Request the EpiAirway Data Sheet



EpiAirway is a ready-to-use, 3D mucociliary tissue model consisting of normal, human-derived tracheal/bronchial epithelial cells also available as a co-culture system with normal human stromal fibroblasts (EpiAirwayFT). Cultured at the air-liquid interface (ALI), EpiAirway recapitulates the in vivo phenotypes of barrier, mucociliary responses, infection, toxicity responses and disease. With over 100 technical references available, EpiAirway is amenable to acute or long-term chronic studies across a wide range of highly predictive in vitro applications. 

EpiAirway at 6 weeks in culture. 

EpiAirway exhibits human relevant tissue structure and cellular morphology with high uniformity and reproducibility. Its 3D structure consists of organized Keratin 5+ basal cells, mucus producing goblet cells, functional tight junctions and beating cilia. EpiAirwayFT incorporates human fibroblasts in an extracellular stromal matrix ideal for inflammation and fibrosis research. 



Kit: A standard EpiAirway kit (AIR-100) consists of 24 tissues. (Tissue “kits” contain tissues, a small amount of culture medium, and plasticware; contact MatTek for specific kit contents)


  • 9mm & 22mm individual inserts – tissue culture substrate is chemically modified with a pore size of 0.4 μm
  • 24mm, 12mm & 6.5mm Transwell inserts with a pore size of 0.4 μm
  • 96-well HTS plates – tissue culture substrate is chemically modified with a pore size of 0.4 μm

Culture: Air-liquid interface

Histology: 3-4 cell layers – pseudostratified, mucociliary morphology and tissue structure

Lot numbers: Tissue lots produced each week are assigned a specific lot number. A letter of the alphabet is appended to the end of the lot number to differentiate between individual kits within a given lot of tissues. All tissue kits within a lot are identical in regards to cells, medium, handling, culture conditions, etc.

Shipment: At Room Temperature on medium-supplemented, agarose gels

Shipment day: Every Monday

Delivery: Tuesday morning via FedEx priority service (US). Outside US: Tuesday-Thursday depending on location

Shelf life: Including time in transit, tissues may be stored at 4°C for up to 3 days prior to use. However, extended storage periods are not recommended unless necessary. In addition, the best reproducibility will be obtained if tissues are used consistently on the same day, e.g. Tuesday afternoon or following overnight storage at 4°C (Wednesday morning)

Length of experiments: Tissue cultures can be continued for THREE (3) MONTHS or more with good retention of normal morphology. Tissues must be fed every other day with 5.0 ml of maintenance medium (AIR-100-MM).  Cell culture inserts are placed atop washers (EPI-WSHR) or culture stands (MEL-STND) in 6-well plates to allow us of 5.0 ml.  See technical reference #631.

Alternatives: Phenol red-free, antibiotic-free, anti-fungal-free medium and tissues are available. Agents are removed at least 3 days prior to shipment.

Assay medium: AIR-100-ASY

Maintenance medium: AIR-100-MM


Quality Control and Sterility

Visual inspection: All tissues are visually inspected and if physical imperfections are noted, tissues are rejected for shipment

End-use testing: Transepithelial electrical resistance (TEER) of each EpiAirway lot is measured using an EVOM2 epithelial Volthommeter and Endohm electrode chamber (World Precision Instruments). A minimum TEER of 300 Ohm • cm2 is required for QC release.

Sterility: All media used throughout the production process is checked for sterility. Maintenance medium is incubated without antibiotics for 1 week and checked for sterility. The agarose gel from the 24-well plate used for shipping is also incubated for 1 week and checked for any sign of contamination

Screening for pathogens: All cells are screened and are negative for HIV, hepatitis B and hepatitis C using PCR. However, no known test method can offer complete assurance that the cells are pathogen free. Thus, these products and all human derived products should be handled at BSL-2 levels (biosafety level 2) or higher as recommended in the CDC-NIH manual, “Biosafety in microbiological and biomedical laboratories,” 1998. For further assistance, please contact your site Safety Officer or MatTek technical service

Notification of lot failure: If a tissue lot fails our QC or sterility testing, the customer will be notified and the tissues will be replaced without charge when appropriate. Because our QC and sterility testing is done post-shipment, notification will be made as soon as possible (Under normal circumstances, TEER failures will be notified by Wednesday 5 p.m.; sterility failures will be notified within 8 days of shipment)

The EpiAirway 3D human tissue model is routinely utilized for a range of applications including safety & risk assessment, anti-viral research, inflammation & fibrosis and drug delivery. Simple protocols and the evaluation of early cellular endpoints allow scientists to acquire data in days, not weeks or months.
