Stem cells

During my life I was interested in micro world, I liked to learn about cell, virus, etc. and I wanted a microscope, when I started High school I interested more in cell biology and immune system, Between everything I learned there was something that caught my attention and this was the Stem cells.

Stem cells are a very special type of cells, because have the capacity to transform in any specialized cell of organism, exist various types of stem cells how:

Totipotent stem cells: can differentiate into embryonic and extraembryonic cell types. Such cells can construct a complete, viable organism. These cells are produced from the fusion of an egg and sperm cell.

Dolly sheep

Pluripotent stem cells: are the descendants of totipotent cells and can differentiate into nearly all cells, i.e., cells derived from any of the three germ layers (Endoderm, Mesoderm, and Ectoderm).

Multipotent stem cells: can differentiate into a number of cell types, but only those of a closely related family of cells.

The use of stem cells is very diverse, it is used in research (mainly), cosmetics and as cancer treatment, for these reasons stem cells are very good for Humans. In my career stem cells are used for research.but not everything is good around stem cells, work with stem cells is very difficult because stem cells are difficult to control, may react badly with the patient's immune system and some people may be against and not support the research.



Stem cells have not been out of the controversy, much groups pro-life are against, and during much years the research with stem cells was very controversial, especially during the years of life of Dolly Sheep because this sheep was a first clone of the world born thanks to stem cells, but today the research and use of Stem cells are more common and not so controversial.
