Stem cell treatment is claimed as new techniques to heal severe diseases such as cancer, HIV / AIDS, heart disease, and some other diseases. Based on its ability to differentiate stem cells are grouped into several types. What are the types?
The stem cells that can differentiate into all types of cells.Which includes stem cells are totipotent zygote and morula. These cells are an early embryonic cells that have the ability to form different types of cells, including the cells that make up the placenta and umbilical cord. Therefore, stem cells in this group has the ability to form a whole individual.

This stem cells can differentiate into three germ layers (ectoderm, mesoderm, and endoderm) but cannot be extraembryonic tissues such as the placenta and umbilical cord. Cells that are included in pluripotent stem cells are embryonic stem cells (embryonic stem cells)
This stem cells can differentiate into various cell types. For example, stem cells hemopoetik (hemopoetic stem cells) in the bone marrow that have the ability to differentiate into various cell types in the blood such as erythrocytes (red blood cells), leukocytes (white blood cells), and thrombocytes (platelets). However, bone marrow cells do not produce heart cells.
This stem cells have limited reproductive ability and can only differentiate into one cell type. In contrast to the non-stem cells, stem cells still have properties can renew or regenerate themselves (self-regenerate or self-renew). Unipotent stem cells derived from multipotent stem cells in adult tissues and form. Skin cells is one of the most prolific examples of unipotent stem cells.
Stem cells are found in various tissues of the body, then based on the origin of the cells stem cells are grouped into the following:
Embryonic stem cells are stem cells taken from embryos at the blastocyst phase consisting of 50-150 cells (aged 5-7 days after fertilization). At this time the inner cell mass and contain a cluster of embryonic stem cells.
Furthermore, cells isolated from the inner cell mass and cultured in vitro in the laboratory. Embryonic stem cells can be directed into any type of cell found in the adult organism, such as blood cells, muscle cells, liver cells, kidney cells, and other cells.

This cells are obtained from adult cells. Adult stem cells have two characteristics. The first characteristic is the cells can proliferate (rapid cell growth to produce new tissue) for a long period to renew themselves. The second characteristic, the cells can differentiate to produce specialized cells that have the morphological characteristics and special functions.
"Stem cell therapy" is not yet too familiar in some countries, including Indonesia. However, it does not mean we should not know anything about this unique healing technology.
Well, what, friends? Is your information about stem cells has increased? Hopefully this information help you.
