Cell Migration, Cell Invasion & Wound Healing Explained

Cell migration is an extremely complex phenomenon. A motile single cell, or multicell aggregate, that penetrates through the extracellular matrix of neighboring tissues can be described as invasive. Cells grouped into coherent sheets, strands, or tubes may undergo a form of collective cell migration governed by tight intercellular connections. The former mechanism is characteristic of metastatic growth, while the latter is associated with wound healing. How can seemingly similar cellular mechanisms result in such dramatically different outcomes?

Principles of Cell Migration

Platypus Technologies is a fast-growing provider of cell migration assays for precise and reproducible experimentation, from academia to the pharmaceutical sector. Our core competency revolves around the cell exclusion zone technology, an innovative, high-throughput cellular assay with real-time monitoring capabilities, and negligible margins of error. This represents a significant step forward for researchers in various clinical fields.

Cell Migration Assay Applications: Pharma Industry

Dynamic cellular migration is of interest to biochemists in various areas of research and development (R&D). This process refers to the movement of individual cells or cellular clusters from one location to another, typically in response to some chemical or mechanical signal. Pharmaceutical companies have been particularly invested in studying cell migration and invasion as these processes underlie an extremely wide range of pathological phenomena – thus offering significant promise for generating valuable pharmacological interventions.

Cell Migration Assay Applications: Research

Understanding cellular invasion and migration is important for studying a wide range of biological processes. By observing the directed rate of movement of cells in response to chemical or mechanical signals, researchers can investigate processes as varied as metastasis and wound healing. Historically, this has proven difficult due to a lack of efficient and reproducible methods for quantitatively assessing cell migration.

What is a Cell Migration Assay?

Cellular migration refers to the movement of cells from one location to another, usually in response to some chemical or mechanical signal. It is fundamental to an extremely wide range of organic processes, from the developmental (i.e. embryogenesis) to ongoing biological maintenance (i.e. tissue repair). Using a cell migration assay, it is possible to measure the net migration and rate of migration for cellular populations in vitro and thus gain an understanding of various bioorganic mechanisms.
