Summary of "Bioprinting for Human Respiratory and Gastrointestinal In Vitro Models."

Increasing ethical and biological concerns require a paradigm shift toward animal-free testing strategies for drug testing and hazard assessments. To this end, the application of bioprinting technology in the field of biomedicine is driving a rapid progress in tissue engineering. In particular, standardized and reproducible in vitro models produced by three-dimensional (3D) bioprinting technique represent a possible alternative to animal models, enabling in vitro studies relevant to in vivo conditions. The innovative approach of 3D bioprinting allows a spatially controlled deposition of cells and biomaterial in a layer-by-layer fashion providing a platform for engineering reproducible models. However, despite the promising and revolutionizing character of 3D bioprinting technology, standardized protocols providing detailed instructions are lacking. Here, we provide a protocol for the automatized printing of simple alveolar, bronchial, and intestine epithelial cell layers as the basis for more complex respiratory and gastrointestinal tissue models. Such systems will be useful for high-throughput toxicity screening and drug efficacy evaluation.

Medical and Biotech [MESH] Definitions

Naturally occurring or experimentally induced animal diseases with pathological processes sufficiently similar to those of human diseases. They are used as study models for human diseases.

A genus of the family CORONAVIRIDAE which causes respiratory or gastrointestinal disease in a variety of mostly mammals. Human betacoronaviruses include HUMAN ENTERIC CORONAVIRUS; HUMAN CORONAVIRUS OC43; MERS VIRUS; and SARS VIRUS. Members have either core transcription regulatory sequences of 5’-CUAAAC-3’ or 5’-CUAAAC-3’ and mostly have no ORF downstream to the N protein gene.

A genus of the family CORONAVIRIDAE which causes respiratory or gastrointestinal disease in a variety of mammals. Human alphacoronaviruses include Human coronavirus 229E and NL63. All members share the identical core transcription regulatory sequences of 5’-CUAAAC-3’ and most have 1 to 2 ORFs downstream to the N protein gene.

Species of the genus MASTADENOVIRUS, causing a wide range of diseases in humans. Infections are mostly asymptomatic, but can be associated with diseases of the respiratory, ocular, and gastrointestinal systems. Serotypes (named with arabic numbers) have been grouped into species designated Human adenovirus A-F.

The transfer of mammalian embryos from an in vivo or in vitro environment to a suitable host to improve pregnancy or gestational outcome in human or animal. In human fertility treatment programs, preimplantation embryos ranging from the 4-cell stage to the blastocyst stage are transferred to the uterine cavity between 3-5 days after FERTILIZATION IN VITRO.
