Flow Cytometry News and Research

RSS

Flow cytometry is a technique for counting and examining microscopic particles suspended in a stream of fluid. It allows simultaneous multiparametric analysis of the physical and/or chemical characteristics of single cells flowing through an optical and/or electronic detection apparatus.

Does HBV infection induce acute cellular DNA damage?

Eukaryotic cells employ multiple strategies of checkpoint signaling and DNA repair mechanisms to monitor and repair damaged DNA.

Battling cancer at the single cell level

New research suggests that the identification and examination of key cell signaling events required for initiation and progression of cancer might be best accomplished at the single cell level. The research, published by Cell Press in the October issue of the journal Cancer Cell, provides new insight that may lead to better diagnosis and treatment of some complex cancers.

Discovery of important fat precursor cell

To understand where fat comes from, you have to start with a skinny mouse. By using such a creature, and observing the growth of fat after injections of different kinds of immature cells, Rockefeller University scientists have discovered an important fat precursor cell that may in time explain how changes in the numbers of fat cells might increase and lead to obesity.

Next-generation nanomedicine

In an article featured on the cover of the March issue of Nature Nanotechnology, Mauro Ferrari, Ph.D., of The University of Texas Health Science Center at Houston, presented a proof-of-concept study on a new multistage delivery system (MDS) for imaging and therapeutic applications. This discovery could go a long way toward making injectable drugs more effective.

High-fat diet makes mice susceptible to liver injury

A high fat diet may kill regulatory T cells in the liver, allowing steatosis (simple fatty liver) to develop into steatohepatitis (fatty liver with inflammation), according to the results of a new study in the November issue of Hepatology, a journal published by John Wiley & Sons on behalf of the American Association for the Study of Liver Diseases (AASLD).
