Organoids-or pluripotent stem cell-derived in vitro-grown simplified mini organs-have become a tremendously important model to study human organ development and disease. To restrict the noise inherent to the heterogeneous cell mixtures derived from organoid cultures, we developed a new technique of fluorescence-assisted cell sorting (FACS) of virus-infected cerebral organoid cultures. This method still includes the advantage of growing cells in a more natural environment than traditional cell culture, but now renders samples suitable for downstream cell type-specific multi-omics analyses. The protocol starts from stem cell-derived mature brain organoids and includes steps for: preparing the culture for viral infection, production of the viral stocks, FACS sample preparation, and gating and sorting implementation. The protocol has been developed for Zika virus infection, but can be extrapolated to other viruses or fluorescent marker expression as illustrated in an alternate protocol using a single-cycle lentivirus expressing a fluorescent reporter protein. © 2018 by John Wiley & Sons, Inc.

UI MeSH Term Description Entries
D009474 Neurons The basic cellular units of nervous tissue. Each neuron consists of a body, an axon, and dendrites. Their purpose is to receive, conduct, and transmit impulses in the NERVOUS SYSTEM. Nerve Cells,Cell, Nerve,Cells, Nerve,Nerve Cell,Neuron
D009940 Organoids An organization of cells into an organ-like structure. Organoids can be generated in culture, e.g., self-organized three-dimensional tissue structures derived from STEM CELLS (see MICROPHYSIOLOGICAL SYSTEMS). They are also found in certain NEOPLASMS. Organoid
D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon

D002478 Cells, Cultured Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others. Cultured Cells,Cell, Cultured,Cultured Cell
D005434 Flow Cytometry Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.

D000071243 Zika Virus Infection A viral disease transmitted by the bite of AEDES mosquitoes infected with ZIKA VIRUS. Its mild DENGUE-like symptoms include fever, rash, headaches and ARTHRALGIA. The viral infection during pregnancy, in rare cases, is associated with congenital brain and ocular abnormalities, called Congenital Zika Syndrome, including MICROCEPHALY and may also lead to GUILLAIN-BARRE SYNDROME.

D000071244 Zika Virus An arbovirus in the FLAVIVIRUS genus of the family FLAVIVIRIDAE. Originally isolated in the Zika Forest of UGANDA it has been introduced to Asia and the Americas. Virus, Zika,ZikV
