Abstract
The enteric nervous system (ENS) is a complex series of interconnected neurons and glia that reside within and along the entire length of the gastrointestinal tract. ENS functions are vital to gut homeostasis and digestion, including local control of peristalsis, water balance, and intestinal cell barrier function. How the ENS develops during embryological development is a topic of great concern, as defects in ENS development can result in various diseases, the most common being Hirschsprung disease, in which variable regions of the infant gut lack ENS, with the distal colon most affected. Deciphering how the ENS forms from its progenitor cells, enteric neural crest cells, is an active area of research across various animal models. The vertebrate animal model, zebrafish, has been increasingly leveraged to understand early ENS formation, and over the past 20 years has contributed to our knowledge of the genetic regulation that underlies enteric development. In this review, I summarize our knowledge regarding the genetic regulation of zebrafish enteric neuronal development, and based on the most current literature, present a gene regulatory network inferred to underlie its construction. I also provide perspectives on areas for future zebrafish ENS research.

Abstract
For the digestion of food, it is important for the gut to be differentiated regionally and to have proper motor control. However, the number of transcription factors that regulate its development is still limited. Meanwhile, the interstitial cells of the gastrointestinal (GI) tract are necessary for intestinal motility in addition to the enteric nervous system. There are anoctamine1 (Ano1)-positive and platelet-derived growth factor receptor α (Pdgfra)-positive interstitial cells in mammal, but Pdgfra-positive cells have not been reported in the zebrafish. To identify new transcription factors involved in GI tract development, we used RNA sequencing comparing between larval and adult gut. We isolated 40 transcription factors that were more highly expressed in the larval gut. We demonstrated expression patterns of the 13 genes, 7 of which were newly found to be expressed in the zebrafish larval gut. Six of the 13 genes encode nuclear receptors. The osr2 is expressed in the anterior part, while foxP4 in its distal part. Also, we reported the expression pattern of pdgfra for the first time in the larval zebrafish gut. Our data provide fundamental knowledge for studying vertebrate gut regionalization and motility by live imaging using zebrafish.

Abstract
The enteric nervous system is a vast intrinsic network of neurons and glia within the gastrointestinal tract and is largely derived from enteric neural crest cells (ENCCs) that emigrate into the gut during vertebrate embryonic development. Study of ENCC migration dynamics and their genetic regulators provides great insights into fundamentals of collective cell migration and nervous system formation, and these are pertinent subjects for study due to their relevance to the human congenital disease Hirschsprung disease (HSCR). For the first time, we performed in toto gut imaging and single-cell generation tracing of ENCC migration in wild type and a novel ret heterozygous background zebrafish (retwmr1/+) to gain insight into ENCC dynamics in vivo. We observed that retwmr1/+ zebrafish produced fewer ENCCs localized along the gut, and these ENCCs failed to reach the hindgut, resulting in HSCR-like phenotypes. Specifically, we observed a proliferation-dependent migration mechanism, where cell divisions were associated with inter-cell distances and migration speed. Lastly, we detected a premature neuronal differentiation gene expression signature in retwmr1/+ ENCCs. These results suggest that Ret signaling may regulate maintenance of a stem state in ENCCs.

Development 2021; 148:dev.195339.

Abstract
The enteric nervous system (ENS), which is derived from neural crest, is essential for gut function, and its deficiency causes severe congenital diseases. Since the capacity for ENS regeneration in mammals is limited, additional complementary models would be useful. Here, we show that the ENS in zebrafish larvae at 10-15 days postfertilization is highly regenerative. After laser ablation, the number of enteric neurons recovered to ∼50% of the control by 10 days post-ablation (dpa). Using transgenic lines in which enteric neural crest-derived cells (ENCDCs) and enteric neurons are labeled with fluorescent proteins, we live imaged the regeneration process and found covering by neurites that extended from the unablated area and entry of ENCDCs into the ablated areas by 1-3 dpa. BrdU assays suggested that ∼80% of the enteric neurons and ∼90% of the Sox10-positive ENCDCs therein at 7 dpa were generated through proliferation. Thus, ENS regeneration involves proliferation, entrance and neurogenesis of ENCDCs. This is the first report regarding the regeneration process of the zebrafish ENS. Our findings provide a basis for further in vivo research at single-cell resolution in this vertebrate model.

Abstract
The Enteric Nervous System (ENS) is a large network of enteric neurons and glia that regulates various processes in the gastrointestinal tract including motility, local blood flow, mucosal transport and secretion. The ENS is derived from stem cells coming from the neural crest that migrate into and along the primitive gut. Defects in ENS establishment cause enteric neuropathies, including Hirschsprung disease (HSCR), which is characterized by an absence of enteric neural crest cells in the distal part of the colon. In this review, we discuss the use of zebrafish as a model organism to study the development of the ENS. The accessibility of the rapidly developing gut in zebrafish embryos and larvae, enables in vivo visualization of ENS development, peristalsis and gut transit. These properties make the zebrafish a highly suitable model to bring new insights into ENS development, as well as in HSCR pathogenesis. Zebrafish have already proven fruitful in studying ENS functionality and in the validation of novel HSCR risk genes. With the rapid advancements in gene editing techniques and their unique properties, research using zebrafish as a disease model, will further increase our understanding on the genetics underlying HSCR, as well as possible treatment options for this disease.

Abstract
Foodborne enteritis has become a limiting factor in aquaculture. Plant protein sources have already caused enteritic inflammation and inhibition in growth performance. Attempts have been made to find an effective solution to foodborne enteritis. Based on the previously suggested fish cholinergic anti-inflammatory pathway, galantamine, a typical cholinesterase inhibitor, was tested for the repression of pro-inflammatory cytokines for soybean meal induced enteritis by injection into grass carp. Both the phylogenetic analysis of cholinesterase, AchR and bioinformatic prediction, indicated galantamine's potential use as an enteritis drug. The result highlighted galantamine's potential effect for anti-enteritis in fish, especially in carps. Subsequently, a 4-week feeding trail using galantamine as an additive, in a zebrafish soybean meal induced enteritis model, demonstrated the prevention of enteritis. The results demonstrated that galantamine could prevent intestinal pathology, both histologically and molecularly, and also maintain growth performance. Reflected by gene expressional analysis, all mechanical, chemical and immune functions of the intestinal barrier could be protected by galantamine supplementation, which aided molecularly in the control of fish foodborne enteritis, through down-regulating Th17 type proinflammatory factors, meanwhile resuming the level of Treg type anti-inflammatory factors. Therefore, the current results shed light on fish intestinal acetylcholine anti-inflammation, by the dietary addition of galantamine, which could give rise to protection from foodborne enteritis.

Abstract
BACKGROUND The enteric nervous system (ENS) is derived from enteric neural crest cells (ENCCs) that migrate into the gut. The zebrafish larva is a good model to study ENCC development due to its simplicity and transparency. However, little is known how individual ENCCs divide and become neurons. RESULTS Here, by applying our new method of local heat-shock mediated Cre-recombination around the dorsal vagal area of zebrafish embryos we produced multicolored clones of ENCCs, and performed in vivo time-lapse imaging from ca. 3.5 to 4 days post-fertilization after arrival of ENCCs in the gut. Individual ENCCs migrated in various directions and were highly intermingled. The cell divisions were not restricted to a specific position in the gut. Antibody staining after imaging with anti-HuC/D and anti-Sox10 showed that an ENCC produced two neurons, or formed a neuron and an additional ENCC that further divided. At division, the daughter cells immediately separated. Afterward, some made soma-soma contact with other ENCCs. CONCLUSIONS We introduced a new method of visualizing individual ENCCs in the zebrafish gut, describing their behaviors associated with cell division, providing a foundation to study the mechanism of proliferation and neurogenesis in the ENS in vertebrates.
