Types of hyperplasia:
1. Physiologic hyperplasia –
Hormonal hyperplasia – eg. Proliferation of glandular epithelial cells of female breast tissue at puberty and lactation
Compensatory hyperplasia – eg. Liver regeneration after partial hepatectomy
2. Pathologic hyperplasia –
Endometrial hyperplasia due to excess of estrogen hormones
Benign prostatic hyperplasia due to excess of androgens
Skin warts due to viral infection
1. Definition of Hypertrophy and Hyperplasia: Hypertrophy: Hypertrophy is an increase in the volume of a given tissue or organ due only to the enlargement of the cells. Hyperplasia: Hyperplasia is an increase in the amount of tissue, resulting from cell proliferation. 2. Genesis of Hypertrophy and HRead more
1. Definition of Hypertrophy and Hyperplasia:
Hypertrophy: Hypertrophy is an increase in the volume of a given tissue or organ due only to the enlargement of the cells.
Hyperplasia: Hyperplasia is an increase in the amount of tissue, resulting from cell proliferation.
2. Genesis of Hypertrophy and Hyperplasia:
Hypertrophy: Hypertrophy is mainly provoked by increased demand.
Hyperplasia: Hyperplasia is mainly provoked by excessive cell stimulation.
3. Process of Hypertrophy and Hyperplasia:
Hypertrophy: Hypertrophy is a result of cell enlargement.
Hyperplasia: Hyperplasia is a result of cell proliferation.
4. Mechanism of Hypertrophy and Hyperplasia:
Hypertrophy: Hypertrophy is a result of increased protein production in the cells.
Hyperplasia: Hyperplasia is a result of the proliferation of mature cells, driven by growth factors.
5. Affected cells of Hypertrophy and Hyperplasia:
See lessHypertrophy: Hypertrophy occurs in permanent cells (non-dividing, such as skeletal muscle, cardiac muscle, etc.).
Hyperplasia: Hyperplasia occurs in labile or stable dividing cells.
