MRI based on a sugar molecule can tell cancerous from noncancerous cells
The MRI technique, so far tested only in test tube-grown cells and mice, is described in a report published March 27 in the online journal Nature Communications. …

Key link responsible for colon cancer initiation, metastasis
Now, an ASU research team led by Biodesign Institute executive director Dr. Ray DuBois, M.D., PhD, has shown that a key genetic culprit, called CXCR2, is implicated in the tumor formation, growth and progression in a mouse model of colon cancer. …
Shining stem cells reveals how our skin is maintained
The results have just been published in the journal Cell Stem Cell. New knowledge challenge stem cell models The skin consists of many different cell types, including hair cells, fat- and sweat glands. …
Self-perpetuating signals may drive tumor cells to spread
Many different types of cells in our body can crawl and migrate to distinct locations, sometimes over long distances. Immune system cells, for example, move to a wound site to kill microorganisms during an infection, and connective tissue cells (fibroblasts) move there to repair damaged areas. …
New insights on cancer cell signaling
Wnt proteins are a large family of proteins that active signaling pathways (a set of biological reactions in a cell) to control several vital steps in embryonic development. In adults, Wnt-mediated functions are frequently altered in many types of cancers and, specifically, within cell subpopulations that possess stem cell-like properties…
Water governs cell movement: Aquaporins play key role, new research finds
The ability of cells to move and change shape is significant in many biological processes. White blood corpuscles gather at "hotspots" like infections and inflammations. Stem cells in the embryo move off in different directions to make the organs of the body. One unwanted movement is the movement of tumour cells, which lead to cancer metastasis…
