New insights into how cells stick to each other and to other bodily structures

Research carried out by scientists at the Georgia Institute of Technology and The University of Manchester has revealed new insights into how cells stick to each other and to other bodily structures, an essential function in the formation of tissue structures and organs. It's thought that abnormalities in their ability to do so play an important role in a broad range of disorders, including cardiovascular disease and cancer.

Pairing Avastin with dasatinib can stop lethal spread of glioblastoma multiforme

The drug bevacizumab, also known by the trade name Avastin, shrinks tumors briefly in patients with an aggressive brain cancer known as glioblastoma multiforme, but then they often grow again and spread throughout the brain for reasons no one previously has understood. Now, Mayo Clinic researchers have found out why this happens.

Biomaterials as neural stem cell niches can help repair damage in the CNS

Despite recent advances in understanding the mechanisms of nerve injury, tissue-engineering solutions for repairing damage in the central nervous system (CNS) remain elusive, owing to the crucial and complex role played by the neural stem cell (NSC) niche. This zone, in which stem cells are retained after embryonic development for the production of new cells, exerts a tight control over many crucial tasks such as growth promotion and the recreation of essential biochemical and physical cues for neural cell differentiation.

MDGA proteins associated with autism suppress inhibitory synapse formation

Synapse development is promoted by a variety of cell adhesion molecules that connect neurons and organize synaptic proteins. Many of these adhesion molecules are linked to neurodevelopmental disorders; mutations in neuroligin and neurexin proteins, for example, are associated with autism and schizophrenia.

Reviewing the latest methods for characterizing biomaterials

Biomaterials and medical devices must be rigorously tested in the laboratory before they may be implanted into test subjects. By ensuring that these test methods are both quick and efficient, an increased number of materials can be tested and working implants can be produced more rapidly. The development of such tests is therefore essential to biomedical advancement, and Characterization of biomaterials reviews the latest methods for defining properties and characterizing materials. Characterization of biomaterials discusses a wide array of techniques and various unique approaches to the problems faced in characterizing biomaterials, whilst also providing information on standards and methods for assessing the safety and biocompatibility of biomaterials.

Scientists isolate cancer stem cells that lead to growth of Wilms' tumours

Scientists have isolated cancer stem cells that lead to the growth of Wilms' tumours, a type of cancer typically found in the kidneys of young children. The researchers have used these cancer stem cells to test a new therapeutic approach that one day might be used to treat some of the more aggressive types of this disease.

Autism associated with reductions in cellular adhesion molecules in the blood

A new study published in Biological Psychiatry suggests that autism is associated with reductions in the level of cellular adhesion molecules in the blood, where they play a role in immune function.

New insights into how MSCs ‘traffic’ from the circulation into tissues

Mesenchymal stem cells (MSCs), are a newly emerging cellular therapy being tested in approximately 250 clinical trials worldwide to help repair damaged tissues, such as injured heart muscle following a heart attack. The problem is that when culture-expanded MSCs are injected into the circulation, they have trouble gaining access to the inflamed tissues-exactly where their help is needed.

CD22 protein could prove to be important new target for anti-cancer therapy

A team of UC Davis investigators has discovered a protein on the surface of lung cancer cells that could prove to be an important new target for anti-cancer therapy. A series of experiments in mice with lung cancer showed that specific targeting of the protein with monoclonal antibodies reduced the size of tumors, lowered the occurrence of metastases and substantially lengthened survival time.

Researchers identify how mosquito's immune system attacks specific infections

Researchers at the Johns Hopkins Bloomberg School of Public Health have determined a new mechanism by which the mosquitoes' immune system can respond with specificity to infections with various pathogens, including the parasite that causes malaria in humans, using one single gene.

Tight-junction proteins could help pin down hemorrhagic transformation risk

Study findings suggest that measuring levels of tight-junction proteins in the blood of patients with stroke may help to gauge their risk for hemorrhagic transformation.

Thomson Reuters names Sanford-Burnham cancer researcher among 2012 Citation Laureates

Thomson Reuters has selected Erkki Ruoslahti, M.D., Ph.D., cancer researcher and distinguished professor at Sanford-Burnham Medical Research Institute (Sanford-Burnham), as one of its 2012 Citation Laureates. Citation Laureates are scientists that Thomson Reuters has predicted to win the Nobel Prize.

PCA inhibits multiple pathways involved in development of diabetic nephropathy

Diabetic nephropathy is one of the most serious complications related to diabetes, often leading to end-stage kidney disease. Purple corn grown in Peru and Chile is a relative of blue corn, which is readily available in the U.S.

Potential new COPD drug

A study led by researchers at Boston University School of Medicine (BUSM) has shown that a compound used in some skin creams may halt the progression of emphysema and reverse some of the damage caused by the disease. When the compound Gly-His-Lys (GHK) was applied to lung cells from patients with emphysema, normal gene activity in altered cells was restored and damaged aspects of cellular function were repaired.

Mice have different neural subsystem associated with instinctually important smells

A new study finds that mice have a distinct neural subsystem that links the nose to the brain and is associated with instinctually important smells such as those emitted by predators. That insight, published online this week in Proceedings of the National Academy of Sciences, prompts the question whether mice and other mammals have specially hardwired neural circuitry to trigger instinctive behavior in response to certain smells.

Super-resolution microscopy highlights bacterial biofilms

A multi-fluorescent labeling strategy combined with super-resolution light microscopy has allowed researchers to observe the development of a bacterial biofilm in realtime.

New method enhances adhesion of injected CECs for successful corneal transplantation

Regenerative medicine, or the use of specially grown tissues and cells to treat injuries and diseases, has been successful in treating disorders of a number of organs, including heart, pancreas, and cartilage. However, efforts to treat disorders of the corneal endothelium, a single cell layer on the inner surface of the cornea, with regenerative techniques have been less effective. Now, a group of scientists has developed a method that enhances the adhesion of injected corneal endothelial cells (CECs), allowing for successful corneal transplantation to repair pathological dysfunctions.

Higher quality bone from stem cells

UCLA stem cell scientists purified a subset of stem cells found in fat tissue and made from them bone that was formed faster and was of higher quality than bone grown using traditional methods, a finding that may one day eliminate the need for painful bone grafts that use material taken from the patient during invasive procedures.

Powerful new tools can study glycans’ function

Scientists at The Scripps Research Institute have developed chemical compounds that can make key modifications to common sugar molecules ("glycans"), which are found on the surface of all cells in our body. The new study presents powerful new tools for studying these molecules' function, for example in cell signaling and immunity, and for investigating new treatments for chronic inflammation, autoimmune diseases, cancer metastasis, and related conditions.
