Abstract
The sympathetic nervous system inhibits gut motility, secretion, and blood flow in the gut microvasculature and can modulate gastrointestinal inflammation. Sympathetic neurons signal via catecholamines, neuropeptides, and gas mediators. In the current review, we summarize the current understanding of the mature sympathetic innervation of the gastrointestinal tract with a focus mainly on the prevertebral sympathetic ganglia as the main output to the gut. We also highlight recent work regarding the developmental processes of sympathetic innervation. The anatomy, neurochemistry, and connections of the sympathetic prevertebral ganglia with different parts of the gut are considered in adult organisms during prenatal and postnatal development and aging. The processes and mechanisms that control the development of sympathetic neurons, including their migratory pathways, neuronal differentiation, and aging, are reviewed.

Abstract
BACKGROUND The adrenal chromaffin cells synthesize, store and secrete a complex mixture containing amines, structural proteins, enzymes, and neurohormonal polypeptides. Most of the studies dealing with the development of the avian sympathoadrenal system have been based on antibodies recognizing signal molecules like HNK-1, NC-1, and N-CAM. METHODS The development of the chick sympathoadrenal system was studied from 3 1/2 to 21 days of incubation, both morphologically and immunocytochemically, using antibodies to 17 separate antigens, including antibodies to pan-neuroendocrine markers, catecholamine synthesizing enzymes, proprotein-processing enzymes, and neuropeptides. RESULTS Some of the antigens studied were heavily expressed from the first days of development, e.g., chromogranin-A, chromogranin-B, Go protein-alpha subunit, tyrosine hydroxylase, and galanin, while for others a strong heterogeneity both in number of immunoreactive cells and intensity of immunostaining was recorded at the different stages, e.g., dopamine-beta-hydroxylase,, 7B2 protein, proprotein convertase 2, somatostatin, met-enkephalin, secretogranin II, proprotein convertase 3, neuropeptide Y, phenyl-N-methyl transferase, and neuron-specific enolase. The first immunoreactivities to appear at day 3 1/2 were those for HNK-1, tyrosine hydroxylase, chromogranin-A, and chromogranin-B. Except for HNK-1, immunoreactivity for all the remaining antigens showed a steady increase up to the hatching. CONCLUSIONS Three expression patterns were found, in the developmental adrenal-gland: defining early permanent markers (chromogranin-A, chromogranin-B, Go protein-alpha subunit, tyrosine hydroxylase, and galanin), others that show a progressively increased expression until the day 10 of development (dopamine-beta-hydroxylase, 7B2 protein, proprotein convertase 2, somatostatin, met-enkephalin), and late-appearing antigens (secretogranin II, proprotein convertase 3, neuropeptide Y, phenyl-N-methyl transferase, and neuron-specific enolase).

Abstract
Since information about possible regional differences in the innervation of the guinea-pig large intestine is incomplete, a comparative study was made of the occurrence of neurones and nerve fibres of the submucosa showing immunoreactivity (IR) to neuropeptide Y (NPY) and vasoactive intestinal polypeptide (VIP). In addition, a quantitative analysis was made of submucosal neurones in regions of guinea-pig large intestine selected for probable differences in their function. There were two principal findings: First, the density of NPY-IR neurone somata was high in the ascending colon (mean +/- SEM 3148 +/- 464 neurones/cm2; n = 5 animals) and progressively declined in an anal direction, the descending colon having 348 +/- 125 neurones/cm2 (in the same 5 animals); immunoreactive cell bodies were rare in the rectum. The reduced density was also reflected in a fall in the number of NPY-IR neurones/ganglion from 3.0 +/- 0.3 in the ascending colon to 0.5 +/- 0.2 in the descending colon. Second, varicose NPY-IR intraganglionic fibres were a conspicuous feature of the duodenum, caecum, transverse colon, descending colon and rectum, but not of the ileum, ascending colon or distal spiral. Moreover, in the descending colon and rectum the fibres were arranged in a loose 'cobweb' structure around non-NPY-IR neurone somata; in the caecum, there was an apparent paucity of NPY-IR somata but the exceptionally dense intraganglionic varicose fibre network may have obscured NPY-IR somata. In all regions, fibre baskets were rare. In the ascending colon, only 25 +/- 5% of ganglia (compared to 92 +/- 2% of ganglia in the descending colon) showed any intraganglionic nerve fibres; furthermore, when they occurred, these were not of the 'cobweb' type but, rather, they gave the ganglia a speckled appearance. In very immature fetuses at a stage of development when no neuropeptide somata could be found in either the myenteric or submucosal plexuses, many NPY-IR nerve fibres were present in the submucosa with a distribution similar to that of adult guinea pigs. With respect to the density of VIP-IR neurones in the large intestine, there was only a 40% reduction in the number of neurones/cm2 from proximal to distal colon, in contrast to the corresponding 90% reduction in the density of NPY-IR neurones. The number of VIP-IR neurones/ganglion (6.4) and the proportion of ganglia with VIP-IR fibres (> 90%) were constant. It is concluded that the striking regional dissimilarities in (i) the occurrence of NPY-IR neurone somata and (ii) in the disposition of intraganglionic NPY-IR nerve fibres indicate potentially important regional differences in the functions of neuropeptide Y as an antisecretory peptide in the local regulation of chloride transport in the mucosa and as a modulator of ganglionic transmission, respectively.

Abstract
This study was undertaken in order to establish the presence of pluripotential neuroblasts in the developing chick CNS. This has been suggested by our previous observations that expression of emerging neuronal phenotypes in the chick embryo CNS is affected by exposure to neurotrophic substances (i.e., GHRH, SRIF, NGF, EGF, muscle-derived factors) or neurotoxins such as ethanol. We have proposed that one mechanism whereby these substances elicit their effects is by shifting phenotypic expression in populations of pluripotential neuroblasts. In order to establish the presence of significant populations of pluripotential neuroblasts, cultures obtained from 3-day-old whole chick embryos (E3WE) were double-stained with antibodies to markers specific for four neuronal phenotypes in various permutations. Cultures at 6 DIV were tested for the presence of tyrosine hydroxylase (TH), choline acetyltransferase (ChAT), gamma-aminobutyric acid (GABA), and somatostatin (SRIF) alone, and in various combinations. We observed a colocalization of all phenotypic markers within neuronal perikarya and processes in more than fifty percent of neuronal cells in these cultures. These data suggest that developing neuroblasts at this stage of embryogenesis possess the machinery necessary to adopt multiple neuronal phenotypes. The colocalization of neurotransmitter proteins in early neuroblasts (60 hr of embryogenesis) supports the recent concept that these substances themselves may influence phenotypic expression and also supports our idea that microenvironmental factors (i.e., ethanol, growth factors) provide signals which affect emerging phenotypes.

Abstract
Depolarizing stimuli are among the factors known to influence the phenotypic plasticity of nerve cells. In order to determine the prevalence of the depolarization effects in terms of cell and neuropeptide phenotypes, we have analyzed the effect of potassium (K+)-induced depolarization on the avian sympathoadrenal system. The expression of three peptidergic phenotypes, somatostatin (SS), neuropeptide Y (NPY) and enkephalin (Enk) by two cell types, adrenal and sympathetic, was studied under different depolarizing regimens. Cells from the sympathetic paravertebral ganglion and adrenal gland of 10-11-day chick embryos were cultured and the peptide levels were measured by radioimmunoassays. Chronic depolarization causes differential effects on the peptidergic phenotypes increasing NPY and Enk but decreasing SS in both adrenal and sympathetic cultures. However, shorter exposures to depolarizing stimuli revealed diverse effects on NPY and Enk phenotypes and even between adrenal and sympathetic cells. Moreover, the maintenance of the effects after removal of the depolarizing stimuli showed additional differences among the phenotypes. Our results are not compatible with a previously established hypothesis stating that depolarization increases the synthesis of whichever neurotransmitters a neuron is already producing. They provide evidence indicating that the depolarization effect is much more complex than originally thought, and serve to initiate an in depth probe into the effect of depolarization of cellular plasticity.

Abstract
This study examines the properties of neurons differentiating in cultures of mammalian neural crest cells. The neurons fall into two categories: (1) a population of early differentiating (ED) neurons generated from precursors that are postmitotic at the time of plating; and (2) a late differentiating (LD) population of neurons arising from dividing precursor cells. The ED population of neurons survive for only 2-3 days while the LD neurons survive for many weeks. Both groups of neurons express the neuronal marker, neurofilament, as well as adrenergic and cholinergic characteristics. The latter two traits are evident as immunoreactivity for tyrosine hydroxylase (TH)/dopamine-beta-hydroxylase (D beta H) and choline acetyltransferase (ChAT), respectively. The LD neurons also contain immunoreactivity for a number of neuropeptides including, substance P (SP), neuropeptide Y (NPY), vasoactive intestinal polypeptide (VIP), calcitonin gene related polypeptide (CGRP), and somatostatin (SOM). Immunoreactivity for SP, CGRP, and VIP are found in virtually all of the LD neurons while SOM and NPY are found in a smaller percentage of the neurons.

Abstract
These studies sought to determine whether the cell bodies of rat superior cervical ganglion neurons projecting to three very different target organs differ in terms of their size, number, location within the ganglion and/or neuropeptide content, and whether these features are altered in response to neonatal deafferentiation of the ganglion. A series of retrograde tracer, immunocytochemical, and double-labeling studies revealed differences in the size, number, location and neuropeptide content of superior cervical ganglion neurons that project to the submandibular salivary glands, eyes, or pineal gland. The mean areas of the cell bodies of neurons projecting to the submandibular gland are largest, those projecting to the eye are smallest, and those projecting to the pineal are intermediate in size. Submandibular gland projecting neurons are found throughout the ganglion, while the eye and pineal projecting populations are localized to the rostral quadrants. The different subpopulations of target organ specific superior cervical ganglion neurons are heterogeneous in their content of vasoactive intestinal peptide-, neuropeptide Y- and somatostatin-like immunoreactivity. A greater percentage of submandibular gland than of pineal projecting neurons display vasoactive intestinal peptide-like immunoreactivity, but there are no differences in the percentage of neurons displaying neuropeptide Y- or somatostatin-like immunoreactivity between the target organ specific groups. Neonatal deafferentiation does not result in changes in the size, number or distribution of target organ specific neurons, or in the percentage of immunoreactive neurons in these populations. In conclusion, these studies provide evidence that the size and distribution of neurons and percentage of peptide-containing neurons in the superior cervical ganglion is related to the target organ innervated, but provides no evidence of exclusive target organ-peptide relationships.

Abstract
We have studied the expression and development of neuropeptide Y-like immunoreactivity (NPY-LI) in the sympathoadrenal system of the chicken using single and double immunocytochemical techniques and radioimmunoassay. NPY-LI is expressed by neurons of the paravertebral sympathetic ganglia and by chromaffin cells of the adrenal gland in embryonic and adult chickens. The peptide is coexpressed with catecholaminergic properties in neurons. In chromaffin cells, it is also expressed with immunoreactivity to somatostatin and serotonin. We have used the expression of NPY-LI to analyze how cells that coexpress two or more neuroactive substances arrive at their final phenotype. Our results suggest that the ontogeny of coexpression in neurons of the avian paravertebral sympathetic ganglia occurs in a sequential pattern, where the expression of the peptide follows the initial expression of the “classical neurotransmitter”. In contrast, in chromaffin cells, expression of the peptides occurs concomitantly with expression of catecholaminergic properties or soon after. Initially, coexpression of several neuroactive substances occurs, but this is followed by further specialization where the expression of one peptide prevails over the other. We believe that the two models of coexpression shown by our results can be used to describe the ontogeny of coexpression in other cells of the nervous system.

Abstract
Immunofluorescence was used in the rat to study the early ontogenetic expression of somatostatin (SRIF) in the dorsal root ganglia (DRGs) from gestational day 10.5 to day 15.5. SRIF-immunoreactivity (IR) was not detectable in day-10.5 embryos, was first observed in DRGs at day 11.5, reached a peak in intensity and distribution at around day 13.5 and thereafter decreased to become undetectable by day 15.5 in the DRGs of the trunk region. The dynamic expression of SRIF-IR in DRG perikarya could be correlated with its expression in nerve fibers located in the limbs and the abdominal mesenchyme. Thus, SRIF-IR is expressed at a time when sensory fibers could have established connections with their embryonic targets and when DRG neurons could have undergone their final mitotic phase. These data showing the earliest and transient expression of a neuropeptide in developing DRGs confirm and extend the notion that SRIF plays an important role in developmental processes.

Abstract
We have shown that the endogenous neuropeptides, growth hormone-releasing hormone (GHRH) and somatostatin (SRIF) influence expression of both cholinergic and catecholaminergic neuronal phenotypes in developing chick brain as assessed by the activities of choline acetyltransferase and tyrosine hydroxylase, respectively (Dev. Brain Res., 49 (1989) 275-280; Brain Research, 512 (1990) 297-303). In this study we examined the effects of GHRH and SRIF on GABAergic neuronal expression in ovo using activity of glutamate decarboxylase (GAD) as a neuronal marker. Chick embryos were administered GHRH or SRIF in ovo via the air sac on embryonic days 1, 3, 5 and 7, sacrificed at day 8 and the activity of GAD assayed in whole brain homogenates. GAD activity was significantly reduced in peptide-treated embryos as compared to controls. Similar results were obtained when GHRH was administered in a single dose at days 1 or 3 or when SRIF was administered in a single dose at day 3; GAD activity was significantly reduced as compared with control embryos. In contrast, embryos treated with either GHRH or SRIF on day 5 of development showed no difference in GAD activity as compared to controls. These data support our previous findings that endogenous neuropeptides such as GHRH and SRIF possess important properties with respect to neuronal phenotypic expression. They further define the critical period of sensitivity to these neuropeptides as 1-3 days of embryonic development.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Two distinct neuropeptide-related phenotypes are found in avian paravertebral sympathetic ganglia, corresponding to somatostatin- (SS) and vasoactive intestinal polypeptide- (VIP) expressing cells. We have detected the same cell phenotypes in cultures of embryonic quail sympathetic ganglia and have used this system to study the modulation of their expression by the environment. The cell phenotypes were identified using immunocytochemistry and induced catecholamine fluorescence and quantitative data were obtained by radioimmunoassay. Dissociation of the ganglia caused a profound increase in the expression of VIP but had no effect on SS levels. Addition of corticosterone (10(-6) M) increased the expression of SS without modifying VIP levels. In contrast, depolarization of the cells induced changes in levels of both neuropeptides. The modulation of VIP correlates with the modulation of cholinergic properties. The regulation of neuropeptide expression in the avian system shows both similarities and differences to what has been found in the mammalian system.

Abstract
Considering the initial expression of neurotransmitters and neuropeptides immediately after neural induction in amphibian embryos, we previously pointed out that a neuronal cell population emerges from neural plate (NP) and neural fold (NF) expressing very early specific cholinergic, catecholaminergic, GABAergic and peptidergic traits. The purpose of the present work was to investigate the extent to which the neuroblasts that are present in the neurectoderm immediately after gastrulation are committed to give rise to multiple subsets of neurons containing various combinations of neuroactive transmitters rather than to different subpopulations of neurochemically homogeneous neurons. By means of double immunocytochemical localization with a monoclonal TOH-antibody and polyclonal antibodies against GABA or somatostatin, no coexistence of neurotransmitters and neuropeptide was ever found in neuronal subpopulations arising in vitro from NP or NF. The early emergence, under the same conditions, of distinct neuronal subpopulations as a consequence of neural induction strongly suggests that, at the gastrula stage, the neural precursor population most probably does not constitute a homogeneous set of cells.

Abstract
The avian sympathoadrenal system has been used as a model to examine the differentiation of cells expressing neuroactive substances derived from the neural crest. Previous studies have dealt with the expression of the "classical" neurotransmitters acetylcholine and catecholamines and of the neuropeptides somatostatin and vasoactive intestinal polypeptide. We have used immunocytochemistry to examine the developmental expression of the monoamine serotonin (5HT) in the chicken sympathoadrenal system. 5HT-like immunoreactivity (5HT-LI) was found to be transiently expressed by cells of the sympathetic ganglia very early in development (E-5 to E-8), disappearing almost entirely at more advanced embryonic stages (E-10 to E-19) and post-hatched chickens where only a population of cells similar to mammalian small intensely fluorescent cells express immunoreactivity to the amine. In contrast, in the adrenal gland of embryos and post-hatched chickens, most chromaffin cells also express 5HT-LI. Double labeling experiments show that in both the adrenal gland and the sympathetic ganglia catecholaminergic properties and somatostatin immunoreactivity are co-expressed with 5-HT-LI. Moreover, the cells that transiently express 5HT-LI in sympathetic ganglia also transiently express somatostatin. The catecholaminergic cells expressing serotonin and somatostatin appear to define a biochemical phenotype common to some chromaffin cells, small intensely fluorescent cells and early sympathoblasts.

Abstract
The neural crest-derived precursors of the sympathoadrenal lineage depend on environmental cues to differentiate as sympathetic neurons and pheochromocytes. We have used the monoclonal antibody A2B5 as a marker for neuronal differentiation and antisera against catecholamine synthesis enzymes to investigate the differentiation of catecholaminergic cells in cultures of quail neural crest cells. Cells corresponding phenotypically to sympathetic neurons and pheochromocytes can be identified in neural crest cell cultures after 5-6 days in vitro. Expression of the A2B5 antigen precedes expression of immunocytochemically detectable levels of tyrosine hydroxylase in cultured neural crest cells. Glucocorticoid treatment decreases the proportion of TH+ neural crest cells that express neuronal traits. We conclude that environmental cues normally encountered by sympathoadrenal precursors in vivo can influence the differentiation of a subpopulation of cultured neural crest cells in the sympathoadrenal lineage.

Abstract
The embryonic neural crest of vertebrates is the source of a wide variety of adult cell types. We have demonstrated previously that the presence of a reconstituted basement-membrane-like (RBM) gel overlay can dramatically stimulate the development of adrenergic cells in neural crest cultures grown in a complex medium containing horse serum and chick embryo extract. In the present experiments we have analyzed the differentiation of neural crest cells grown in a defined medium with an RBM gel overlay. We found that the presence of the RBM gel promoted the development of catecholamine-containing (CA+) cells in neural crest cultures grown in defined medium compared to cultures grown in this same medium in the absence of the gel. The number of CA+ cells which developed in cultures grown in defined medium in the presence of the RBM gel overlay was similar to that seen in cultures grown in complex medium in the absence of the RBM gel.

Somatostatin immunoreactivity was studied in the avian ciliary ganglion by immunocytochemistry and radioimmunoassay. Immunoreactivity was localized to small diameter cell bodies of neurons from embryos, newly-hatched and adult preparations. Immunostaining of ganglia with a mixture of antisera to substance P and monoclonal antibody to somatostatin indicated that a number of somatostatin-immunoreactive neurons were surrounded by substance P-immunoreactive boutons, which characteristically terminate on choroidal neurons. Staining with a mixture of antisera to choline acetyltransferase and antibody to somatostatin showed that the somatostatin-immunoreactive neurons were less intensely-stained for choline acetyltransferase than were the neurons lacking somatostatin immunoreactivity. Bundles of nerve fibers showing somatostatin and choline acetyltransferase immunoreactivity were found in the choroid layers of the eye. Radioimmunoassay indicated the presence of somatostatin immunoreactivity in both chick and quail ganglia; the somatostatin immunoreactivity eluted from high pressure liquid chromatography in the same positions as authentic somatostatin 14 and 28. These results show that somatostatin is contained in cholinergic choroidal neurons in the chick and quail ciliary ganglion.

Abstract
Qualitative and quantitative in vivo studies were performed on the development of the neuropeptide vasoactive intestinal polypeptide (VIP) in the peripheral nervous system of quail embryos. VIP-like immunoreactivity (VIPLI) was found by radioimmunoassay (RIA) from the sixth day of embryonic life onward in the sympathetic chain, the esophagus and duodenum, and from day 15 of incubation onward in the adrenal glands and the nodose ganglia. By using immunocytochemistry, we identified cells expressing VIPLI in sensory spinal ganglia of 13- to 15-day-old embryos. In neural crest cultures, cells expressing the VIP phenotype differentiated constantly under various culture conditions, in contrast to other phenotypes which had specific medium requirements, i.e. adrenergic cells or substance P-containing neurons.

Abstract
The pathophysiology of Hirschsprung's disease has not been fully elucidated but is known to have a neurogenic basis. In recent years, new neural proteins and peptides have been discovered and our aim in this study was to use immunocytochemistry to investigate their involvement in the neuronal abnormalities associated with this condition. Large bowel samples from 9 children undergoing surgery for Hirschsprung's disease were compared with those taken from 8 children with other gastrointestinal diseases but no aganglionosis. Immunocytochemistry was carried out using antibodies to a wide range of neuron specific proteins and peptides. Examination of sections immunostained for the general neuronal markers, protein gene product 9.5, neuron specific enolase and neurofilament triplet proteins, allowed rapid identification of aganglionic segments. Nerves containing vasoactive intestinal polypeptide/peptide histidine methionine (VIP/PHM), galanin, substance P, somatostatin, met-enkephalin or calcitonin gene-related peptide (CGRP) showed a marked reduction in all layers of the aganglionic bowel. However, scattered VIP/PHM immunoreactive fibres were also found in the hypertrophied nerve bundles. In contrast with these reduced peptide-containing nerves, fibres displaying NPY immunoreactivity showed a marked increase in all aganglionic segments, particularly in the circular muscle where few are found normally. Our findings shed further light on the neurobiology of aganglionic bowel and suggest that immunostaining of neural proteins and the peptide NPY can aid rapid histopathological diagnosis of congenital aganglionosis.
