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:

1. Multiplication

Stem cells can multiply repeatedly for prolonged periods and thus, can be preserved in the laboratory.

2. Undifferentiated

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

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.
