Study Finds Phenotypic Plasticity Among Melanoma Cells |

17. November 2010 05:48 - University of Michigan researchers have determined that most types of melanoma cells can form malignant tumors, providing new evidence that the deadliest form of skin cancer does not conform to the increasingly popular cancer stem cell model. In addition, the researchers found that melanoma tumor cells can change their appearance by switching various genes on and off, making the malignant cells a stealthy, shape-shifting target for researchers seeking new treatments, according to a team led by Sean Morrison, director of the U-M Center for Stem Cell Biology. Both findings fly in the face of the cancer stem cell model, which states that a handful of rare melanoma stem cells drive the formation, growth and progression of malignant tumors in many cancers. Some supporters of the model have suggested that melanoma might be more effectively treated by taking aim specifically at these rare cancer stems cells, rather than attempting to eliminate all melanoma cells.

HemaCAM Computer-Assisted Blood Cell Analysis System Automates Assessment of Blood Counts |

11. November 2010 06:12 - If a blood count is abnormal, the medical laboratory scientist (MLS) has to manually perform a differential blood count analysis. This costs time and money. The computer-assisted blood cell analysis system HemaCAM by the company Horn has recently been launched on the market and does just this. At the MEDICA 2010 trade fair, which is being held from November 17 to 20 in Düsseldorf, Germany, scientists from the Fraunhofer Institute for Integrated Circuits IIS will be presenting this intelligent microscopy system at joint stand F05 in hall 10. The patient feels drawn and tired, keeps having a high temperature even after recovering from cold some time ago. The doctor suggests performing a differential blood count to try to determine the cause. He takes some blood and has it analyzed in the laboratory - a routine procedure in medical diagnostics. In a differential blood count the leukocytes, the white blood cells, are quantitatively and qualitatively assessed. The values obtained assist further diagnosis and are important indicators for disorders such as inflammations, allergies as well as parasitic or autoimmune diseases. Usually blood samples are analyzed with the aid of blood counting machines. However, if abnormalities are seen in the sample the MLS must assess the abnormal cells manually - a very time-consuming method. For the trained specialist at the microscope this means counting, counting and more counting.

San Francisco Chronicle, October 26, 2010 Global Flow Cytometers Market to Exceed US$2.0 Billion by 2015, According to a New Report by Global Industry Analysts, Inc. High-precision flow cytometry market was minimally affected during 2008 and 2009 by the recent global meltdown. Flow cytometry is expected to witness significant growth in the coming years driven by factors such as potential applications in immunology, biochemistry, microbiology, cytogenetics, chemical engineering, agronomy, molecular biology, and cytology. Further, technological advances and innovations in stem cell research, monoclonal antibodies, computers, electronics, and fluorochrome chemistry are likely to fuel growth in the market. Clinical labs are conventional growth drivers while research segment, spurred by increasing use in pharmaceutical, biotech and discovery tools companies, is expected to be the major factor driving growth in the next few years.
