Introduction
The liver, which is positioned below the right lung and under the ribcage is one of the largest organs of the human body. The liver has two large sections, called the right and the left lobes.The liver nonstop filters blood that circulates through the body, converting nutrients and drugs absorbed from the digestive tract into ready-to-use chemicals. The liver performs many other important functions, such as removing toxins and other chemical waste products from the blood and readying them for excretion.

There are many types of liver diseases .Liver cancer is one of them. Liver cancer, also known as hepatic cancer which is a cancer that starts in the liver, and not from another organ which eventually migrates to the liver. The liver can be affected by primary liver cancer, which arises in the liver, or by cancer which forms in other sites and then spreads to the liver. Primary liver cancer, which starts in the liver, accounts for about 2% of cancers in the U.S but up to half of all cancers in some undeveloped countries. In the U.S primary liver cancer strikes twice as many men as women, at an average age of 67(Web Med)(n.d.).Most liver cancer is secondary or metastatic, meaning it started elsewhere in the body. Cancers that originate elsewhere and eventually reach the liver are known as liver metastasis or secondary liver cancer. (medicalnewstoday,2009). The liver is made up of several different types of cells, several types of tumors can form in the liver. Some of these are benign (noncancerous), and some are cancerous and can spread to other parts of the body (metastasize). These tumors have different causes and are treated differently.
Human Embryonic Stem Cells Differentiating into Liver Cells, California Institute of Regenerative Medicine Liver failure is a growing health problem and one of the main causes of death worldwide. Discovery of stem cells reveals that they are capable of differentiating into specialized cell types, including the hepatocytes, by utilizing these hepatocytes damaged liver can be re-generated .Scientists have paid their attention to the field of stem cells, which has helped to understand the pathogenesis of liver disease.Liver like cells derived from bone marrow and embryonic stem cells, results in better understanding of the biochemical compounds that are essential in liver development. Patients with advanced liver disease can be treated with stem cells taken from their own skin or blood in a breakthrough that could save thousands of lives. Stem cells are a class of undifferentiated cells that are able to differentiate into specialized cell types. Stem Cell Therapy is the process of injecting undifferentiated cells into an organism in the hopes that the cells will differentiate into the same type of cell as the damaged cells and replace them. These undifferentiated cells, called stem cells, have the potential to produce any kind of cells in the body and have the capacity for self-renewal.Stem cell research has proven autologous adipose stem cell therapy from a patients own harvested stem cells to be more effective that other,stem cell therapies such as embryonic stem cell therapy.(Global stem cell network)(n.d.). Live Cell Therapy aims to...
