What are stem cells?

stem cells are special cells in multicellular organisms that are able to distinguish into a wide range of other cells as needed. In other words, the cells themselves are not specialized, such as blood cells, nerve cells, etc., but they can create specialized cells to form an embryo or repair damage to the adult organism. This feature has proposed that they could be very useful in medical treatment and many nations have determined stem cell financing to explore the possibility of research and development. When divided and multiply, they are distinguished to produce organs, muscles, bones, etc. until a complete embryo is formed. Adults also have stem cells, although their exact origin is not fully understood. These adult cells trigger in response to serious damage to replace damaged tissues.

There are three types of stem cells. Embryonic stem cells are taken from EMPRYO. The umbilical blood stem cells come from the umbilical cord that is rich in these cells because it is the soilfetal waters. Adult stem cells are also known as somatic stem cells and are located in many places around the adult body. The exact science and distribution of adult cells is still the theme of intensive research.

In order to be considered as stem cells, the cell must have two properties. The first is that they must not specialize in a specific event, but should be able to generate specialized cells. In addition, they can be replicated many times with errors, which is a process known as proliferation. Research is aimed at exploring this unique feature and scientists hope that one day it will be able to use it and stimulate cells to grow organs for people who need them, for example.

stem cell research is controversial in some parts of the world. Embryonic stem cells could only be harvested by the destruction of the embryo until 2006, when scientists began to prove that the lines can be created without this victim. Due to tOmu that some people are uncomfortable with the idea of ​​killing embryos, this problem raised great concerns among many communities. Other critics are afraid that stem cell research can get lost in the cloning empire and many communities against the cloning of human beings for a number of reasons. Most governments have focused on creating clear and understandable legal regulations on stem cell research in the hope of using their huge potential without causing controversy.
