PneumaCult™

Serum- and Bovine Pituitary Extract (BPE)-Free Media for Airway Epithelial Cells

PneumaCult™ is a serum- and bovine pituitary extract (BPE)-free culture system that supports the expansion and differentiation of human airway epithelial cells. Use PneumaCult™-Ex Plus or PneumaCult™-Ex to expand airway epithelial cells in submerged culture. Use PneumaCult™-ALI to achieve extensive mucociliary differentiation at the air-liquid interface (ALI) or in airway organoid culture. Cells expanded and differentiated with the PneumaCult™ system retain key features of the in vivo airway epithelium such as a pseudostratified mucociliated epithelial cell layer consisting of goblet cells, basal cells and motile cilia. ALI cultures provide a physiologically relevant model for studying respiratory biology, infection and disease.

Optimized Medium for ALI Cultures

In vitro models of the human airway using primary nasal, tracheal, or bronchial epithelial cells are instrumental in studying basic and applied aspects of airway biology and disease. Learn how PneumaCult™-ALI is optimized for ALI differentiation to recapitulate the pseudostratified mucociliary phenotype observed in vivo.

Are You Truly Modeling the Human Airway?

Obtaining truly differentiated ALI cultures with optimal morphology and functional readouts can be challenging with primary cells. However, they are crucial for enabling physiologically relevant respiratory research. Explore whether or not your airway cultures truly model the human airway.

Why Use PneumaCult™?

  • Primary human airway epithelial cells differentiated with PneumaCult™-ALI closely model the human airway.
  • Defined and BPE-free PneumaCult™ media formulations maximize experimental reproducibility.
  • Simple and optimized protocols make PneumaCult™ media easy to use.

Why Go BPE-Free?

Bovine pituitary extract (BPE) is an undefined component used in several types of serum-free medium. However its presence can lead to experimental variability. Removing BPE reduces the variability and maximizes experimental reproducibility. The PneumaCult™ system has been formulated to be BPE-free while maintaining the highest possible performance of the media. See the results when PneumaCult™-Ex goes head-to-head with a BPE-containing medium.

Why Use PneumaCult™-Ex Plus?

Current feeder-free expansion media for culturing primary human airway epithelial cells can only support a limited number of passages while maintaining robust mucociliary differentiation potential. Unfortunately, this limitation restricts the number of experiments researchers can perform using primary cells. PneumaCult™-Ex Plus is a feeder- and BPE-free culture medium that puts an end to this limitation: researchers can expand cells for a higher number of passages during expansion culture, while maintaining mucociliary differentiation potential during the subsequent ALI culture. Ultimately, PneumaCult™-Ex Plus enables researchers to perform more experiments with a single sample. See the results when PneumaCult™-Ex Plus goes head-to-head with other commercially-available expansion media.

Figure 1. Overview of the PneumaCult™ Culture System

Expansion of human bronchial epithelial cells (HBECs) in submerged culture is performed with PneumaCult™-Ex Plus or PneumaCult™-Ex. During the early “Expansion Phase” of the ALI culture procedure, PneumaCult™-Ex Plus or PneumaCult™-Ex is applied to the apical and basal chambers. Upon reaching confluence, the culture is air-lifted by removing the culture medium from both chambers, and adding PneumaCult™-ALI to the basal chamber only. Differentiation into a pseudostratified mucociliary epithelium is obtained following 21-28 days of incubation and can be maintained for more than one year.
