Calcofluor-white Calcofluor-white Calcofluor-white is a special fluorescent stain that binds strongly to structures containing cellulose and chitin. In plant cell biology research, it is used for the staining of cell walls of both algae and higher plants. It is also useful in medicine and animal biology for the identification of fungi in the tissue, (it binds to the chitin in the cell walls of the fungi). In research, calcofluor-white is also used to stain bud scars of yeast cells because the bud scars have a higher content of chitin, which stains them more than the rest of the cell membrane. Due
Stromal cell-derived factor 1 receptors, of which CXCR stands out, regulate multiple processes such as morphogenesis, angiogenesis, and immune responses and are considered potential targets for drug development. In the gastrointestinal tract system, the CXCL12-CXCR4 axis is under investigation as an anti-fibrotic therapy in the treatment for chronic pancreatitis. For instance, blocking CXCR4, the receptor for CXCL12, with Plerixafor (AMD-3100) increased the effectiveness of combretastatin in a mouse model of breast cancer, presumably by preventing macrophages from being recruited to tumours.[15][16] Stromal cell-derived factor 1 The stromal cell-derived factor 1 (SDF1), also known as C-X-C motif chemokine 12 (CXCL12), is a chemokine protein that
