The world of science is developing very rapidly. This can be explained by the desire of people to know everything, e.g. the origins of life, the structure of human’s organism, the secrets of universe etc. The one of a set of branches in science is regenerative medicine, which includes stem cells research. Generally, stem cells are unique cells in the human’s body, which have an ability to renew themselves and become specialized into liver cells, kidney cells or spinal cord cells from unspecialized type of cells. There are several advantages and disadvantages of using stem cells in treatment the most common diseases of the world. The subject of this research project is to evaluate the benefits and risks of using stem cells in curing global diseases. It merits study, because stem cells are the constituent part of human organism and their abilities must be explored, in order to use them in therapies for diseases such as Alzheimer’s, Parkinson’s, diabetes mellitus, spinal cord injuries and cardiac disorders. It is significant to know possible risks of using stem cells, as well as their benefits. 2. The unique properties of stem cells and the ways of reception. Basically, stem cells are unspecialized cells in the human organism, which have a significant ability to renew themselves and become specialized with new functions. They have distinguishing properties to develop into different types of cells, such as brain cells, nerve or liver cells etc. The stem cells repair dead cells; moreover they can divide without any limitations. Generally, there are four sources of stem cells: stem cells from embryo; stem cells from fetus; stem cells from adult human; stem cells from umbilical cord. Saxena (2009) emphasizes, the stem cells are divided in two categories of their origination: adult and embryo. Embryonic stem cells derived from 5-7 days old fertilized eggs, which are called blastocyst. Specifically, the stem cells are taken from the balstocyst’s cavity, inner cell mass. The most important feature of embryonic stem cells, they are totipotent. This means they can differentiate into every type of cells, whereas human adult stem cells can be differentiated only into the cells, from where they were originated. Another category is human adult stem cells. These stem cells are undifferentiated cells, which can be found among differentiated cells in different organs or tissues. They have the similar properties as embryonic stem cells, but with limitations. Adult stem cells repair the organs and tissues, where they were found (Polak &ump; Bishop 2006). However, the conducting research on embryonic stem cells has controversial debate in the whole world. There are a lot of ethical issues connected with embryonic stem cells. There are most common diseases, which are the main causes of death in the whole world, such as diabetes mellitus; cardiac disorders (ischemic disease); neural diseases (Parkinson’s, Alzheimer’s, spinal cord injuries) . The next paragraphs would describe and evaluate the risks and the benefits of using stem cells in curing these disorders. 3. The application of stem cells in curing the worldwide diseases. i.
