This approach is however demanding, tedious, and time-consuming. These packages have been previously used to manually count cells (selecting and tallying individual cells) and to assess wound closure (tracing the wound perimeter and calculating the percentage of closure). Some of the most popular software packages for this application include the open source imageJ/Fiji® and licensed ones such as Matlab®. The last step is to monitor the migration path of cells in the leading edge of the scratch by tracking it with the aid of time-lapse microscopy (4) and image analysis software. The next step is exposure to the treatment and image acquisition at the beginning and at regular intervals during cell migration as the scratch closes. Methods that are more sophisticated include molds or cell inserts, electric currents, lasers and magnets. The first step is to create manually a “scratch” in a cell monolayer, using pipette tips, razors, cell scrapers, or any object with a sharp tip. Some adherent cell lines used for the assay are endothelial, fibroblast and epithelial.
This straightforward technique relies on adherent cells that could vary depending on the particular cellular processes to study. Additionally, the produced data is relatively easy to analyze with an ample variety of open access software packages. The most remarkable advantages of this assay are the low requirements of specialized equipment or expensive reagents, which makes it adaptable to research groups with limited budgets. This is because this approach provides an environment that mimics that of a wound healing process in vivo. In this context, the in vitro scratch wound healing assay is useful to evaluate the proliferation and migration process when exposing cells to metabolites present in the conditioned media.

Furthermore, it is possible to study the response of free cells and those seeded on scaffolds made of both synthetic polymers and natural extracellular matrices. This technique is suitable to study the paracrine signals (conditioned media) produced by stem or other types of cells under either mechanical or electrical stimuli. Some of these molecules include growth factors, proteins, natural compounds, and small pharmacological principles, among many others.
In this regard, the scratch or migration assay is a widely used tool for in vitro studies of the rates of migration, angiogenesis, movement, proliferation, and healing in response to different novel drug candidates. In order to develop robust therapeutic approaches, it is imperative to study these processes in detail. Some phases that occur during wound healing have also been observed during cancer invasion. Growth factors and matrix signals that determine the function of cells in regeneration processes orchestrate this behavior.

In conclusion, this new imageJ plugin is a robust tool to automatically standardize and facilitate quantification of different in vitro wound parameters with high accuracy compared with other tools and manual identification.Ĭellular behavior regulates wound healing during the phases of proliferation, migration, matrix formation, and contraction.
Additionally, it allows the analysis of images obtained from bright field, phase contrast, and fluorescence microscopes. It can be adapted to analyze both individual images and stacks.

Our plugin is easy to install and can be used with different operating systems. For that reason, we developed an optimized plugin for imageJ to automatically recognize the wound healing size, correct the average wound width by considering its inclination, and quantify other important parameters such as: area, wound area fraction, average wound width, and width deviation of the wound images obtained from a scratch/ wound healing assay. There are open-source programs such as imageJ to analyze images of in vitro scratch wound healing assays, but these tools require manual tuning of various parameters, which is time-consuming and limits image throughput. In vitro scratch wound healing assay, a simple and low-cost technique that works along with other image analysis tools, is one of the most widely used 2D methods to determine the cellular migration and proliferation in processes such as regeneration and disease.
