Scientists identify pancreatic cancer stem cells
02-01-2007 · EurekAlert!Researchers at the University of Michigan Medical Center have, for the first time, identified human pancreatic cancer stem cells. Their work indicates that these cells are likely responsible for the aggressive tumor growth, progression, and metastasis that define this deadly cancer.

- Cancer stem cell subpopulation drives metastasis of human pancreatic cancer
09-12-2007 · EurekAlert!
Scientists have identified a distinct subpopulation of cancer stem cells (CSCs) that is responsible for metastasis of a deadly human pancreatic cancer. The research, published by Cell Press in the Sept. issue of the journal Cell Stem Cell, provides insight into the role of CSCs in cancer initiation, progression and metastasis, and suggests new directions for development of more effective therapeutics.

- Scientists identify a mouse embryonic stem cell more like our own
06-27-2007 · EurekAlert!
Scientists have discovered a new type of mouse embryonic stem cell that is the closest counterpart yet to human embryonic stem cells, the National Institutes of Health announced today. The cells are expected to serve as an improved model for human ES cells in studies of regeneration, disease pathology and basic stem cell biology.

- Algae Provide New Clues To Cancer
10-13-2006 · ScienceDaily
A microscopic green alga helped scientists at the Salk Institute for Biological Studies identify a novel function for the retinoblastoma protein (RB), which is known for its role as a tumor suppressor in mammalian cells. By coupling cell size with cell division, RB ensures that cells stay within an optimal size range.

- Cancer stem cells can go it alone
06-11-2007 · EurekAlert!
At the heart of most, if not all cancers, lie a handful of wayward stem cells that feed the ever growing tumor mass, but their scarcity make it difficult for scientists to study them. Now, times of plenty may lie ahead as a breast cancer cell line -- established long ago -- turned out to behave a lot like cancer stem cells.
