Culturing A549 and Small Airway Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
A549 cells (American Type Culture Collection, #CCL-185) were cultured in DMEM supplemented with 10% heat-inactivated fetal bovine serum (FBS). The cells were passaged <20 times. Small airway epithelial cells (American Type Culture Collection, #PCS-301-010) were cultured in small airway epithelial growth media (Lonza #CC-3118) and passaged < 7 times. For studies using cell death inhibitors, deferoxamine mesylate (Selleckchem #S5742), necrosulfonamide (Selleckchem #S8251), and Z-VAD-FMK (Selleckchem #S7023) were dissolved in DMSO, and cells were treated at indicated concentrations

Immortalization of Human Small-Airway Epithelial Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human small-airway epithelial cells (hSAECs) from a cadaveric donor were immortalized using human telomerase/CDK4, as previously described [20 (link),21 (link)]. These non-oncogenic, telomerase-immortalized cells maintain genomic and proteomic signatures representative of primary SAECs over many population doublings [21 (link)] and manifest characteristic cell-state transitions typical of primary hSAECs [20 (link),22 (link),23 (link)]. hSAECs were grown in small-airway epithelial cell growth medium (Lonza, cc-3118) in a humidified atmosphere of 5% CO2. For validation experiments, primary small-airway epithelial cells (pSAECs) were obtained from cadaveric donors (ATCC, PCS-301-010). Cells were grown in airway epithelial cell basal medium (ATCC, PCS-300-030) supplemented with a bronchial epithelial cell growth kit (PCS-300-040).

Airway Basal Stem Cell Differentiation

Tracheal cells were harvested and cultured as previously described (Mou et al., 2016 (link)). Briefly, cells were cultured and expanded in complete SAGM (small airway epithelial cell growth medium; Lonza, CC-3118) containing a TGF-β/BMP4/WNT antagonist cocktail and 5 μM ROCK inhibitor Y-27632 (Selleckbio, S1049). To generate ALI cultures, airway basal stem cells were seeded onto transwell membranes and differentiated using PneumaCult-ALI Medium (StemCell, 05001). Air-liquid cultures were fully differentiated after 14 days as demonstrated by the formation of air-liquid interface and the beating of cilia.

Mouse Lung Epithelial Cell Culture Protocol

Mouse Lung Epithelial (MLE12) cells were obtained from ATCC and grown in HITES media as formulated by ATCC. Tunicamycin (Tun) was purchased from Millipore. STF-083010, KIRA7 and KIRA8 were synthesized in house. Mouse primary AECII cells were isolated as described [42 (link)]. Cells were grown in SAGM media (Lonza CC-3118) on fibronectin coated plates.

Clonal Alveolar Organoid Assay

Check if the same lab product or an alternative is used in the 5 most similar protocols
Clonal alveolar organoid assays were performed as described previously with some modifications from the original protocol17 (link),37 (link),81 (link). In brief, 5 × 103 AT2 cells were isolated as described above and mixed with 5 x104 lung PDGFRα+ isolated cells from adult wild type mice as previously described19 (link) for mouse or MRC5 cells (ATCC CCL-171, tested negative for mycobacterial contamination, at no greater than passage 7) for human cultures. For the first two days of culture, ROCK inhibitor Y27632 (Sigma-Aldrich catalog #Y0503) was added to the media (SAGM; Lonza catalog #CC-3118). After two days of culture, Y276632 was removed and ligand treatments of organoids were performed using the following reagents at the indicated concentrations: ANA-12 0.02μg/mL (Alomone Labs catalog #A-215), recombinant human BDNF 0.05μg/mL (Alomone Labs catalog #B-250) and recombinant murine FGF7 0.01μg/mL (R&D Systems catalog #5028-KG). DMSO was used as a control for the ANA-12 and 2% BSA was used as a control for the BDNF and FGF7. Media was changed every 48 hours, and fresh ligands were included at each media change. After 21 days (or 28 days where indicated) organoids were imaged using an Olympus MVX10 microscope or EVOS FL microscope (Life Technologies).

Airway Basal Stem Cell Differentiation

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cells were cultured and expanded in complete SAGM (small airway epithelial cell growth medium; Lonza, CC-3118) containing TGF-β/BMP4/WNT antagonist cocktails and 5 μM Rock inhibitor Y-27632 (Selleckbio, S1049). To initiate air–liquid interface (ALI) cultures, airway basal stem cells were dissociated from mouse tracheas and seeded onto transwell membranes. After reaching confluence, media was removed from the upper chamber. Mucocilliary differentiation was performed with PneumaCult-ALI Medium (StemCell, 05001). Differentiation of airway basal stem cells on an air–liquid interface was followed by directly visualizing beating cilia in real time after 10–14 days.
Once air-liquid cultures were fully differentiated, as indicated by beating cilia, treatment cultures were supplemented with 25ng/mL of recombinant murine IL-13 (Peprotech-stock diluted in water and used fresh) diluted in PneumaCult-ALI Medium, while control cultures received an equal volume of water for 72 hours. After treatment, whole ALI wells were fixed in 4% PFA, immunostained in whole mount using the same buffers and imaged with a confocal microscope as described above.

Alveolar Organoid Culture Optimization

Check if the same lab product or an alternative is used in the 5 most similar protocols
Alveolar organoids were cultured as described previously29 (link),31 (link), with the following modifications. Briefly, 5 × 103 AT2s sorted from either SPCΔAb1 and Ab1fl/fl mice were co-cultured with 5 × 104 Pdgfrα+ lung fibroblasts sorted from WT C57Bl/6 mice. Cells were suspended in 90μL of a 1:1 mixture of Matrigel:modified SAGM media (CC-3118, Lonza). SAGM media is modified by adding 0.1 μg/mL cholera toxin (C8052, Sigma) and the following SAGM BulletKit components: 10 μg/mL insulin, 5 μg/mL transferrin, 25 ng/mL EGF, 30 μg/mL bovine pituitary extract, 0.01 μM retinoic acid, and 5% FBS. The 1:1 mixture containing cells was placed in a cell culture insert (353095, Corning); after solidification of the matrix at 37 °C, the insert was placed inside a well of 24-well plate containing modified SAGM media. For the first two days of culture, 10 μM ROCK inhibitor Y27632 (Y0503, Sigma) was added to the media. The media was changed every 48 h, and after 21 days organoids were imaged using an EVOS FL Auto using built-in EVOS FL Auto software. Organoid numbers were quantified in Fiji using the Cell Counter plugin.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
