“…The results obtained by us in gazelle dama are consistent with those observed in sheep (Ibrahim, 2018), cows (Jang et al, 2021), Asian roe deer (Park et al, 2014a) and Korean black goats (Park et al, 2013). PGP 9.5-positive cells show strong immunoreactivity in their soma, dendrites, and their axons which extend through the lamina.…”

“…His description of the rostral part as a cuboidal stratified epithelium of cells with lightly stained cytoplasm coincides what we have observed in the dama gazelle. Likewise, his description as well as that of other authors in cows (Taniguchi & Mikami, 1985;Salazar et al, 2008;Jang et al, 2021) regarding the organization the neuroepithelium in basal, neuroreceptor and sustentacular cells, and the organization of the respiratory epithelium coincides with that observed by us. This is as well comparable to that observed in other Bovinae such as goat (Park et al, 2013), sheep (Kratzing, 1971;Salazar et al, , 2000Salazar, Lombardero, Alemañ, et al, 2003;Salazar et al, 2007;Ibrahim et al, 2013;Ibrahim, 2018) and water buffalo (Emam et al, 2016), but also with the other ruminants studied, such as giraffe (Kondoh, Nakamura, et al, 2017), reindeer (Bertmar, 1981), elk (Vedin et al, 2010) and Korean roe deer (Park et al, 2014a), which shows that we are dealing with a widely conserved pattern in ruminant evolution.…”

“…These results show differences and similarities with the labelling obtained by these lectins in the VNO of other ruminant mammalian species. For this reason, our findings are related below to existing information on sheep (Ovis orientalis aries) (Salazar et al, 2000(Salazar et al, , 2007Ibrahim et al, 2013), cow (Bos taurus coreanae) (Jang et al, 2021), goat (Capra aegagrus hircus) (Park et al, 2013;Yang et al, 2021) and Asian roe deer (Capreolus pygargus) (Park et al, 2014b;Shin et al, 2017).…”

“…These findings were found in the VNO of cow and horse, which also showed PAS-positive glands . Subsequently, several authors obtained the same results by finding both types of VG in all the ruminants studied: cow (Salazar et al, 2008;Jang et al, 2021), sheep (Salazar et al, 2000(Salazar et al, , 2007, goat (Yang et al, 2021), silka deer (Kondoh et al, 2020), giraffe (Kondoh, Nakamura, et al, 2017), and goitered gazelle (Abood & Hussein, 2018). The degree of development of the glands and the intensity of the response to both stainings, PAS and AB, was similar for all species.…”

“…Anti-OMP stained cell bodies more intensely than dendrites in OMP-positive receptor cells. This feature was also found in sheep (Ibrahim, 2018), cow (Jang et al, 2021), and roe deer (Shin et al, 2017), however, goat showed the reverse pattern (Park et al, 2013;Yang et al, 2021). Anti-OMP immunolabelling in the RE shows variations between the different ruminants.…”

The dama gazelle is a threatened and scarcely studied species of northern Africa. Human pressure has depleted the population of dama gazelles from tens of thousands to a few hundred individuals. Since 1970, after deriving from a founder population of the last 17 surviving individuals in the Western Sahara, it has been reproduced naturally in captivity. Although certain aspects of the reproductive biology of the dama gazelle have been established in preparation for the future implementation of assisted reproductive technology there is a lack of information regarding the role of semiochemical-mediated communication in the sexual behavior of the dama gazelle. This is partially due to the lack of a neuroanatomical and morphofunctional characterization of the dama gazelle vomeronasal organ (VNO); the sensory organ responsible for the processing of pheromones. This study aims to determine the presence in the dama gazelle of a VNO fully equipped to carry out its neurosensory function and to contribute to the understanding of the interspecific variability of the VNO of ruminants. Employing histological, lectin-histochemical and immunohistochemical techniques we have performed a detailed morphofunctional evaluation of the dama gazelle VNO along its entire longitudinal axis. The findings suggest that studies of the VNO should take a similar approach, as there are significant structural and neurochemical transformations that the organ exhibits as a whole. This study contributes to the understanding of the VNO in dama gazelles and provides a basis for future studies on semiochemical-mediated communication and reproductive management of this species.

Dama gazelle is a threatened and rarely studied species found primarily in northern Africa. Human pressure has depleted the dama gazelle population from tens of thousands to a few hundred individuals. Since 1970, a founder population consisting of the last 17 surviving individuals in Western Sahara has been maintained in captivity, reproducing naturally. In preparation for the future implementation of assisted reproductive technology, certain aspects of dama gazelle reproductive biology have been established. However, the role played by semiochemical‐mediated communications in the sexual behavior of dama gazelle remains unknown due partially to a lack of a neuroanatomical or morphofunctional characterization of the dama gazelle vomeronasal organ (VNO), which is the sensory organ responsible for pheromone processing. The present study characterized the dama gazelle VNO, which appears fully equipped to perform neurosensory functions, contributing to current understanding of interspecies VNO variability among ruminants. By employing histological, lectin‐histochemical, and immunohistochemical techniques, we conducted a detailed morphofunctional evaluation of the dama gazelle VNO along its entire longitudinal axis. Our findings of significant structural and neurochemical transformation along the entire VNO suggest that future studies of the VNO should take a similar approach. The present study contributes to current understanding of dama gazelle VNO, providing a basis for future studies of semiochemical‐mediated communications and reproductive management in this species.Research Highlights This exhaustive immunohistological study of the vomeronasal organ (VNO) of the dama gazelle provides the first evidence of notable differences in the expression of neuronal markers along the rostrocaudal axis of the VNO. This provides a morphological basis for the implementation of pheromones in captive populations of dama gazelle.

Introduction: The detection of chemical signals by the vomeronasal organ (VNO) is critical for mammals from an early age, influencing behaviors such as suckling and recognition of the mother. Located at the base of the nasal cavity, the VNO features a duct covered with a sensory epithelium. A critical aspect of VNO functionality is the efficient access of stimuli from the nasal and oral cavities to the receptors. In adult dogs, it has been demonstrated how the VNO duct (VD) communicates to the environment through the incisive duct (ID). In newborn puppies, the existence of functional communication between the ID and the VD has not been confirmed to date, raising doubts about the potential physiological obliteration of the ID. Determining this aspect is necessary to evaluate the role played by chemocommunication in the survival and socialization of puppies. Methods: This study employs serial histological staining to examine the presence and functionality of the ID in neonatal dogs. Additionally, a histochemical study was conducted using PAS and Alcian Blue staining, along with labelling with six lectins to characterize the expression of glycoconjugates in the incisive papilla and in the area between the ID and the VD. Results: The histological study has confirmed both the existence of functional communication between both ducts in perinatal puppies, and the dual functional communication of the ID with the oral and nasal cavities. The ID is associated with a sophisticated cartilaginous complex that prevents its collapse, as well as erectile tissue that acts as a cushion, facilitating its action under pressure induced by sampling behaviors such as tonguing. Lectin labelling has allowed for the characterization of the glycoconjugate expression profile in the papilla and ID, showing significant differences between lectins . Discussion: This investigation demonstrates the communicative capabilities of the VNO during the perinatal stage in dogs.
