Scientists grow human blood vessels in lab for the first time

Scientists used stem cells to grow organoids in a Petri dish, which were then planted in mice, achieving a survival rate of over 95%. After six months, these organoids developed into human blood vessels with arteries and capillaries. Researchers believe these lab-grown blood vessels could aid in finding treatments and understanding the causes of various vascular diseases, including Alzheimer's, wound healing issues, and diabetes.
