Organ-on-a-chip a biochip has been created by researchers at cellasys. Researchers are working towards building a multi-channel 3D microfluidic cell culture system that compartmentalizes microenvironments in which 3D cellular aggregates are cultured to mimic multiple organs in the body. Most organ-on-a-chip models today only culture one cell type, so even though they may be valid models for studying whole organ functions, the systemic effect of a drug on the human body is not verified. In particular, an integrated cell culture analog (µCCA) was developed and included lung cells, drug-metabolizing liver and fat cells. The cells were linked in a 2D fluidic
Adjective Adjective In linguistics, an adjective (abbreviated ) is a describing word, the main syntactic role of which is to qualify a noun or noun phrase, giving more information about the object signified. Adjectives are one of the English parts of speech, although they were historically classed together with the nouns.
