Introduction to Stem Cell
Stem Cells are powerful and unique cells which have, over the last several decades, become targets for exploitation for their therapeutic benefits in several potentially serious and, sometimes, potentially fatal diseases. Their uniqueness stems from the following remarkable properties:
Stem cells can multiply repeatedly for prolonged periods and thus, can be preserved in the laboratory.
Stem cells are not differentiated and retain the ability to give rise to any tissue.
3. Induced Differentiation
Stem cells, based on the environment provided, can differentiate into the particular tissue/organ that is required.
Role of Stem Cells
Stem cells, by virtue of their properties mentioned above, become key players in the genesis and maintenance of our bodies
1. In Normal Body
Normal development of the organs and systems of the baby
Normal day-to-day repair
2. In Diseased Body
Repair and/or replacement of body part/s after injury
Replacement of specific tissues/organs in particular diseases
Types of Stem Cells
With advancing endeavors and successes in research, the knowledge about stem cells increased in leaps and bounds.
The sources of stem cells increased as did the knowledge about the differential capabilities of stem cells obtained from these different sources.
Accordingly, it become important to classify the stem cells based on their origins and capabilities.
