Stem cell study finds source of earliest blood cells during development

Summary:
Hematopoietic stem cells are now routinely used to treat patients with cancers and other disorders of the blood and immune systems, but researchers knew little about the progenitor cells that give rise to them during embryonic development. Scientists have now created novel cell assays that identified the earliest arising HSC precursors based on their ability to generate all major blood cell types (red blood cells, platelets and immune cells).

Hematopoietic stem cells are now routinely used to treat patients with cancers and other disorders of the blood and immune systems, but researchers knew little about the progenitor cells that give rise to them during embryonic development.

In a study published April 8 in Stem Cell Reports, Matthew Inlay of the Sue & Bill Gross Stem Cell Research Center, and faculty member of the Department of Molecular Biology and Biochemistry, and Stanford University colleagues created novel cell assays that identified the earliest arising HSC precursors based on their ability to generate all major blood cell types (red blood cells, platelets and immune cells).

This discovery of very early differentiating blood cells, Inlay said, may be very beneficial for the creation of HSC lines for clinical treatments. "The hope is that by defining a set of markers that will allow us to make purer, cleaner populations of these precursor cells, we'll be able to reveal the key molecular events that lead to the emergence of the first HSCs in development.

This could give us a step-by-step guide for creating these cells in a dish from pluripotent stem cell lines" added Inlay, who is an assistant professor of molecular biology & biochemistry at UC Irvine and conducted the study while a postdoctoral researcher in the Irving Weissman lab at Stanford.

The work was performed in collaboration with Thomas Serwold, now an assistant professor in the Joslin Diabetes Center at Harvard Medical School.

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

TheStreet (July 21, 2014) New research shows Gilead Science's drug Sovaldi helps in curing hepatitis C in those who suffer from HIV. In a medical study, the combination of Gilead's Hep C drug with anti-viral drug Ribavirin cured 76% of HIV-positive patients suffering from the most common hepatitis C strain. Hepatitis C and related complications have been a top cause of death in HIV-positive patients. Typical medication used to treat the disease, including interferon proteins, tended to react badly with HIV drugs. However, Sovaldi's %1,000-a-pill price tag could limit the number of patients able to access the treatment. TheStreet's Keris Lahiff reports from New York. Video provided by TheStreet
