Investigative Ophthalmology & Visual Science
|February 1, 1977
Summary
Actin filament distribution differs between normal and migrating rat corneal epithelial cells. Migrating cells show concentrated basal actin, potentially driving cell movement during wound healing.
Area of Science:
- Cell Biology
- Cytoskeleton Dynamics
- Epithelial Tissue Research
Background:
- Actin filaments form a critical cellular cytoskeleton.
- Understanding actin organization is key to cell motility.
- Corneal epithelial cells play a vital role in wound healing.
Purpose of the Study:
- To investigate the distribution of actin filaments in normal and migrating rat corneal epithelial cells.
- To elucidate the role of actin cytoskeleton in epithelial cell migration during wound repair.
Main Methods:
- In situ labeling of actin filaments using myosin subfragment-one.
- Microscopic analysis of actin distribution in normal and migrating corneal epithelial cells.
Main Results:
- Normal corneal epithelial cells exhibit an apical actin network, supporting microplicae structure.
- Migrating epithelial cells display concentrated basal actin filaments, forming bundles and networks.
- Actin filaments are prominent in the leading edges and cell processes of migrating cells.
Conclusions:
- The apical actin network in normal cells maintains microplicae structure.
- Basally located actin filaments in migrating cells are crucial for cell migration during wound healing.
- Actin dynamics are fundamentally altered during epithelial wound repair.

01:09Cell Migration
Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.
01:10The Role of Actin and Myosin in Non-muscle Cells
Actin and myosin or actomyosin filaments also play a significant role in cells other than those involved in muscle contraction (which occurs within the sarcomere of muscle cells). The mechanism of non-muscle cell contractile bundles was first observed in Dictyostelium and Acanthamoeba. In non-muscle cells, two bundles are commonly found: stress fibers and actomyosin adherence belts. These contractile bundles are smaller and less organized than the ones found in muscle cells. They are held...
01:19Cell Migration
Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.
01:13Actin Polymerization and Cell Motility
Actin is a family of globular proteins that are highly abundant in eukaryotic cells. It makes up approximately 1-5% of total cell protein concentration. Actin monomers polymerize to form a complex network of polarized filaments, the actin cytoskeleton, that plays a crucial role in many cellular processes, including cell motility, division, endocytosis, and metastasis of cancer cells.
Actin cytoskeleton dynamics can produce pushing, pulling, and resistance forces that help the cell to migrate.

01:18Role of Myosin in Cell Migration
Myosins are multimeric motor proteins involved in various cellular processes such as migration, adhesion, and proliferation. Myosin II is the most common type in animal cells, which binds and cross-links actin filaments.
Myosin II is a hexamer comprising two heavy chains with globular heads and coiled-coil tails, two regulatory light chains, and two essential light chains. The ATPase sites on the myosin heads hydrolyze ATP, and the released phosphate generates the force for contraction. It is...

01:32Cytoskeletal Coordination in Cell Migration
A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles correspondingly. These complex events are orchestrated by the dynamic cytoskeletal network comprising actin filaments, intermediate filaments, and microtubules. Cytoskeletal crosstalk — the direct and indirect communication between the different components — is crucial for this coordination. Direct communication involves various linker proteins that...
