About Stem Cells

What are stem cells?

Stem cells are biological cells that, after receiving the right stimuli, have the ability to divide and differentiate into diverse specialized cell types inside the human body (liver, skin, red blood cells, etc.) and can self-renew to produce more stem cells.


Stem cells origin and sources

What are the sources of adult stem cells?

Mainly, and in the case of therapeutic applications, stem cells can be collected from different blood and tissue sources such as peripheral blood, bone marrow, the umbilical cord, fat, etc. These sources provide an important supply of mesenchymal stem cells, hematopoietic stem cells, and endothelial and epithelial cells, which can be used for a wide variety of applications according to the specific protocol of induction, proliferation and orientation.

There are two types of stem cells: adult stem cells and embryonic stem cells.

– Adult stem cells are found in various mature tissues in our bodies and can be extracted from a variety of sources, such as bone marrow, peripheral blood, adipose tissue (fat) and umbilical cord blood (during baby’s delivery). They can self renew and give rise to other cell types from their tissue of origins, thereby reloading adult tissues.

– Embryonic stem cells are derived from an inner cell mass of blastocysts, and can give rise to every cell type in every organ of the body. However, extracting embryonic stem cells requires the destruction of human embryos, making it a controversial process and ethically unacceptable.
