Cell Migration

Cell 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.

Cell Migration

Cell 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.

Mesenchymal Stem Cells

Mesenchymal Stem Cells

Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their access...

Summary

This summary is machine-generated.

Sphingosine-1-phosphate (S1P) and laminin significantly enhance dental pulp stem cell (DPSC) migration. This finding is crucial for understanding tooth regeneration and developing new regenerative endodontic therapies.

Area of Science:

Stem cell biology
Regenerative medicine
Dental research

Background:

Dental pulp stem cells (DPSCs) play a vital role in tooth repair.
Understanding DPSC behavior is key for advancing regenerative endodontic therapies.
Tooth regeneration after injury requires knowledge of DPSC signaling.

Purpose of the Study:

To investigate dental pulp stem cell (DPSC) migration.
To determine the effect of chemotactants and extracellular matrix proteins (EMPs) on DPSC migration.
To gather DPSC signaling information for tooth regeneration and endodontic therapies.

Main Methods:

DPSCs were cultured and subjected to transwell migration assays.
Tested chemotactants included sphingosine-1-phosphate (S1P), FGF, EGF, and TGF-β1.
Tested EMPs included collagen-I, collagen-IV, laminin, and fibronectin; data analyzed using ANOVA.

Main Results:

Sphingosine-1-phosphate (S1P) significantly increased DPSC migration compared to other tested chemotactants (P < .05).
Laminin significantly increased DPSC migration compared to other tested EMPs (P < .05).

Conclusions:

Extracellular matrix proteins (EMPs), especially laminin, and chemotactants, particularly S1P and TGF-β1, are key promoters of DPSC migration.
The interplay of EMPs, lipids, serum, and chemotactants suggests highly regulated DPSC migration.
Specific chemotactants and EMPs may mediate pulp-dentin regeneration, offering potential for regenerative endodontic therapy.
