Morphometric, stereological and citoarchitecture caracterization of the spinal cord posterior horn of the marmoset (Callithrix jacchus): A age and gender morphological study.
Callithrix jacchus, spinal cord, sterology, citoarchitecture
The white tufted marmoset (Callithrix jacchus) is a small primate native to Brazil and has been widely used in research models worldwide. The spinal cord of the tuff sagui has the main characteristics of a spinal cord typical of mammals. This similarity of the marrow to other primates and to humans, as well as the ease of management, short gestation and rapid colony formation, allow the marmosets to be increasingly used as alternative models of primates in biomedical research. Although we observe several studies associated with the nervous system of these primates, we have little information on possible morphological differences in the gray matter of the spinal cord of marmosets. Thus, this work aims to characterize the morphological differences between sexes and by age in the posterior gray column of the spinal cord of the sagui. Rexed neural slides will be analyzed through morphometric, stereological and cytoarchitectonic techniques, thus verifying the main differences between sex and age. The major neurochemical populations in the posterior column of these primates will also be characterized by immunohistochemistry. With the results of this research, we hope to contribute to the characterization of the posterior column of the spinal cord of the white tufted marmosets, differentiating by gender and age differences. In addition to providing background for future experimental studies related to gray matter and the posterior column of the spinal cord of tufted marmosets.
