New hope for heart patients
Your support helps us to tell the story
From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

People dying from cardiovascular disease could stay alive for many years longer after the first clinical evidence was revealed yesterday that hearts can be repaired using bone-marrow stem cells.
US scientists compared two groups of heart bypass patients, one of which was treated with stem cells taken from their hip bones. Six months later, the hearts of the stem-cell group were pumping more blood than those of patients who had surgery alone. Professor Robert Kormos, who heads the University of Pittsburgh team which led the study, said: "It will revolutionise our approach, which is largely palliative, to one that is truly regenerative."
Stem cells are immature cells that can be programmed to become different kinds of tissue. Studies show that certain stem cells taken from bone marrow have the potential to influence heart muscle and blood vessel growth.
The findings were presented at a meeting in Toronto of the American Association for Thoracic Surgery.
