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.

Amnis receives patent for blood and cell analysis using an imaging flow cytometer

Amnis Corporation, a manufacturer of advanced cell imaging systems, announced today that it has received U.S. patent 7,522,758.

New understanding of roles of insulin in obesity or type II diabetes

Researchers have uncovered new evidence suggesting factors other than genes could cause obesity, finding that genetically identical cells store widely differing amounts of fat depending on subtle variations in how cells process insulin.

Scientists measure impact of high-fat diet on the spread of cancer

Researchers at Purdue University have precisely measured the impact of a high-fat diet on the spread of cancer, finding that excessive dietary fat caused a 300 percent increase in metastasizing tumor cells in laboratory animals.

B-cell clones as early markers for chronic lymphocytic leukemia

Testing of blood specimens may detect abnormal white blood cells in patients years before the chronic form of lymphocytic leukemia (CLL) develops, according to research published in the current issue of the New England Journal of Medicine.

An adjuvant chemotherapeutic agent in gastric cancer therapy

Peritoneal carcinomatosis can be thought of as a series of events that together form a peritoneal metastatic cascade.

New test for mysterious metabolic diseases

Scientists at Stanford University School of Medicine have devised a much-needed way to monitor and find treatments for a mysterious and devastating group of metabolic diseases that arise from mutations in cells' fuel-burning mechanism.

Discovery of new regulatory circuit controlling immune cell production in mice

Using a mouse model, researchers have shown that elevated levels of a small protein known as interleukin 7 (IL-7) plays a central role in regulating the production of a type of white blood cell that is required for effective immune responses.

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.

New rapid test for rare leukemia

A new twist on a well-known cell sorting technique may allow physicians to diagnose rare leukemias in hours instead of weeks, according to a study by researchers at the Stanford University School of Medicine and UC-San Francisco.

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.
