Artificial bone marrow may be used to reproduce hematopoietic stem cells. A prototype has now been developed by scientists of KIT, the Max Planck Institute for Intelligent Systems, Stuttgart, and Tübingen University (Germany). The porous structure possesses essential properties of natural bone marrow and can be used for the reproduction of stem cells at the laboratory. This might facilitate the treatment of leukemia in a few years.

In a prime example of finding new uses for older drugs, studies in zebrafish show that a 50-year-old antipsychotic medication called perphenazine can actively combat the cells of a difficult-to-treat form of acute lymphoblastic leukemia (ALL). The drug works by turning on a cancer-suppressing enzyme called PP2A and causing malignant tumor cells to self-destruct.

The information that clinicians provide to patients when prescribing treatments has long been thought to play a role in the way that patients respond to drug therapies. Now an innovative study of migraine headache confirms that a patient's expectations - positive, negative or neutral - influence the effects of both a medication and a placebo.

Researchers have developed a technique for creating nanoparticles that carry two different cancer-killing drugs into the body and deliver those drugs to separate parts of the cancer cell where they will be most effective. The technique was developed by researchers at North Carolina State University and the University of North Carolina at Chapel Hill.

A plant used for centuries as a pain reliever in Chinese medicine may be just what the doctor ordered, especially when it comes to chronic pain. A key pain-relieving ingredient is a compound known as dehydrocorybulbine (DHCB) found in the roots of the flowering plant Corydalis, a member of the poppy family, according to researchers who report their findings in the Cell Press journal Current Biology on January 2.

The United States' global share of biomedical research spending fell from 51 percent in 2007 to 45 percent in 2012, while Japan and China saw dramatic increases in research spending. The research and development spending in the United States dropped from $131 billion to $119 billion, when adjusted for inflation, from 2007-2012, while Japan increased spending by $9 billion and China increased by $6.4 billion.

Scientists from The University of Manchester - part of Manchester Cancer Research Centre believe they have discovered a new way to make chemotherapy treatment more effective for pancreatic cancer patients. Pancreatic cancer is an aggressive cancer with poor prognosis and limited treatment options and is highly resistant to chemotherapy and radiotherapy.
