Traditional animal models to quantify the degree of blood vessel formation are being replaced by cell culture assays
that are easier to set up, statistically reliable and can be automated in a drug screening laboratory. These assays rely on the endothelial cells’ ability to form distinct blood-vessel-like tubules in an extracellular matrix where they can subsequently be visualized by fluorescence microscopy. - [Read An Image-Based Assay of Endothelial Cell Tube Formation as a Model of Angiogenesis]
Choosing a cell viability or cytotoxicity assay from among the many different options available can be a challenging task. Includes information on: Establishing an In Vitro Model System; Choosing an Endpoint to Measure; Characterizing Assay Responsiveness; Determining Dose and Duration of Exposure; Homogeneous Assays for Multiwell Formats and Automated Screening; Additional Factors to Consider When Choosing a Cell Viability Assay; Cell Viability Assays that Measure ATP Protocol; etc.. - [Read Cell Viability Information For Protocols and Applications]
Protocol describes a method for estimation of mammalian cell number in a defined volume of medium using a hemocytometer. Automated methods using cell-counting devices such as those produced by Coulter are desirable when large numbers of individual samples are to be counted. - [Read Estimation of Cell Number by Hemocytometry Counting Protocol]
