Overview

PneumaCult™-Ex Plus Medium is a defined, serum- and BPE-free cell culture medium that supports more expansion of primary human airway epithelial cells at each passage, compared to other commercially-available expansion media. This medium also supports at least two additional passages of cell expansion with better differentiation potential, defined as the ability to form a pseudostratified mucociliary epithelium at the air-liquid interface (ALI) using PneumaCult™-ALI Medium (Catalog #05001).

Together, PneumaCult™-Ex Plus and PneumaCult™-ALI constitute a fully integrated BPE-free culture system for in vitro human airway modeling. This robust and defined system is a valuable tool for basic respiratory research, toxicity studies, and drug development.
Advantages:
• A defined, serum- and BPE-free cell culture medium that delivers consistent performance
• PneumaCult™-Ex Plus Medium supports more cell expansion at each passage compared to other commercially-available expansion media
• When used together with PneumaCult™-ALI Medium, PneumaCult™-Ex Plus Medium supports better ALI differentiation potential even after extended passaging compared to 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 air-liquid interface (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.

Figure 2. HBECs cultured in PneumaCult™-Ex Plus have a faster expansion rate compared to those cultured in PneumaCult™-Ex and Bronchial Epithelial Growth Media

Commercially available, cryopreserved P1 HBECs were seeded into PneumaCult™-Ex Plus, PneumaCult™-Ex, or Bronchial Epithelial Growth Media. Cells cultured in PneumaCult™-Ex Plus have a significantly higher proliferation rate over 9 passages compared to those maintained in either control medium (n=6).

Figure 3. Representative morphology of HBECs

Representative live culture images for P4 HBECs cultured in PneumaCult™-Ex Plus, PneumaCult™-Ex, or Bronchial Epithelial Growth Media. Cells cultured in PneumaCult™-Ex Plus (A) are smaller and more tightly packed than those cultured in PneumaCult™-Ex (B) or Bronchial Epithelial Growth Media (C). All images were taken using a 10X objective.

Figure 4. HBECs cultured in PneumaCult™-Ex Plus maintain widespread expression of the basal cell markers CD49f and CD271

Immunocytochemistry detection of basal cell markers - CD49f (A, B, and C) and CD271 (D, E, and F) - for P4 HBECs cultured in PneumaCult™-Ex Plus (A and D), PneumaCult™-Ex (B and E), and Bronchial Epithelial Growth Media (C and F). All images were taken using a 10X objective.

Figure 5. HBECs cultured in PneumaCult™-Ex Plus have a higher proportion of CD271+CD49f+ cells

P4 HBECs cultured in PneumaCult™-Ex Plus (A), PneumaCult™-Ex (B), and Bronchial Epithelial Growth Media (C) were characterized by flow cytometry to detect expression of the basal cell markers CD49f and CD271. HBECs cultured in PneumaCult™-Ex Plus (A) have a higher proportion of cells coexpressing CD49f and CD271, compared to those cultured in PneumaCult™-Ex (B) and Bronchial Epithelial Growth Media (C).

Figure 6. HBECs cultured in PneumaCult™-Ex Plus differentiate into a pseudostratified mucociliary epithelium at later passages with the use of PneumaCult™-ALI

P4 HBECs were seeded and passaged using PneumaCult™-Ex Plus, PneumaCult™-Ex, or Bronchial Epithelial Growth Media, followed by ALI differentiation at each passage (P5-8) with the use of PneumaCult™-ALI. The ALI cultures at 28 days post air-lift were fixed and stained with antibodies for cilia marker AC-tubulin (red) and the goblet cell marker Muc5AC (green). The nuclei are counterstained with DAPI (blue). All images were taken using a 20X objective.

Amiloride: ENaC inhibitor. IBMX and Forskolin: CFTR activators. Genistein: CFTR potentiator. CFTRinh-172: CFTR inhibitor. UTP: Calciumactivated Chloride channels (CaCCs) activator. All ALI differentiation cultures were performed using PneumaCult™-ALI.
