What are organotypic raft cultures?
Organotypic raft cultures are three-dimensional cell cultures that mimic the architecture and function of epithelial tissues.
How long does the culture process take?
The culture process typically takes 10 to 14 days to maintain at an air-liquid interface.
What types of cells can be used in this method?
Primary keratinocytes, established epithelial cell lines, and biopsy tissues can be used.
What analyses can be performed on the harvested rafts?
Histological and immunohistochemical analyses can be performed to evaluate epithelial differentiation.
Why is this method important for virology?
It allows researchers to study virus:host interactions in a setting that closely resembles in vivo conditions.
Can this method be applied to diseased tissues?
Yes, it can be applied to normal or diseased biopsy tissues to study differences in epithelial behavior.
