7. What is a stem cell?

Stem cells are fascinating biological powerhouses! They are unique cells with the incredible ability to develop into many different cell types in the body, ranging from heart cells to nerve cells. What makes them special is their dual capacity for self-renewal – they can divide to form more stem cells – and differentiation, where they specialize into various cell types when needed for growth, repair, or development. In the real world, stem cells are at the forefront of cutting-edge medical research! They hold immense potential for treating a variety of diseases and injuries, such as Parkinson's disease, spinal cord injuries, and even heart disease. Researchers are exploring how to harness the regenerative potential of stem cells to develop therapies that could revolutionize healthcare, making them a cornerstone in the future of medicine.
