AURORA, Colo. (Sept. 2, 2014) A team of scientists from the University of Colorado School of Medicine has reported the breakthrough discovery of a process to expand production of stem cells used to treat cancer patients. These findings could have implications that extend beyond cancer, including treatments for inborn immunodeficiency and metabolic conditions and autoimmune diseases.

In an article published Aug. 29 in PLOS ONE, researchers from the Charles C. Gates Center for Regenerative Medicine and Stem Cell Biology and Taiga Biotechnologies, Inc. said they have uncovered the keys to the molecular code that appear to regulate the ability of blood stem cells to reproduce and retain their stem-like characteristics.

The team developed protein products that can be directly administered to blood stem cells to encourage them to multiply without permanent genetic modifications.

"Use of stem cells to treat cancer patients who face bone marrow transplants has been a common practice for four decades," said Yosef Refaeli, Ph.D., an associate dermatology professor and one of the study's lead scientists. "The biggest challenge, however, has been finding adequate supplies of stem cells that help patients fight infection after the procedure."

Gates Stem Cell Center Director Dennis Roop, Ph.D., recognized the magnitude of the team's work.

"Researchers have long attempted to increase the number of blood stem cells in a lab," Roop said. "Most of those approaches have been limited by the nature of the resulting cells or the inadequate number of cells produced."

The technology described in the PLOS ONE article has worked with blood stem cells obtained from cord blood, adult bone marrow or peripheral blood from adults.
