Stem Cells and COPD
Stem Cells are also known as regenerative cells as they have the great ability of regeneration. These are biological cells and found in the various tissues like blood, liver, skeletal muscles, skin, bone marrow and brain. These cells have the capability to discriminate between other specialized cells by the process of cellular differentiation. These cells provide a repair mechanism to the human body by regenerating cells.
Types of Stem Cells
There are different types of stem cells which are formed in different parts of our body. Mainly we have four kinds of stem cells.
Embryonic Stem Cells
These cells have the ability to develop into any kind of body cell except umbilical cord and placenta. These are derived from blastocyst i.e. after the 3-5 days of fertilization. At this stage, embryo consists of around 150 cells. In order to get the desired cell, these cells need specific instructions.
