A team of researchers is set to grow miniature livers in space, using microgravity to encourage the growth of healthy tissue with an ample blood supply. The experiment aims to potentially lead to personalized, space-grown tissues and organs for use in transplant surgeries. Microgravity could help overcome challenges faced when growing tissues on Earth, where gravity pulls cells into contact with the bottom of a plate or dish.
