“…In mammals, the psb is a complex region that might influence cell migration between the subpallium and pallium, and controls the migration of pallial cells ventrally to the striatum (Fishell et al, 1993; Chapouton et al, 1999; Marín and Rubenstein, 2003; Carney et al, 2006). In addition, in all the species analyzed Pax6 cells from the psb appear to migrate to specific emerging amygdaloid nuclei and other basal telencephalic structures (Carney et al, 2006; Ferreiro-Galve et al, 2008; Moreno et al, 2008; Rodríguez-Moldes, 2009; Quintana-Urzainqui et al, 2012b; Bandín et al, 2013, 2014; Joven et al, 2013a,b; present results). Therefore, the analysis of this psb zone in vertebrates with different pallial and subpallial features seems of great interest from a comparative perspective, because differences in the organization of the psb could be essential in the evolution of pallial differences.…”

“…The pallium seems to lose Pax6 expression in the subventricular zone after development, with the exception of the most ventral portion corresponding to the ventral pallium, in the psb zone. However, fragmentary data from elasmobranches ( Scyliorhinus canicula ; Ferreiro-Galve et al, 2008) and lungfishes ( Protopterus dolloi : González and Northcutt, 2009; N. forsteri : present results) suggest that abundant Pax6 expression remains in pallial cells after development.…”

Conserved localization of Pax6 and Pax7 transcripts in the brain of representatives of sarcopterygian vertebrates during development supports homologous brain regionalization

Many of the genes involved in brain patterning during development are highly conserved in vertebrates and similarities in their expression patterns help to recognize homologous cell types or brain regions. Among these genes, Pax6 and Pax7 are expressed in regionally restricted patterns in the brain and are essential for its development. In the present immunohistochemical study we analyzed the distribution of Pax6 and Pax7 cells in the brain of six representative species of tetrapods and lungfishes, the closest living relatives of tetrapods, at several developmental stages. The distribution patterns of these transcription factors were largely comparable across species. In all species only Pax6 was expressed in the telencephalon, including the olfactory bulbs, septum, striatum, and amygdaloid complex. In the diencephalon, Pax6 and Pax7 were distinct in the alar and basal parts, mainly in prosomeres 1 and 3. Pax7 specifically labeled cells in the optic tectum (superior colliculus) and Pax6, but not Pax7, cells were found in the tegmentum. Pax6 was found in most granule cells of the cerebellum and Pax7 labeling was detected in cells of the ventricular zone of the rostral alar plate and in migrated cells in the basal plate, including the griseum centrale and the interpeduncular nucleus. Caudally, Pax6 cells formed a column, whereas the ventricular zone of the alar plate expressed Pax7. Since the observed Pax6 and Pax7 expression patterns are largely conserved they can be used to identify subdivisions in the brain across vertebrates that are not clearly discernible with classical techniques.

“…Moreover, the patterns of expression of some early developmental genes have been reported in the eyes of S. canicula in very early developmental stages (Sauka-Spengler et al, 2001;Plouhinec et al, 2005). The development of GABAergic structures in the retina of the two sharks subject of this work has been already published (Ferreiro-Galve et al, 2008).…”

“…Cartilaginous fishes (including sharks) are anamniotes and would be expected to have similar retinal development to other fish species. However, the scant developmental studies of the morphogenesis of their retina have revealed differences with teleosts in the order of cell differentiation (Fishelson and Baranes, 1999;Harahush et al, 2009) and in the development of the GABAergic system (Ferreiro-Galve et al, 2008).…”

“…Projections from the reticular formation to the cerebellum have been reported in elasmobranchs (Fiebig, 1988). Considering that the optic tectum is the main retinorecipient center in the adult dogfish brain (Smeets, 1981) and that the serotoninergic innervation begins long after that the neuronal differentiation takes place in the dogfish retina (Ferreiro-Galve et al, 2008b), it is very improbable that serotonin is involved in early stages of maturation of the tectum, but it may be important for functional aspects of the mature tectum.…”

Chondrychthyans (cartilaginous fishes) are key to understanding the ancestral gnathostome condition since they provide an outgroup to sarcopterygians and actinopterygians. To gain comparative knowledge about the development of the vertebrate serotoninergic systems, we studied by immunohistochemistry the origin, spatiotemporal organization, and migration patterns of serotonin-containing neurons and the growth of axonal pathways in the central nervous system of a shark, the lesser spotted dogfish. Hindbrain serotonin-immunoreactive cells arose close to the floor plate and most populations migrated ventrally and mediolaterally to form the various raphe and reticular groups. The order of appearance of serotoninergic populations in the rhombencephalon and spinal cord (first the superior groups and then the inferior and spinal populations) roughly matched with that reported in other vertebrates but important differences were noted in the formation of prosencephalic groups in fishes. In addition to preoptic and hypothalamic areas, serotoninergic cerebrospinal fluid-contacting cells were observed in the isthmus (raphe dorsalis anterioris). Transient serotonin-immunoreactive cells were noted in the pineal organ, habenula, and pretectum. Further, we provide a revised anatomical framework for reticular and raphe serotoninergic populations considering their origin and segmental organization. Two distinct phases of development of the serotoninergic innervation were distinguished, that of the formation of the main axonal pathways and that of the branching of fibers. The development of main serotoninergic ascending pathways in dogfish was notably similar to that described in mammals. Our findings suggest the conservation of developmental patterns in serotoninergic systems and enhance the importance of elasmobranchs for understanding the early evolution of this system in vertebrates.
