD 610650, BD Transduction Laboratories™), anti-CD44 (#5640, Cell Signaling), anti-Sox2 (#3579, Cell Signaling), anti-Oct-4 (#83932, Cell Signaling), anti-Nanog (#8822, Cell Signaling), anti-c-Myc (sc-40, Santa Cruz Biotechnology), anti-N-cadherin (BD 610920, BD Transduction Laboratories™), and anti-Slug (#9585, Cell Signaling).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
