Studies on stem cells continue to advance knowledge on the way an organism develops from one cell and how damaged cells in adult organisms are replaced with healthy cells. While stem cell research is a fascinating of modern biology, it raises scientific questions while it generates new discoveries.

Laboratory research of stem cells let researchers learn about the essential properties of cells and what makes them different from specialised types of cells. Stem cells have already been used in laboratories for screening new drugs and developing model systems. These are meant to study normal growth and identify birth defect causes.
