Summary
This summary is machine-generated.Skin pericytes (PCs) demonstrate robust tube-forming ability and attract endothelial cells, suggesting a key role in promoting wound healing by recruiting these cells.
Area Of Science
- Vascular Biology
- Wound Healing Research
- Cell Biology
Background
- Pericytes (PCs) are integral vascular components involved in wound repair processes.
- The specific roles of PCs in wound healing and angiogenesis require further elucidation.
Purpose Of The Study
- To investigate the tube-forming capacity and chemotactic behavior of skin pericytes (PCs).
- To explore the contribution of PCs and endothelial cells to the wound repair process in a rat model.
Main Methods
- Isolation and characterization of skin PCs and human dermal microvascular endothelial cells (HDMECs).
- Assessment of tube formation and chemotaxis using in vitro assays (2D and 3D cultures, transwell assays).
- Evaluation of PC and endothelial cell roles in a rat skin wound model.
Main Results
- Skin PCs possess a distinct morphology and antigen profile (NG2+, PDGFR-β+, α-SMA+, CD31-).
- PCs exhibit significant tube-forming capability, enhanced by hypoxia and starvation, and outperform HDMECs in matrigel.
- PCs recruit HDMECs in vitro and in vivo, with an increasing PC-to-endothelial cell ratio observed post-injury.
Conclusions
- Skin PCs possess potent tube-forming and endothelial cell-attracting properties.
- PCs likely enhance wound repair by recruiting endothelial cells, highlighting their therapeutic potential.

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.
General Mechanism
Generally, cellular migration begins when a cell, such as a fibroblast, responds to an...
Cells migrating in response to external stimuli form lamellipodia, which are thin membrane protrusions supported by a mesh of linked, branched, or unbranched actin filaments. These actin filaments interact with myosin motor proteins, creating the dynamic actomyosin complex within the cytoskeleton. Contractility, or the ability to generate contractile stress, is inherent to the actomyosin complex. It helps cells detect the stiffness of the surrounding ECM and exert contractile force for...
Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon...
The protrusion of the cell surface is an initial step for several cellular processes, including cell migration, phagocytosis, and neurite outgrowth. These membrane protrusions are a result of cytoskeletal rearrangement. The most widely observed cell protrusions include lamellipodia, pseudopodia, filopodia, microvilli, invadopodia, and podosomes. These protrusions can be of two types — static or dynamic.
The microvilli, an example of stable protrusions, are finger-like projections...
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....
