ANN ARBOR — A tiny, transparent fish embryo and a string of surprises led scientists to a deeper understanding of the perplexing link between low calcium and colon cancer.
By studying zebrafish embryo skin, University of Michigan researchers decoded cell messages underlying abnormal colonic cell growth of the kind that can lead to tumors and colon cancer in calcium deficient individuals. They have also tested this new mechanism in human colon cancer cells. (more…)
In “before” and “after” photos from advertisements for wound-healing ointments, bandages and antibiotic creams, we see an injury transformed from an inflamed red gash to smooth and flawless skin.
What we don’t appreciate is the vital role that our own natural biomolecules play in the healing process, including their contribution to the growth of new cells and the development of new blood vessels that provide nutrients to those cells. (more…)
AUSTIN, Texas — University of Texas at Austin researchers have demonstrated a new and more effective method for regrowing blood vessels in the heart and limbs — a research advancement that could have major implications for how we treat heart disease, the leading cause of death in the Western world.
The treatment method developed by Cockrell School of Engineering Assistant Professor Aaron Baker could allow doctors to bypass surgery and instead repair damaged blood vessels simply by injecting a lipid-incased substance into a patient. Once inside the body, the substance stimulates cell growth and spurs the growth of new blood vessels from pre-existing ones. (more…)
Small bypass vessels which act as a ‘back-up system’ for the heart’s main arteries play a significant role in reducing the mortality of patients with coronary artery disease, according to new research. (more…)
