Heart diseases are the leading cause of death in the United States killing more than 600,000 people a year. A team of researchers at the University of Minnesota has 3D printed a functioning human heart pump in the lab, which could help save the lives of thousands of patients.

According to the Science Daily website, the researchers used a type of stem cells with the potential to develop into any type of cell in the body, in addition to a mix of proteins, and the printer's ink.

The heart muscle model is about 1.5 centimeters long and was specifically designed to fit into the abdominal cavity of a mouse for further study, the German News Agency reported.

The team said the new muscle can be used to study the functions of the heart, and the problems that might affect it.

Brenda Ogle from the Department of Biomedical Engineering in the University of Minnesota College, said this is a critical advance in heart research because this new study shows how we were able to 3D print heart muscle cells in a way that the cells could organize and work together.

"We now have a model to track and trace what is happening at the cell and molecular level. We can introduce disease and damage into the model and then study the effects of medicines and other therapeutics," she explained.

Kate, the Princess of Wales, is set to present the trophy to the winner of the women's singles final at Wimbledon on Saturday after opting not to attend the match last year while she was recovering from cancer.

The All England Club said Kate, the wife of Prince William, will be back in the Royal Box on Center Court for the match between eighth-seeded Iga Swiatek and No. 13 Amanda Anisimova. She will then take part in the on-court trophy presentation, The AP news reported.

Kate has been the patron of the All England Club since 2016 and has regularly attended the men's and women's finals. However, she was not there when Barbora Krejcikova defeated Jasmine Paolini for the women's title last year.

She did hand the trophy to Carlos Alcaraz after his victory over Novak Djokovic in the men's final, when she made only her second public appearance since announcing she was diagnosed with cancer.

She has been gradually returning to public duties since since announcing last fall that she had completed chemotherapy, and took part in welcoming French President Emmanuel Macron during his state visit to Britain this week.
