Generation of Organotypic Raft Cultures from Primary Human Keratinocytes
1Department of Microbiology & Immunology, University of North Carolina-Chapel Hill, 2Lineberger Cancer Center, University of North Carolina-Chapel Hill
An in vitro method to mimic in vivo epithelial differentiation is described. Many viruses target epithelial cells as part of their viral life cycle, and this method provides a means of examining virus:host interactions that more closely resembles that which occurs in vivo. This technique can be used with primary keratinocytes, established cell lines, as well as normal or diseased biopsy tissue.
Determination of Lipid Raft Partitioning of Fluorescently-tagged Probes in Living Cells by Fluorescence Correlation Spectroscopy (FCS)

A technique to probe the lipid raft partitioning of fluorescent proteins at the plasma membrane of living cells is described. It takes advantage of the disparity in diffusion times of proteins located inside or outside of lipid rafts. Acquisition can be performed dynamically in control conditions or after drug addition.
The Organotypic Hippocampal Slice Culture Model for Examining Neuronal Injury
Department of Neurology and Neurological Sciences, Stanford University School of Medicine
The organoptypic hippocampal slice culture model is an in vitro model used to examine neuronal injury in a variety of paradigms. In this article, we describe the methods for generating slice cultures and quantifying neuronal injury.
Organotypic Culture of Full-thickness Adult Porcine Retina
1Neurology and Neurosciences, University of Medicine and Dentistry of New Jersey - UMDNJ, 2Institute of Ophthalmology and Visual Science, University of Medicine and Dentistry of New Jersey - UMDNJ
Here we describe a cost-effective technique for organotypic culture of adult porcine retina for seven days. Briefly, a sterile filter paper was used to lift the neural retina off from the RPE and place photoreceptor side up on an insert raised by a custom-made stand.
Organotypic Cerebellar Cultures: Apoptotic Challenges and Detection
1Laboratory of Genetics, The Salk Institute for Biological Studies, 2Clayton Foundation Laboratories for Peptide Biology, The Salk Institute for Biological Studies
This method describes the generation of organotypic cerebellar cultures and the effect of certain apoptotic stimuli on the viability of different cerebellar cell types.
Whole Cell Recording from an Organotypic Slice Preparation of Neocortex
Department of Anatomy and Neurobiology, University of Tennessee Health Science Center
This is a protocol to prepare and maintain a neocortical slice preparation in organotypic culture for the purpose of making electrical recordings from pyramidal neurons.
Multi-electrode Array Recordings of Neuronal Avalanches in Organotypic Cultures
Section on Critical Brain Dynamics, National Institute of Mental Health
A robust way to study neuronal avalanches, i.e. scale-invariant spatio-temporal activity bursts, indicative of critical state dynamics in cortex. Avalanches emerge spontaneously in developing superficial layers of cultured cortex which allows for long-term measurements of the activity with planar integrated multi-electrode arrays (MEA) under precisely controlled conditions.
Methods for Study of Neuronal Morphogenesis: Ex vivo RNAi Electroporation in Embryonic Murine Cerebral Cortex
1Department of Molecular, Cellular Biology and Biochemistry, Brown University , 2Institute for Brain Science, Brown University , 3Department of Psychiatry and Human Behavior, Warren Alpert School of Medicine, Brown University
To conduct a rapid assessment of the function of genes in the development of cerebral cortex, we describe methods involving the ex vivo electroporation of plasmids co-expressing inhibitory RNA (RNAi) and GFP in murine embryonic cortex. This protocol is amenable to the study of various aspects of neurodevelopment such as neurogenesis, neuronal migration and neuronal morphogenesis including dendrite and axon outgrowth.
Organotypic Slice Culture of E18 Rat Brains

Culturing and Applications of Rotating Wall Vessel Bioreactor Derived 3D Epithelial Cell Models
Basic Medical Sciences, University of Arizona College of Medicine - Phoenix
A rotating cell culture system that allows epithelial cells to grow under physiological conditions resulting in 3-D cellular aggregate formation is described. The aggregates generated display in vivo-like characteristics not observed in conventional culture models and serve as a more accurate organotypic model system for a multitude of scientific investigations.
