Chemotaxis
Chemotaxis — The directed movement of cells in response to a chemical stimulus gradient, relevant to wound healing and immune response research.
What Is Chemotaxis?
Chemotaxis is the directed migration of cells along a concentration gradient of a chemical signal (chemokine, growth factor, or peptide). Chemotaxis assays (Boyden chamber/Transwell) measure the ability of peptides to attract or repel immune cells, fibroblasts, or endothelial cells, which is critical for wound healing and immune responses.
Chemotaxis Assays
- Transwell: Cells migrate through 8 µm pores toward peptide in lower chamber. Count migrated cells
- Scratch assay: Monitor cell migration into a wound gap in the presence of peptide
- Peptide chemoattractants: fMLP (bacterial formylated peptide), LL-37, C5a, defensins
Frequently Asked Questions
What is Chemotaxis?
