Morphogenesis of Olfactory Organ of Bushymouth Catfish (Teleostei: Loricariidae) before Switching to Exogenous Feeding.

Olfaction plays an important role in a fish's life. Its value may differ at different developmental stages, depending on the feeding style of the species. The goal of the present study was to investigate the olfactory organ of a species that feeds mainly on algae- the bushymouth catfish, at developmental stages from olfactory placode to the definitive olfactory chamber.

Options for modeling the respiratory system: inserts, scaffolds and microfluidic chips.

The human respiratory system is continuously exposed to varying levels of hazardous substances ranging from environmental toxins to purposely administered drugs. If the noxious effects exceed the inherent regenerative capacity of the respiratory system, injured tissue undergoes complex remodeling that can significantly affect lung function and lead to various diseases. Advanced near-to-native in vitro lung models are required to understand the mechanisms involved in pulmonary damage and repair and to reliably test the toxicity of compounds to lung tissue.
