Fat cells prolong survival of human stem cells grown in vitro

2013-04-10
(Press-News.org) New Rochelle, NY, April 9, 2013—One of the main obstacles that stands in the way of using human hematopoietic stem cells (hHSCs) to treat a variety of diseases is the difficulty growing them in culture—they quickly die or differentiate into other cell types. A series of experiments that demonstrate the successful use of fat cells as part of a feeder layer to support prolonged growth of hHSCs in culture is reported in an article in BioResearch Open Access, a bimonthly peer-reviewed open access journal from Mary Ann Liebert, Inc., publishers. The article is available on the BioResearch Open Access website.

In the article "Extending Human Hematopoietic Stem Cell Survival In Vitro with Adipocytes" Dean Liang Glettig and David Kaplan, Tufts University, Medford, MA included adipocytes (fat cells) in varying amounts and locations in the feeder layers of hHSCs being grown in the laboratory. They varied the concentrations of different cell types including adipocytes in the feeder layer, comparing different amounts of adipocytes, and evaluated the effect of direct cell-to-cell contact between the hHSCs and the adipocytes in the feeder layer on the survival rate of the hHSCs.

"The ability to prolong hHSC culture in vitro not only benefits basic stem cell research, it is also an important step towards developing advanced cell therapies for future clinical use," says BioResearch Open Access Editor Jane Taylor, PhD, MRC Centre for Regenerative Medicine, University of Edinburgh, Scotland.

UCLA researchers find potential link between auto pollution, some childhood cancers

2013-04-10
Scientists from UCLA's Fielding School of Public Health led by Julia Heck, an assistant researcher in the school's epidemiology department and a member of UCLA's Jonsson Comprehensive Cancer Center, have found a possible link between exposure to traffic-related air pollution and several childhood cancers. The results of their study — the first to examine air pollution from traffic and a number of rarer childhood cancers — were presented on April 9 in an abstract at the annual meeting of the American Association for Cancer Research in Washington, D.C. For the study, ...

Advancing secure communications: A better single-photon emitter for quantum cryptography

2013-04-10
ANN ARBOR—In a development that could make the advanced form of secure communications known as quantum cryptography more practical, University of Michigan researchers have demonstrated a simpler, more efficient single-photon emitter that can be made using traditional semiconductor processing techniques. Single-photon emitters release one particle of light, or photon, at a time, as opposed to devices like lasers that release a stream of them. Single-photon emitters are essential for quantum cryptography, which keeps secrets safe by taking advantage of the so-called observer ...

Class project inspires research article in Ecology

2013-04-10
A study that began as a class project among graduate students at the Virginia Institute of Marine Science is now a peer–reviewed research article in Ecology, the flagship journal of the Ecological Society of America. The article, "Physiological effects of diet mixing on consumer fitness: a meta-analysis," is co-authored by VIMS graduate students Jonathan Lefcheck, Matt Whalen, Theresa Davenport, and Josh Stone, along with VIMS Professor J. Emmett Duffy. Duffy teaches the Evolutionary Ecology course that inspired the students to pursue their research question: whether ...

Few to no work efficiencies when different providers read different scans on same patient

2013-04-10
According to a new study published online in the Journal of the American College of Radiology, any efficiencies in physician interpretation and diagnosis gained when different providers interpret different medical imaging scans performed on the same patient are minute and vary by procedure. Specifically, no potential intra-service work duplication was found when different exam interpretations were rendered by different physicians in the same group practice. Small potential efficiencies were found possible regarding pre- and post-service activities. Across all modalities ...

Defining the scope of skills for family medicine residencies

2013-04-10
BOSTON (April 9, 2013) — Medical school graduates entering one family medicine residency program might receive training that is markedly different than another family medicine residency program. While these new medical school graduates, called residents, will gain the clinical knowledge needed to practice medicine, their scope of skills depend on their specific experiences as residents. A team of healthcare professionals from the Family Medicine Residency Program at Tufts University School of Medicine have published a paper in the Journal of Graduate Medical Education that ...

Mayo Clinic, US and European researchers find heart disorder genetic variants in stillbirth cases

2013-04-10
ROCHESTER, Minn. -- In a first-of-its-kind study, researchers from the United States and Europe discovered genetic mutations associated with long QT syndrome (LQTS), a genetic abnormality in the heart's electrical system, in a small number of intrauterine fetal deaths, according to a study in the April 10 issue of the Journal of the American Medical Association. Researchers conducted a molecular genetic evaluation (referred to as a postmortem cardiac channel molecular autopsy) in 91 cases of unexplained fetal death (stillbirths) from 2006-2012. They discovered the prevalence ...

2013-04-10
Cambridge, MA, April 9, 2013– BIND Therapeutics, a clinical-stage biopharmaceutical company developing a new class of highly selective targeted and programmable therapeutics called AccurinsTM, announced today that positive Phase 1 clinical data for BIND-014, the company's lead drug candidate, were presented today in an oral presentation at the American Association for Cancer Research (AACR) 2013 Annual Meeting. Clinical investigators presented the Phase 1 results with BIND-014, its targeted docetaxel Accurin, in 28 heavily-pretreated patients with advanced or metastatic ...

Reliably higher levels of healthy compound in Beneforte broccoli

2013-04-10
Field trials and genetic studies have shown that a new variety of broccoli reliably yields higher levels of a health-promoting compound. Broccoli contains a compound called glucoraphanin, which has been shown to promote health by maintaining cardiovascular health and a reduction in the risk of cancer. A long term breeding programme to increase glucoraphanin levels has resulted in the commercial release of Beneforté broccoli. Beneforté was developed by crossing standard broccoli with a wild relative derived from Sicily. Publicly funded research to develop Beneforté broccoli ...

Take a kidney transplant now or wait for a better one? Hopkins researchers create 'decision' tool

2013-04-10
Johns Hopkins scientists have created a free, Web-based tool to help patients decide whether it's best to accept an immediately available, but less-than-ideal deceased donor kidney for transplant, or wait for a healthier one in the future. Historically, the researchers say, it has been difficult, if not impossible, to accurately quantify the risk of accepting a deceased-donor kidney that may have been infected by hepatitis C, as compared to waiting what could be months or years for a better organ. There is a 5 to 15 percent chance of dying every year on the waiting list. ...
