<p class="jove_step">1.	Preparation for the dissection:</p>
<ol>
<li>Select the appropriate culture dish (10 cm or 6-well or 24-well plates, etc.) depending on the nature of your experiments, and coat them with rat-tail collagen 24 hours before dissection.  The methods for preparing rat-tail collagen and using it to coat culture dishes have been described elsewhere (1).</li>

<p class="jove_content">We use Sprague Dawley rats for our cultures.</p>
<p class="jove_content">Take time and care when cleaning the ganglia.  Remove all debris, blood vessels and fat.  This step is important in ensuring a culture that is more or less homogeneous and free of extraneous cell types.  The addition of uridine/5-FDU will largely eliminate any remaining non-neuronal (mitotic) cells contaminating the culture or at least suppress their proliferation.</p>

protocol for culturing sympathetic neurons from rat superior cervical ganglia (scg)

The superior cervical ganglia (SCG) in rats are small, glossy, almond-shaped structures that contain sympathetic neurons.  These neurons provide sympathetic innervations for the head and neck regions and they constitute a well-characterized and relatively homogeneous population (4).  Sympathetic neurons are dependent on nerve growth factor (NGF) for survival, differentiation and axonal growth and the wide-spread availability of NGF facilitates their culture and experimental manipulation (2, 3, 6).  For these reasons, cultured sympathetic neurons have been used in a wide variety of studies including neuronal development and differentiation, mechanisms of programmed and pathological cell death, and signal transduction (1, 2, 5, and 6).  Dissecting out the SCG from newborn rats and culturing sympathetic neurons is not very complicated and can be mastered fairly quickly.  In this article, we will describe in detail how to dissect out the SCG from newborn rat pups and to use them to establish cultures of sympathetic neurons.  The article will also describe the preparatory steps and the various reagents and equipment that are needed to achieve this.
