Cell Types Involved In Wound Healing L5

Question 1

What are Labile cells

Answer 1

Cells involved in wound healing that are constantly dividing and proliferating throughout life. They are derived from Adult Stem cells

Question 2

Examples of Labile cells

Answer 2

1) Gut epithelium
2) Corneal Epithelium
3) Blood cells

Question 3

Function of corneal stem cells

Answer 3

Corneal stem cells in the limbus constantly differentiate into corneal epithelial cells which migrate over the cornea. Dead cells in the central cornea are squeezed out and removed in the tear film

Question 4

What are stable cells

Answer 4

These cells normally divide at a slow rate. However when stimulated by the right growth factors they can significantly increase their replication rate and divide more rapidly (Hyperplasia)

Question 5

Examples of stable cells

Answer 5

Hepatocytes
Fibroblasts
Vascular Endothelial Cells
Smooth Muscle cells
Osteoblasts

Question 6

What are permanent cells

Answer 6

These cells cannot divide, they cannot go through mitosis. However they may be capable of some cellular repair if necrosis is not initiated.

Question 7

Examples of permanent cells

Answer 7

Neurons (rods, cones, ganglion cells of the retina)

Cardiac Myocytes
