Nowadays, stem cells are the hottest topic in the medical field. More and more researches are performed to investigate these mystic cells. In order to go deeper into this topic and fully understand it, let’s first take a look at the stem cells themselves, their origins and characteristics which make them so unique and crucial for the medical field.
Stem cells are very complex and complicated, and, that is why, it takes a lot amount of time to get to the bottom of their structure to be aware and understand how they work and which functions they possess. For the recent 50 years, the knowledge about these cells has developed a lot and still continues developing at the current time, too. They take their roots at the beginning of the 20th century when in 1908 Russian histologist, Alexander Maksimov, proposed the hypothesis about existence of the stem cells and coiled the name for them. Later on, in 1963, Canadian Scientists, James E. Till and Ernest A. McCulloch actually demonstrated the existence of self-renewing cells found in the bone marrow of mice. ( Silverstein, 12) It is impossible to say who exactly the founder of the stem cells was. When it comes to such kind of discussion, it is better to say that a lot of scientists put a great effort to contribute and give development of this field in medicine. All these contributions raised exploration in this area that have the most important and beneficial impact on the medicine.
In the first five days the inner cells of the organism will create the entire body, including all of cell types and organs such as the heart, lung, skin, sperm, eggs and other tissues. This is where stem cells come into play to form and take on specialized functions in the body. Stem cells are defined as unspecialized cells that retain the ability to divide throughout life and take the place of specialized cells that get damaged, are lost, or that die. (Ralbovsky).The human body has over 200 different types of cells throughout it
