The photograph won the first prize by the jury voted for Fraser Macrae, researchers from the University of Leeds (UK). The photo was taken under electron microscope and magnified 5,000 times showing a red heart-shaped blood cell in the fibers of a fibrin clot. Fraser Macrae said he found the red blood cells were squeezed by blood fibrillation while studying the structure and formation of blood clots.

The photo was awarded first prize by Facebook users: "Inside the artery", taken by Dr. Matthew Lee from Strathclyde University (Scotland). The photo shows the endothelium, a complex network of cells inside the same vein. The endothelial cells (expressed in purple in the figure) act as a linkage network, like a modern telecommunication system, to detect and transmit signals. Dr. Mathew Lee and his colleagues have developed a new imaging system to simulate signals sent from within the arteries.

"Flower in the Heart" by Dr. Nicoletta Surdo - Oxford University. This is considered to be the most impressive photo of this year. In this picture, the fibers of a rat's heart muscle form a rose beneath the microscope. The photo contest was first held in 2005 to honor the cardiologists sponsored by BHF. All participating images are taken electronically with the latest state-of-the-art microscope, giving people a different perspective on the research process of scientists.

"Storm" was taken by Dr. Tamara Gibri - Queen Mary University in London. The photo shows that the immune system is working in the muscles. When bacteria and viruses enter the body (acute infection), neutrophils (shown in pink) will appear in the blood and break down blood vessels (blue and green) to destroy these microorganisms.

This image shows a dense vein in the heart of the adult zebra fish. The photo was taken by Dr. Yujie Yang from Edinburgh University. The awards will be judged and evaluated by jury members. For the first time this year, the contest will include additional prizes selected by users via BHF's Facebook page.

Photo by Dr. Marcela Rosas, Cardiff University shows a fibroblast in the cultured environment. Fibroblast is the most common type of cell found in connective tissue, in the shape of stars, which participates in the process of scar formation and healing injury.

This image, taken by Dr. Simon Wilson of the University of Edinburgh, shows that a blood clot forms in the bloodstream of a healthy person. Platelets (green) make up most of the blood clots with fibrous (red) fibers attached to the walls of blood vessels.

A mirror image of the mitochondrion in the mouse embryo is in the shape of a butterfly. The picture was taken by Dr. Nicoletta Surdo of Oxford University.

"Heart in heart"- a cross section of the veins of a rat shaped like a heart. The photo was taken by Dr. Sean Davidson of University College London while conducting research on signaling to protect the heart and blood vessels from damages.
