Use and Design. As an industry leader and essential tool in the lab for over 25 years, Transwell permeable supports are backed by extensive citations, protocols, and scientific support—all to help create a cell culture that more closely mimics an in vivo environment. Permeable supports enable life science research and discovery for the study of both anchorage-dependent and independent cell lines. Permeable supports come ready to use, pre-packaged in standard multiple well plates. Individual inserts are also available.

As such, methodologies to assess cell migratory and invasive capacities are necessary to elucidate normal cell processes and underlying mechanisms of disease. Here, we describe commonly used transwell in vitro methods for the study of cell migration and invasion. The transwell migration assay involves the chemotaxis of cells through a porous membrane after the establishment of a chemoattractant gradient using two medium-filled compartments. The transwell invasion assay involves the addition of an extracellular matrix on top of the porous membrane which only permits chemotaxis of cells which possess invasive properties such as tumor cells. Migration of cells, such as leukocytes, stem cells, fibroblasts, and tumor cells are involved in a variety of physiological and pathophysiological processes [ 1 — 10 ]. As such, cellular migration and invasion assays have been widely employed and made a significant impact in the fields of biology and biomedicine [ 1 , 11 , 5 , 7 , 12 ]. Numerous assays have been developed to evaluate spontaneous migration or chemotactic response toward a chemoattractant such as chemokines, bioactive lipids, or growth factors [ 13 — 21 , 4 ]. Here, we outline the widely utilized transwell migration and invasion assays which involve two medium-filled chambers that are divided by a porous membrane [ 13 — 15 , 17 , 18 ].

Chronic inflammation and fibrosis are characteristics of silicosis, and the inflammatory mediators involved in silicosis have not been fully elucidated. Recently, macrophage-derived exosomes have been reported to be inflammatory modulators, but their role in silicosis has not been explored. The purpose of the present study was to investigate the role of macrophage-derived exosomal high mobility group box 3 HMGB3 in silica-induced pulmonary inflammation. HMGB3 expression was increased in exosomes derived from silica-exposed macrophages. Silicosis is an irreversible and fatal lung disease caused by long-term inhalation of silica SiO 2 dust and is characterized by chronic inflammation and fibrosis [ 1 ]. According to a document from the National Health Commission of China, there were 11, new cases of occupational pneumoconiosis in [ 2 ], and more than , pneumoconiosis patients are currently surviving. However, there are limited clinical treatments available for silicosis.
