Starving tumors of blood vessels may not be the way to go

Dense networks of blood vessels thought to spur cancer’s growth could actually hinder rather than promote tumor progression, according to a new study at the University of California, San Diego.

The findings partly explain why drugs designed to treat cancer by strangling its blood supply have been disappointing when used alone and why those treatments are more effective when combined with traditional chemotherapy

Using a whole-genome approach, researchers have found more than one hundred human protein compounds that can slow blood vessel growth. This could lead to treatments against diseases that depend on the growth of new blood vessels, including cancer, macular degeneration and rheumatoid arthritis.

A tissue engineering group has succeeded in creating functional blood vessels and cardiac tissue, using a printer that dispenses cells instead of ink. The work, published this month in Tissue Engineering, is among the first to produce functional three-dimensional tissue using a printer, and a milestone on the way to the goal of printing out whole organs.

A recent study in Journal of Neuroimaging suggests that cognitively normal adults exhibiting atrophy of their temporal lobe or damage to blood vessels in the brain are more likely to develop Alzheimer's disease. Older adults showing signs of both conditions were seven-times more likely to develop Alzheimer's than their peers.

Blood vessels that have been tissue-engineered from bone marrow adult stem cells may in the future serve as a patient's own source of new blood vessels following a coronary bypass or other procedures that require vessel replacement, according to new research from the University at Buffalo Department of Chemical and Biological Engineering.
