Photo: Lab mouse [16/11/2015] Johns Hopkins researchers report that a new study of mouse cells has revealed reasons why attempts to grow stem cells to maturity in the laboratory often fail, and provided a possible way to overcome such "developmental arrest."Roadblocks to lab-grown stem cells' maturation - Read more

Novel stem cell line avoids risk of introducing transplanted tumors

Photo: micrograph, embryonic rat kidney cell [12/11/2015] Human pluripotent stem cells (hPSC) can become any type of cell in the adult body, offering great potential in disease modeling, drug discovery and creating replacement cells for conditions ranging from cardiovascular to Alzheimer's disease.Novel stem cell line avoids risk of introducing transplanted tumors - Read more

Strangled cells condense their DNA

Photo: DNA in a cell [11/11/2015] Scientists at the Institute of Molecular Biology (IMB) have been able to see, for the first time, the dramatic changes that occur in the DNA of cells that are starved of oxygen and nutrients. The findings provide new insight into the damage these diseases cause and may help researchers to discover new ways of treating them.Strangled cells condense their DNA - Read more

Using microfluidic devices to sort stem cells

Photo: micropipet for analyzing stem cells [10/11/2015] While there are no cures for neurological diseases such as Alzheimer's and Parkinson's, many researchers believe that one could be found in neural stem cells. Unfortunately, scientists do not yet have a full understanding of how these cells behave and differentiate, which has put a roadblock in the path to potential life-saving treatments.Using microfluidic devices to sort stem cells - Read more

Image: genetics structure [02/11/2015] Oxford University researchers have found the Achilles heel of certain cancer cells - mutations in a gene called SETD2. Their findings will be presented to the National Cancer Research Institute conference in Liverpool this Monday.Treatment targets cancers with genetic signature - Read more

First synthetic model of a bacterial outer membrane will support antibiotic development

Graphic: bacteria in a petri dish [22/10/2015] For the first time researchers from Newcastle University and the Science and Technology Facilities Council have produced a working model giving access to unprecedented information about the bacteria which is notoriously hard to study due to its size and complex exterior. First synthetic model of a bacterial outer membrane will support antibiotic development - Read more

3-D cell growth opens pathway for spinal cord repair

Photo: Raja Vadivelu [21/10/2015] Griffith University researchers have opened a new avenue to advance a therapy to repair the paralysed spinal cord. A paper published in the prestigious Nature group journal "Scientific Reports" presents a novel technique to grow cells in three dimensions, without the traditional restrictions of matrix or scaffolds.3-D cell growth opens pathway for spinal cord repair - Read more

Scientists convert skin cells into placenta-generating cells

Image: A trophoblast stem cell [15/10/2015] Regenerative medicine aims to replace lost or damaged cells in the human body through cellular transplantation. Embryonic stem cells (ESCs) are pluripotent cells that are capable of long-term growth, self-renewal, and can give rise to every cell, tissue and organ in the fetus's body. Two major bottlenecks to realizing such potential are allogenic immune rejection by recipients and ethical issues.Scientists convert skin cells into placenta-generating cells - Read more

Genes linked with malaria's virulence shared by apes and humans

( Source: MEDICA.de )

Photo: Malaria fly [12/10/2015] The malaria parasite molecules associated with severe disease and death have been shown to share key gene segments with chimp and gorilla malaria parasites, which are separated by several millions of years, according to a new study led by Harvard T.H. Chan School of Public Health. This could aid in basic understanding of the causes of malaria and provide targets for drugs and vaccines.Genes linked with malaria's virulence shared by apes and humans - Read more
