The Significance of Nuclear Deformation for Cancer Cell Transmigration
نویسندگان
چکیده
In this paper, we present a microfluidic platform for the study of cancer cell transmigration and anti-cancer drug screening. The device consists of an array of microchannels with dimensions close to the capillaries on the cellular barriers, while a thin glass coverslip is used as the substrate to enable high resolution imaging of cell dynamics during cancer cell transmigration. We have investigated the transmigration of highly metastatic human breast cancer cells, MDA-MB-231, after their cell nucleus are fluorescently labeled. The results show that 1) the cell nucleus deformed drastically during the transmigration process, and 2) an anti-cancer drug targeting the cell nucleus significantly inhibited transmigration.

A Biomechanical Approach for the Study of Deformation of Red Cells in Narrow Capillaries
This model focuses on the behavior of capillary-tissue fluid exchange system when the diameter of the capillary is less than that of red cell. In vivo and in vitro observations indicate that the width of the gap between the red cell and the vessel wall is generally small compared to the radius of the capillary for a single file flow of red cell in narrow vessel, particularly if the vessel diame...

Objective(s): Small cell lung cancer (SCLC) is an aggressive neuroendocrine carcinoma, which accounts for 10-15% of pulmonary cancers and exhibits early metastatic spread. This study aimed to determine the added value of 18F-FDG PET/CT imaging in tumor, node, and metastasis (TNM) staging of SCLC, compared to the conventional computed tomography (CT) scan and its potential role as a prognosticat...

Background: Breast cancer is known as the most widely recognized dangerous tumors; therefore, the most common reason for mortality among all instances of harmful neoplastic illness in females. This is because the lack of specific signs and symptoms at the early stage and at the aggressive nature. Currently, breast cancer treatment such as chemotherapy, surgery and radiotherapy has not been effe...
