Bagnoli, Sara Drago, Davide Lorenzo Astoricchio, Emanuele Chiavacci, Elena Fronte, Baldassarre Cellerino, Alessandro Terzibasi Tozzini, Eva Animals Neurogenesis Neural Stem Cells Stem Cell Niche Skates, Fish Brain Telencephalon Neurons Mesencephalon Adult neurogenesis in cartilaginous fish remains a relatively unexplored area, particularly in terms of comparative analysis. This process, defined as the ability of specialized stem cells to generate new functional neurons, has gained prominence due to its relevance in neurodegenerative disease research and regenerative medicine. However, there is an ongoing discussion about when and where it first appeared. Evidence of adult neurogenesis in both teleosts and mammals highlights significant differences, such as the number of newly formed cells and the brain regions involved. Investigating additional cartilaginous fish species, which occupy a basal position in vertebrate phylogeny, could provide valuable insights into the ancient origins of this trait and potentially new general knowledge about the adult neurogenesis process. In this study, we combined immunohistochemistry and in situ hybridization to examine neurogenic activity in three brain regions-the telencephalon, mesencephalon, and cerebellum-of two batoid species: and . Immunohistochemical methods were used to identify neurogenic cells by employing markers for cell proliferation (PCNA), mitosis (pH3), glial cells (S100B), and stem cells (Msi1). Additionally, in situ hybridization was performed to detect neural stem cell mRNA for , , and in the telencephalon and mesencephalon of . |
