Difference Between Hypertrophy and Hyperplasia
The differences between hypertrophy and hyperplasia are as follows:
Characteristics |
Hypertrophy | Hyperplasia |
Definition | The increase in the cell size without an increase in cell number. | Increase in cell number resulting in tissue growth. |
Mechanism | Existing cells enlarge through protein synthesis. | New cells are formed through cell division. |
Trigger | Increased workload or stimulation. | Hormonal factors or tissue damage. |
Tissue Size | Enlargement of existing tissue. | The overall growth of tissue. |
Cellular Changes | Increase in cell size. | Increase in cell number. |
Examples | Muscle hypertrophy due to exercise. | Uterine hyperplasia during pregnancy. |
Organ Adaptation | Allows tissues to generate greater force. | Accommodates the growing fetus. |
Occurrence |
Common in tissues capable of regeneration |
Often occurs in response to injury or tissue growth |
Developmental Biology | Organ growth during development. | Tissue growth in embryogenesis. |
Difference Between Hypertrophy And Hyperplasia
The difference between hypertrophy and hyperplasia lies in their respective mechanisms of tissue growth. Hypertrophy involves an increase in the size of existing cells, while hyperplasia includes an increase in the number of cells through cell division. While both hypertrophy and hyperplasia result in tissue growth, however, they are different in their mechanisms.
In this article, we will cover the major differences between hypertrophy and hyperplasia and study them in brief.
