CD BioSciences is committed to developing high-resolution three-dimensional (3D) technologies to help clients capture local and global structural changes in neuronal morphology. We offer imaging, digitization and analysis of neuronal morphology to investigate the structural basis of impaired neurotransmission and plasticity, so as to reveal the mechanism of cognitive decline in normal aging and neurodegenerative diseases.
Cognitive impairment in normal aging and neurodegenerative diseases is accompanied by morphological changes on multiple scales, from the fine-grained geometry of individual neurons, dendrites, and spines to the spatial complexity of multi-neuron and vascular networks in the presence of space-occupying histopathologic lesions. Understanding the mechanisms by which these structural changes lead to the observed cognitive deficits requires accurate 3D morphometry, as well as realistic physical models that can reliably represent both global dendritic structure and detailed spine geometry.
While the gross morphological effects of the neurodegenerative disease have been well documented by stereological methods, alterations in the morphology of fine-grained single neurons and the overall topology of multi-neuron and vascular networks remain poorly characterized. These more complex morphological changes and their interactions are critical to understanding the spatial and temporal progression of neurodegenerative diseases. The development of automated systems for digitization, 3D reconstruction and geometric analysis of accurate and detailed cellular and tissue morphology is therefore critical to understanding the etiology of impaired cognitive function.
