Infrared microspectroscopic imaging data of single human prostate cancer cells, on an artificial extracellular matrix (Matrigel) thin-film surface, are presented. The spectral intensity maps, obtained in reflection mode, appear to show that the protein intensity distribution observed at the location of a cell changes dramatically depending on the concentration and/or thickness of the underlying...
Versatile synthetic alternatives to Matrigel for vascular toxicity screening and stem cell expansion
The physiological relevance of Matrigel as a cell-culture substrate and in angiogenesis assays is often called into question. Here, we describe an array-based method for the identification of synthetic hydrogels that promote the formation of robust in vitro vascular networks for the detection of putative vascular disruptors, and that support human embryonic stem cell expansion and pluripotency....
Branching morphogenesis of mouse salivary gland has been studied with organ-culture system. We developed a novel transfilter culture system for analyzing branching morphogenesis of the salivary epithelium. The submandibular salivary epithelium from early 13-day mouse fetus, clotted with Matrigel and separated from the mesenchyme by membrane filter, showed extensive growth and branching morphoge...
BACKGROUND Histone deacetylase (HDAC) inhibitors have anticancer effects. Their effects on expression of cell adhesion molecules might be related to their effects on tumor cell invasion. MATERIALS AND METHODS Murine B16-BL6 cells were treated with the HDAC inhibitors, butyrate or trichostatin A. Melanoma cell invasion of the artificial basement membrane, Matrigel, was examined by Transwell ch...
Prostaglandin E2 (PGE2) and leukotriene B4 (LTB4), at nanomolar to micromolar concentrations, elicited migration of human blood T cells and cultured T lymphoblastoma cells of the Tsup-1 line through a layer of Matrigel basement membrane matrix. The density of Tsup-1 cell high-affinity receptors was low for PGE2 and high for LTB4, resulting in respectively predominant chemokinetic and chemotacti...
Microfluidic devices are becoming mainstream tools to recapitulate in vitro the behavior of cells and tissues. In this study, we use microfluidic devices filled with hydrogels of mixed collagen-Matrigel composition to study the migration of lung cancer cells under different cancer invasion microenvironments. We present the design of the microfluidic device, characterize the hydrogels morphologi...
