Stem Cells

Stem cells are highly likely to develop into various types of cells in the body. They act as a body repair system. There are mainly two types of stem cells. Embryonic stem cells and adult stem cells.

They may become specialized cells like muscle cells, blood cells and brain cells.

Doctors and scientists are excited about stem cells. Because they can help many different disciplines of health and medicine. Researching stem cells may be helpful in explaining the occurrence of serious diseases such as birth defects and cancer. One day, stem cells can be used to create cells and tissues to treat many diseases. Examples include Parkinson's disease, Alzheimer's disease, spinal cord injury, heart disease, diabetes and arthritis.

There are three types of stem cells. Embryonic stem cells, adult stem cells, artificial pluripotent stem cells (iPS). The most famous type of stem cells are embryonic stem cells. This is due to the extensive coverage of such stem cells by the media and for many judicial laws developed based on their use. They are also popular among researchers because they are the most flexible type of stem cells. Unlike more mature counterparts, they have the ability to regenerate all kinds of cells. Embryonic stem cells are found in two areas: umbilical cord and embryo. Embryonic stem cells are found in the blood taken from the umbilical cord immediately after birth. It contains hematopoietic stem cells that can be used to produce erythrocytes; among other things. There are also mesenchymal stem cells that can be used to grow muscle and bones. Hematopoietic cells are used for the treatment of blood related diseases such as autoimmune diseases and leukemia

The basis of stem cell biology starts with the definition of stem cells. Broadly speaking, stem cells are two important functioning cells: 1) self replication and 2) differentiation, or conversion to other cells. Self-regeneration means that the cell divides (mitotically) and proliferates, or the number increases. Differentiation is the process by which stem cells are converted to another more specialized cell. An example of this is hematopoietic stem cells found in bone marrow, or blood stem cells. They divide to increase its number (self replication) and differentiate into leukocytes to obtain an immune response (author's warning: the technical line is due to the ancestral group) then enter the terminal differentiated cell)
