The immune system is complex and a number of genetic diseases are attributed to defects in the cells that form its origins. The study from Lund and Oxford University presents unique findings on the formation of these cells. We know that the first blood stem cells are formed in the aorta region and then travel to the liver, which is the body’s major blood-forming organ during the fetal stage…
"We know that humans have a number of different community structures in the gut. When you think about it, maybe different people – independent of their genetics – might be predisposed," says Joseph Zackular of the University of Michigan, an author on the study…
This is an unexpected finding, as some cancers keep this pathway turned on to fuel their unchecked growth and expansion. …
The protein c-MYC is referred to as a master regulator because it controls the activity of hundreds of genes, including many that drive cell growth and cell proliferation. …
There is no fast and easy way to diagnose these clots, which often remain undetected until they break free and cause a stroke or heart attack. However, new technology from MIT may soon change that: A team of engineers has developed a way to detect blood clots using a simple urine test. The noninvasive diagnostic, described in a recent issue of the journal ACS Nano, relies on nanoparticles that detect the presence of thrombin, a key blood-clotting factor…
Chromosomes are thread-like structures inside cells that carry genes and function in heredity. Human chromosomes each contain a single piece of DNA, with the genes arranged in a linear fashion along its length. …

Published in Nature Cell Biology, the new study focuses on the process that occurs when cancer cells interact with healthy cells in order to migrate around the body during metastasis. Scientists know that cancer cells recruit healthy cells and use them to travel long distances, but how this process takes place and how it could be controlled to design new therapies against cancer remains unknown. Now, using embryonic cells called ‘neural crest cells’ (which are similar to cancer cells in term of their invasive behaviour) and placode cells which are the precursors for cranial nerves (the equivalent to healthy cells) researchers at UCL have started to unravel this process. They have found that when neural crest cells are put next to placode cells they undergo a dramatic transformation and start ‘chasing’ the placode cells…
The transformation of sedentary, specialized cells into wandering, invasive, and unspecialized cells is called epithelial-mesenchymal transition (EMT), which is central to metastasis. EMT is a multistage process, which is accompanied by a fundamental change in cell morphology and number of genetic programs. The molecular processes that govern EMT, however, are still poorly understood. Main Switch Found The research groups of Prof. …
