Summary
Cell-cell adhesion patterns can guide cell behavior, challenging previous assumptions. Combining cell-matrix and cell-cell cues enhances stem cell differentiation, revealing complex adhesion interactions.
Area of Science:
- Biomaterials Science
- Cell Biology
- Tissue Engineering
Background:
- Contact guidance typically studied via cell-matrix interactions.
- The role of cell-cell adhesion in contact guidance remains largely unexplored.
- Understanding these interactions is crucial for biomaterial design.
Purpose of the Study:
- To investigate if cell-cell adhesion can induce contact guidance.
- To explore the guidance effects of combined cell-cell and cell-matrix adhesion patterns.
- To assess the impact on human mesenchymal stem cell (hMSC) differentiation.
Main Methods:
- Engineered microstrip patterns with cell-cell adhesion ligands.
- Created patterns with segregated cell-cell and cell-matrix ligands.
- Utilized these platforms to guide hMSC spreading, adhesion, and differentiation.
Main Results:
- Micropatterns of cell-cell adhesion ligands were found to induce contact guidance.
- Alternating cell-matrix and cell-cell strips also induced contact guidance.
- Combined adhesion patterns enhanced hMSC osteogenic differentiation compared to monofunctional patterns.
Conclusions:
- Cell-cell adhesion is a novel driver of contact guidance.
- Biochemical differences in adhesion potencies influence guidance.
- Synergistic effects of combined adhesions promote stem cell differentiation, highlighting crosstalk.

01:19Cell Migration
6.2K
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.

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.

01:19Mesenchymal Stem Cells
5.4K
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...

8.8K
Cell adhesion molecules (CAMs) are pivotal to multicellularity and the coordinated functioning of tissues and organ systems. They enable physical interactions between cells and provide mechanical strength to tissues. They also function as receptors for signal transmission across the plasma membrane. The CAMs are broadly classified into four families - integrins, cadherins, selectins, and immunoglobulin-like CAMs (IgCAMs).

01:19Cadherins in Tissue Organization
3.8K
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

01:24Overview of Cell-Matrix Interactions
8.7K
The extracellular matrix or ECM holds cells together to form a tissue and allows the cells within the tissue to communicate. ECM comprises proteins such as fibronectin, collagen, laminin, etc. The most abundant protein in this space is collagen. Collagen fibers are interwoven with carbohydrate-containing protein molecules called proteoglycans. ECM allows cell migration and provides a structural scaffold at cell adhesion that anchors the cell when the extracellular matrix proteins interact with...
