Adult stem cells are undifferentiated cellsfound throughout the body after development, that multiply by cell division to replenish dying cells and regenerate damaged tissues. Scientific interest in adult stem cells is centered on their ability to divide or self-renew indefinitely, and generate all the cell types of the organ from which they originate, potentially regenerating the entire organ from a few cells. They have mainly been studied in humans and model organisms such as mice and rats.

Jump to navigation. An adult stem cell is thought to be an undifferentiated cell, found among differentiated cells in a tissue or organ. The adult stem cell can renew itself and can differentiate to yield some or all of the major specialized cell types of the tissue or organ.

Stem cells are the foundation for every organ and tissue in your body. There are many different types of stem cells that come from different places in the body or are formed at different times in our lives. These include embryonic stem cells that exist only at the earliest stages of development and various types of tissue-specific or adult stem cells that appear during fetal development and remain in our bodies throughout life.

Stem cells and derived products offer great promise for new medical treatments. Learn about stem cell types, current and possible uses, ethical issues, and the state of research and practice. You've heard about stem cells in the news, and perhaps you've wondered if they might help you or a loved one with a serious disease.

The derivation of embryonic stem cell lines is banned but it is permitted to use imported embryonic stem cell lines for research. Under this law, the embryo is recognized as a subject of rights from the moment of fertilization. The law prohibits the use of embryos for any research unless it is specifically aimed towards improving the therapeutic and medical condition of the embryo concerned.

Most cells in the body are differentiated cells. These cells can only serve a specific purpose in a particular organ. For example, red blood cells are specifically designed to carry oxygen through the blood.

Fortino, Jordan Greenberg and Herman S. Pluripotent Stem Cells. Stem cells are undifferentiated cells defined by their abilities to self-renew and differentiate into mature cells. Stem cells found in fully developed tissues are defined as adult stem cells.

A cancer scare helped encourage stem cell researcher Paul Knoepfler to become an outspoken watchdog over his field. The parents of a year-old with a degenerative eye disease wonder whether there's any hope of averting blindness with a stem cell injection. Knoepfler, though housed in the Shriners Hospitals for Children here, isn't a physician.

Adult stem cells are undifferentiated cells found throughout the body that divide to replenish dying cells and regenerate damaged tissues. Research into adult stem cells has been fueled by their abilities to divide or self-renew indefinitely and generate all the cell types of the organ from which they originate — potentially regenerating the entire organ from a few cells. Unlike embryonic stem cells, the use of adult stem cells in research and therapy is not controversial because the production of adult stem cells does not require the destruction of an embryo. The rigorous definition of a stem cell requires that it possesses two properties: Self-renewal - the ability to go through numerous cycles of cell division while maintaining the undifferentiated state.
