Differences Between Interstitial Growth and Appositional Growth
The difference between interstitial growth and appositional growth in tabular form is given below:
Basis of Comparison |
Interstitial Growth |
Appositional Growth |
| Definition | The growth occurs through the addition of new cells within the existing tissue. | The growth involves the addition of new cells to the surface of the tissue. |
| Tissues Involved | Occurs in tissues that have the capacity to divide, such as cartilage and bone tissue. | Occurs in tissues that do not have the capacity to divide, such as the outer layer of bone tissue and the skin. |
| Mechanism | Involves cell division (mitosis) of the existing cells in the tissue. | Involves the differentiation of stem cells present in the tissue. |
| Increase in Size | Results in an increase in tissue size by the addition of new cells. | Results in an increase in tissue size by the addition of new tissue layers. |
| Occurrence | Occurs throughout life and is essential for tissue maintenance. | Occurs during growth and is essential for tissue development. |
Difference Between Interstitial and Appositional Growth
The major difference between interstitial and appositional growth lies in the location and mechanism of growth. Interstitial growth occurs within tissues through cell division and enlargement, while appositional growth involves the addition of layers onto the surface.
