December 12, 2008 - A recent study by LSI faculty member Sean Morrison shows that previous estimates from conventional melanoma models severely underestimate the tumor causing potential of melanoma cells.
October 17, 2008 - LSI faculty member Sean Morrison and colleagues have shown in a recent study that identified four genes previously implicated in the control of cancer also play key roles in the aging process and stem-cell regulation. These four genes were found to switch stem cells on and off in a coordinated fashion as cells age to reduce cancer risk and also function to shut down stem-cell function in aging tissues, limiting regeneration.
February 4, 2008 - Two teams of University of Michigan researchers have tracked down the cells responsible for neurofibromatosis type 1, a disfiguring, incurable condition and one of the most common hereditary disorders.
November 21, 2007 - LSI faculty and director of the Center for Stem Cell Biology is interviewed on News/Talk 760 WJR about stem cell discoveries published earlier this week.

November 20, 2007 - This research seems to be very well done and follows on the heels of similar work by the Yamanaka laboratory in mouse cells that was independently confirmed by other laboratories. The discovery that it is possible to reprogram adult human cells to pluripotency using a simple combination of genes is an important breakthrough...
August 29, 2007 - ...in this week's issue of the journal Nature, University of Michigan stem cell researcher Sean Morrison and his colleagues deal a mortal blow to the immortal strand, at least as far as blood-forming stem cells are concerned...
July 26, 2007 - A new study led by LSI’s Sean Morrison adds to mounting evidence that stem cells in the developing fetus are distinct from both embryonic and adult stem cells.
September 1, 2006 - The natural consequences of growing old include slower wound-healing and a brain that makes fewer new neurons because old tissues have less regenerative capacity. What has not been clear is why. A trio of papers published on-line Sept. 6 in the journal Nature shows that old stem cells don't simply wear out, they actively shut themselves down, probably as a defense against becoming cancerous from genetic defects that accumulate with age...

Apr. 5, 2006 - Morrison and other stem cell researchers at UM have found that certain cancers have their own stem cells, and have been able to identify differences between these malignant cells and normal stem cells for new cancer treatments.

June 30, 2005 - Scientists at the University of Michigan Medical School have discovered the biological equivalent of a grocery store bar code on the surface of primitive, blood-forming stem cells in mice. Called hematopoietic stem cells, they give rise to all the different types of specialized cells found in blood.

Oct. 22, 2003 - Scientists at the University of Michigan Comprehensive Cancer Center have identified a gene that controls the amazing ability of adult stem cells to self-renew, or make new copies of themselves, throughout life.

Aug. 14, 2002 - Scientists at the University of Michigan Medical School have found neural crest stem cells - primitive cells that generate the peripheral nervous system - in the gut of adult laboratory rats. The U-M discovery upsets the widely held belief that neural crest stem cells disappear in animals before birth, once the peripheral nervous system develops.
