WASHINGTON (AP -- Cells extracted from a human embryo have been nurtured into tiny blood vessels, a key step toward someday using embryonic stem cells to aid ailing hearts or fix blocked arteries, … ...

Scientists have grown a scalable new embryo-like model that unshrouds some mysteries of early human development, including blood cell formation, or hematopoiesis—a first for the field. In an ...

In a study published today in Cell Reports, we have shown how a lab simulation of an embryo’s beating heart and circulation lead to the development of human blood stem cell precursors.

Making stem cells from a patient’s adult cells – rather than human embryos – is one of the holy grails in modern medicine treatments. New research brings us two steps closer.

Unlike living tissue in the body, organoids lack a blood vessel system that delivers oxygen and nutrients to every cell. Beyond about 3 millimeters in diameter, an organoid can no longer sustain ...
