Stem cells are those cells in the body of all multi-cellular organisms, which have the ability of changing into different types of cells. They basically function as a repair system, and divide endlessly as long as the organism in which they are present is living.
They are formed in a blank state which makes it easier for them to transform into other tissues, bones and nerve cells as required.
When each stem cell divides to produce a daughter cell, the new cell has the option of either remaining a stem cell or changing into a more specialized one such as a muscle or red blood cell.
These cells are unique as compared to the other cells in the body as they can develop into any other type of cell that is required by the organism. The adult cells that are present in the body are known as being able to heal and repair any part if injured.
The type of diseases that cells are known to be able to cure are degenerative genetic disorders that include Parkinson’s disease, Alzheimer’s disease, diabetes, heart disease and multiple sclerosis. Most of these diseases are genetic in nature, thus, you will find these present in some family members. They affect a person’s movement, action, balance, heart, and speech. At times, drinking alcohol and presence of other illnesses can make these genetic disorders manifest earlier than is normal.
The main reason why they have the capability of curing and treating various diseases and conditions is that it can turn into any tissue. For example, in the case of a person who is suffering from Alzheimer’s disease, stem cells would reach the brain and turn into healthy brain cells, thus curing the condition to a great extent.
Moreover, stem cells have been known as being quite successful in treating spinal cord injuries. Embryotic stem cells are known to have the highest potential to be extremely effective in treating diseases. However, to produce such cells, one has to destruct a human embryo, which is considered highly unethical and undesirable by most people.
