The cell migration/wounding assay is a commonly used method to study cell migration and other biological processes, such as angiogenesis and tumor metastasis. In this assay, cells are grown to form a confluent monolayer and a mechanical wound is created by scratching with a device. Then the migration rate of the cells towards the denuded area can be monitored by imaging. Our 8-channel mechanical wounder is designed to tackle most of the problems associated with the cell migration assay. Firstly, our wounder can be easily sterilized by autoclaving or with common disinfectants. Secondly, the individual adjustable pins allow even contact with the cell culture plate so that sharp and reproducible wounds can be created. Thirdly, the guiding bars on both sides of the wounder ensure consistent wounding position in each well. The use of disposable plastic pipette tips for wounding can further provide better handling of the wounder as well as to minimize cross-contamination. In conclusion, our cell wounder can provide researchers with a user friendly and reproducible device for performing the cell migration assay using the standard 96-well culture plate.
细胞迁移/划痕实验是一种常用的方法,用于研究细胞迁移以及其他生物学过程,如血管生成和肿瘤转移。在该实验中,细胞生长形成汇合的单层,然后用一种器械刮擦造成机械性损伤。接着,通过成像监测细胞向裸露区域的迁移速率。我们的八通道机械划痕器旨在解决与细胞迁移实验相关的大多数问题。首先,我们的划痕器可通过高压灭菌或使用普通消毒剂轻松消毒。其次,各个可调节的针脚能与细胞培养板均匀接触,从而产生清晰且可重复的划痕。第三,划痕器两侧的导杆确保每个孔中的划痕位置一致。使用一次性塑料移液管吸头进行划痕可进一步便于操作划痕器,并将交叉污染降至最低。总之,我们的细胞划痕器可为研究人员提供一种用户友好且可重复的设备,用于使用标准96孔培养板进行细胞迁移实验。
