This document discusses stem cell research and its potential for cures. It defines stem cells as cells that can differentiate into specific cell types and divide through mitosis. There are two main types of stem cells: embryonic stem cells obtained from blastocysts and adult stem cells found in tissues. The document notes that stem cells function as the repair system of the body by regenerating tissues. It highlights the potential of stem cell research to develop treatments and cures for diseases like diabetes, Parkinson's, and spinal cord injuries by replacing damaged cells.
