Preparation of Primary Cultures of Embryonic Rat Hippocampal and Cerebrocortical Neurons
[Abstract]  This protocol aims at standardizing the procedure to obtain primary cultures of hippocampal and cerebrocortical neurons for in vitro experiments. Cultures should be prepared from cells isolated during embryonic development when neuronal precursor cells are not yet fully differentiated. This helps increasing the quality and quantity of cells, while offering minimal cell death that often occurs during dissociation of differentiated neurons. Cells plated under the appropriate conditions, either in Petri-dishes or in multi-well plates, will develop and establish synaptic contacts over time since the neuronal culture medium provides the nutrients and trophic factors required for differentiation. In this protocol we describe the methodology for the preparation of both cortical and ...

Three Dimensional Spheroid Co-culture Invasion Assay
[Abstract]  The assay was developed to investigate the impact of stromal cells of different types (in our case breast cancer associated fibroblasts stably manipulated to modify expression of genes of interest) on the invasive capacity of epithelial cancer cells (in our case breast cancer cell lines) (Verghese et al., 2013). Typical two dimensional invasion assays do necessarily account for the presence of extracellular matrix that is present around the stromal and tumour cells in vivo and therefore cellular behaviour within these cultures may be non-physiological. This spheroid assay was developed to attempt to replicate more closely the environment that is present around breast cancer stromal and tumour cells in actual tumours (Verghese et al., 2013). Extra cellular ...
