Fluidic Logic Used in a Systems Approach to Enable Integrated Single-Cell Functional Analysis.

The study of single cells has evolved over the past several years to include expression and genomic analysis of an increasing number of single cells. Several studies have demonstrated wide spread variation and heterogeneity within cell populations of similar phenotype. While the characterization of these populations will likely set the foundation for our understanding of genomic- and expression-based diversity, it will not be able to link the functional differences of a single cell to its underlying genomic structure and activity.

Enhanced expression of CGRP in rat trigeminal ganglion neurons during cell and organ culture.

The sensory innervation of intracranial vessels originates in the trigeminal ganglion with calcitonin gene-related peptide (CGRP), substance P (SP) and pituitary adenylate cyclase activating peptide (PACAP) as frequent neuronal messengers. The present study was designed to study the expression of these neuropeptides (a) in primary culture of adult rat trigeminal ganglion neuronal cells and (b) in organ culture of sections of the trigeminal ganglion. In cell culture, axons grow in the peripheral direction for up to 48 h.

Expression of inducible nitric oxide synthase in trigeminal ganglion cells during culture.

Nitric oxide (NO) is an important signalling molecule that has been suggested to be a key molecule for induction and maintenance of migraine attacks based on clinical studies, animal experimental studies and the expression of nitric oxide synthase (NOS) immunoreactivity within the trigeminovascular system. Sensitisation of the trigeminal system including the trigeminal ganglia neurones is believed to be involved in the pathway leading to migraine pain. In the present study, the NOS expression in rat primary trigeminal ganglia neurones was examined at different time points using immunocytochemistry, reverse transcriptase polymerase chain reaction (RT-PCR) and Western blotting.
