Method Comparison for Analyzing Wound Healing Rates

Resource type
Date created
Wound healing scratch assay is a frequently used method to characterize cell migration, which is an important biological process in the course of development, tissue repair, and immune response for example. The measurement of wound healing rate, however, varies among different studies. Here we summarized these measurements into three types: I) Direct Rate Average; II) Regression Rate Average; and III) Average Distance Regression Rate. Using Chinese Hamster Ovary (CHO) cells as a model, we compared the three types of analyses on quantifying the wound closing rate, and discovered that type I & III measurements are more resistant to outliers and type II analysis is more sensitive to outliers. We hope this study can help researchers to better use this simple yet effective assay.
