Abstract:
Microfluidic devices provide convenient assays tools for testing cell cultures in three-dimensional (3D) formats. These devices have significant potential for establishing assays that are better at predicting drug toxicity and efficacy effects compared to assays in conventional two-dimensional (2D) cultures. Microfluidic cell culture devices consist of perfused cell culture chambers with inlets and outlet for seeding, culturing, sampling, and assaying the cells. This protocol describes how to prepare and seed cells in a microfluidic cell culture device for drug toxicity testing on cells in a 3D structure. The protocol exemplifies the use of a basic microfluidic device with HepG2 hepatoma cells but can be transferred and optimized for other cells and cell types, including iPSC-derived tissue and organ cells.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
