Electrophysiological Characterization Of Enteric Neurons Isolated From The Immortomouse, Edward G. Hawkins
Theses and Dissertations
The availability of murine genetic models is extremely advantageous to studying gastrointestinal function, but the benefits afforded by studying enteric neurons in mice has been hindered by their accessibility. Fetal (E13) and 2 day post-natal (P2) enteric neuron cell lines (IM-FEN and IM-PEN, respectively) were recently developed from the H-2Kb-tsA58 immortomouse. Our goal was to identify the electrophysiological properties of these cell lines and clarify their utility as a model of enteric neurons. IM-PEN cells stained positively for the neuron specific markers βIII-tubulin and PGP9.5 and were negative for the glial cell marker S100. Detection of mRNA for TRPA1, TRPV1, …
