Cytoarchitecture of the Spinal Cord of the Postnatal (P4) Mouse

Abstract: Interpretation of the new wealth of gene expression and molecular mechanisms in the developing mouse spinal cord requires an accurate anatomical base on which data can be mapped. Therefore, we have assembled a spinal cord atlas of the P4 mouse to facilitate direct comparison with the adult specimens and to contribute to studies of the development of the mouse spinal cord. This study presents the anatomy of the spinal cord of the P4 C57Bl/6J mouse using Nissl and acetyl cholinesterase-stained sections. It inclu… Show more

“…To quantify distributions of premotor neurons, we selected a single muscle, the ankle extensor gastrocnemius, and analyzed its premotor circuitry by regional and laminar distribution 17 . 52% of all rabies virus–labeled pregastrocnemius spinal neurons were located in the medial deep dorsal horn (laminae V–VI), compared with 28% in the ipsilateral ventral horn (laminae VII–IX), 7% in the contralateral spinal cord, 4% in the superficial dorsal horn (laminae I–IV) and 3% in the lateral deep dorsal horn (laminae V–VI) ( n = 4,594 cells in 20 spinal cords; Fig.…”

“…Theoretical models indicate that the static gradient diffusion measurement provided a window on membrane structures smaller than roughly 1400 nm. The neonatal mouse spinal cord contains mostly gray matter (79,80). Structures smaller than 1400 nm include cells and portions of cells with small radii such as axons, dendrites, glial processes, myelin, and a number of membranous organelles such as nuclei, mitochondria, endoplasmic reticula, and vesicles (81), in addition to extracellular sheets and tunnels (82).…”
