Tracking T Cell Division with CFSE and Flow Cytometry

Tracking T cell division with CFSE and flow cytometry shows how immune cells respond after stimulation. The cell cycle is a normal process of life. During it, a cell changes step by step and divides into two daughter cells. This happens throughout life when the body needs new cells for growth and repair.

For most immunology studies, measuring proliferation of immune cells is a key step and the CFSE fluorescent dye-based method is commonly used. Proper cell division is important for immune cells since it regulates both levels and specificity of an immune response. For example, T-cells proliferate to identify and kill cancer cells and B-cells unde...
