A scaffold crafted from pig bladder and implanted in patients’ severely injured legs spurred stem cells to make muscle and improve limb function, a method that may change the standard of care.
Japan’s Riken research center said some data were falsified in a pair of studies that had outlined a simpler, quicker way of making stem cells.
Six months ago, Roche Holding AG scientists disrupted the rhythmic beating of heart muscle made from stem cells by adding a cancer drug to it, duplicating in the laboratory a side effect previously only seen in patients.
Scientists have created embryonic stem cells that are a near identical genetic match to patients, an advance that could enable transplants and treatments based on an individual’s own tissues.
Heather Von St. James, 45, remembers her father, a demolition worker, coming home covered in dust and dirt. Still, she’d hug him each night and, sometimes, put on his coat and shoes to play.
