a tool to automatically create stable and reproducible cell-free gaps for improving the reliability of cell wound healing assay

Tumors are characterized by distinct hallmarks such as selective growth advantages, metabolic rewiring, and immune modulation, all of which intriguingly contribute to enhanced cell migration, a critical malignant behavior of tumor cells. This feature directly affects the distant metastasis of the primary tumor, compromising the long-term survival of patients1,2,3. Selective growth advantages enable cancer cells to outcompete normal cells, while metabolic rewiring supports this rapid proliferation by altering energy pathways. Concurrently, immune modulation allows tumors to evade the body&#39;s defenses. Studies underscore the severity of this issue, showing that lung metastasis, often a result of enhanced cell migration, is a terminal event leading to the death of patients with various cancers4. For instance, breast cancers5, cervical carcinoma4, and osteosarcoma6 account for 20%, 9%, and 30% of such cases, respectively. Therefore, assessing tumor cell migration has become integral to current oncology research, further highlighting the multifaceted nature of tumor progression.
Cell wound healing assay is an easy-to-use method for measuring in vitro cellular migration, often employed in oncological studies7. Most experimenters use pipette tips to create cell wounds manually8. Although such a method could form cell wounds rapidly and conveniently, it still has many limitations that affect reproducibility and accuracy for evaluating cell migration. Firstly, using pipette tips to create scratches manually is highly influenced by the operator&#39;s operating angle, force, and speed, affecting the method&#39;s repeatability8. Secondly, tip-generated cell defects usually have jagged edges rather than straight edges because pipette tips are plastic products with certain elasticity9. Some studies generate wounds by placing prefabricated culture inserts directly into the cell culture plate to restrict the range of cell proliferation10. This approach circumvents the limitation of the tips-based method, such as jagged edges and reproducibility. However, even with biocompatible materials, the long-term coexistence of the embedding with the cells still impacts cell growth11. Moreover, the embedding may also cause cellular epigenetic changes in the marginal zone due to contact restriction12. Also, contact-insert produced from biocompatible materials are expensive and difficult to reuse, limiting their feasibility13. Therefore, a novel, reproducible, and practical tool is needed to easily quantify in vitro cellular migration.
The primary goal of this method is to introduce an innovative tool for quantifying in vitro cellular migration in oncological studies, addressing the limitations of existing techniques and enhancing reproducibility and accuracy in assessing cellular migration.
The rationale behind this technique&#39;s development lies in the critical importance of evaluating tumor cell migration in oncology. Tumors exhibit distinctive hallmarks, including selective growth advantages, metabolic rewiring, and immune modulation, all contributing to enhanced cell migration, a fundamental aspect of cancer malignancy. This method aims to provide a more dependable means of studying cellular migration, contributing to a deeper understanding of tumor behavior.
This method offers substantial advantages over existing techniques. Manual scratch assays can suffer from operator-dependent interference, while culture inserts may impact cell growth and gene expression. In contrast, this method offers improved repeatability, accuracy, and practicality, presenting a cost-effective solution for measuring in vitro cellular migration in oncology research. It addresses a crucial need for a reliable and accessible tool to study cell migration in various cancer types, making it a valuable addition to the field.

一种自动创建稳定且可重现的无细胞间隙的工具，用于提高细胞伤口愈合测定的可靠性

Through the incorporation of interaction experience design and user requirements analysis, we introduce a innovative cell scraper that enhance cellular wound healing assays in terms of reproducibility, dependability, practicality, cellular integrity, and user experiences. We authorized consultative rhinal, keystone, and photocell for product visualizations. This approach that only is in pre-producing the actual product, but also we enhance communications among team members.Additionally, it contributes to reducing the overall year costs. In experimental validations, the cell scraper showed higher survival and proliferation risk than the TIPS group post wound completion confirmed by an EdU assay. This indicates a scraper superiority in creating stable biologically reproducible cell walls compared to the traditional method with minimal impact on cell health.

The reliability of cellular migration measurement in wound healing assays is frequently undermined by the prevalent methodological instability, i.e., ...
