Abstract

Scientific Progress in medicing, gentics, and biology has led to find out new applications that open wide horizons in treating some chronic diseases. One of these applications is conducting researches on stem cells.

Stem cells are defined as a group of undifferentiated calls that can multiply without losing their ability to be distinguished from all other kinds of cells. The fertilized egg is the typical example of the stem cells ehere it is considered the first embryo cell from which all the body cells come out.

The stem cells are regarded as the stars of the modern biology. It is known as undifferentiated cells that are able to produce all the different cells of the body. It could provide many treatment applications because of its ability to renew the body tissues. So, conducting researches on embryo stem cells is the most promising biological technology that could allow reaching new methods to treat damaged tissues or calls due to sone chronic diseases.

However, conducting shch researcges raises moral and legal problems simultaneously. So scientists divide between agreeing and disagreeing on this area and that is reflected in the national and international legislations.

This study is trying to jdentify the stem cells and to clarify the position of the national and internatiomal legislations on conducting researches on stem cells
