Cell migration is a core in-vitro readout in repair-pathway research: scratch-wound and transwell assays measure how far or how fast cultured cells move, and they are used to compare reference compounds such as BPC-157 and TB-500. This guide explains the readouts.
Why migration is measured
Tissue-repair processes in cell models often involve cells moving to close a gap. Migration assays quantify that movement, giving a defined endpoint for comparing compounds under controlled conditions.
The scratch-wound assay
A confluent cell monolayer is scratched to create a cell-free gap, then imaged over time. The rate at which the gap narrows is the migration readout. It is simple and widely used.
The transwell (Boyden chamber) assay
Cells are placed on a porous membrane and the number that move through toward the other side is counted. This measures directed migration and complements the scratch assay.
Interpreting the data
Because conditions, cell types and timing vary between labs, migration results are compared within a single experiment against proper controls rather than across studies.
