Many people don't know the difference between different types of stem cells and their potential uses in the development of treatments for a multitude of illnesses and disease processes. Stem cells from different part of the body are identified by different names. For example, embryonic stem cells come from embryonic or fetal tissues, while placenta stem cells are cultivated from the placenta after the birth of an infant. Umbilical cord stem cells are cultivated from the umbilical cord following the birth process. Adult stem cells may be cultivated from skin, organ, and blood tissues cultivated from an adult.

Placenta stem cells therapy is one of the newest developments in the field of stem cell research. Placenta implants, stem cell therapies, and stem cell implants have been used in recent years to help treat and even cure a multitude of illness and disease processes including memory problems, chronic infections, chronic fatigue syndrome, and illnesses or conditions related to stress and anxiety.

There are over 3 trillion cells found in the human body that might potentially be used for future medical treatments. Stem cell therapies treat all body organ systems, including muscle tissues, the brain, lung, heart and liver. Each stem cell also contains specific instructions on how it replicates and functions, as well as how long a specific cell will live. Some stem cells are constantly being replaced, while others last a lifetime. For example, brain cells may last a lifetime, while blood cells are replaced every day.
