The cortical organoid is an efficient model for studying human brain neurodevelopment and neurological disease. However, its three-dimensional structure limits real-time observation of internal physiological changes. Here, we present a protocol for an air-liquid interface attachment culture for cortical organoids. We describe steps for transplanting cortical organoid slices and generating the air-liquid interface. We then detail calcium imaging on organoid external neural networks and immunohistochemical staining on confocal plates.

Background: The microbiome regulates the respiratory epithelium's immunomodulatory functions. To explore how the microbiome's biodiversity affects microbe-epithelial interactions, we screened 58 phylogenetically diverse microbes for their transcriptomic effect on human primary bronchial air-liquid interface (ALI) cell cultures.
Results: We found distinct species- and strain-level differences in host innate immunity and epithelial barrier response.

Unlabelled: Owing to increased pressure from ethical groups and the public to avoid unnecessary animal testing, the need for new, responsive and biologically relevant in vitro models has surged. Models of the human alveolar epithelium are of particular interest since thorough investigations into air pollution and the effects of inhaled nanoparticles and e-cigarettes are needed. The lung is a crucial organ of interest due to potential exposures to endogenous material during occupational and ambient settings.

Exposure of lung epithelia to aerosols is omnipresent. Chronic exposure to polluted air is a significant factor in the development of pulmonary diseases, which are among the top global causes of death, including COVID-19, chronic obstructive pulmonary disease, lung cancer, and tuberculosis. As efforts to prevent and treat lung diseases increase, the development of pulmonary drug delivery systems has become a major area of interest.

Protein aggregates and particles in biopharmaceuticals can induce adverse immune responses in patients. Thus, suppression of the formation of protein aggregates and particles is important for the successful development of therapeutic proteins. Mechanical stresses, including agitation, are widely recognized as stress factors that generate protein aggregates and particles.

Despite the importance of ocular surface in human physiology and diseases, little is known about ion channel expression, properties and regulation in ocular epithelial cells. Furthermore, human primary epithelial cells have rarely been studied in favor of rat, mouse and especially rabbit animal models. Here, we developed primary human Meibomian gland (hMGEC) and conjunctival (hConEC) epithelial cells.
