Human cell culture

Human cell culture is a laboratory process that involves growing human cells outside of the body under controlled conditions. Scientists isolate cells from tissues or blood, then place them in a nutrient-rich environment called a culture medium, which supplies essential nutrients, oxygen, and growth factors. This setup allows the cells to multiply and behave as they would inside the body. Cell culture is essential for medical research, drug testing, and developing treatments, providing a safe, reliable way to study human cells' functions, responses, and diseases without needing to experiment directly in living organisms.
