Spinal Cords, Cervical

Spinal Cords, Cervical: The upper portion of the spinal cord located within the cervical vertebrae.
The cervical spinal cord contains nerve fibers that transmit sensory and motor information to and from the brain, controlling vital functions like respiration, heart rate, and blood pressure.
This region is crucial for maintaining proper neurological function and is a common target for injury or disease.
Researchers can leverage PubCompare.ai to streamline their studies on cervical spinal cords, optimizing research protocols and boosting reproducibility through AI-driven comparisons of the latest literature, pre-prints, and patents.

In preparation for the dorsal column section of the spinal cord, each monkey was initially anesthetized with ketamine hydrochloride (15mg/kg, i.m.) and then maintained in a stereotaxic head holder at a surgical level of anesthesia with 1-3% isoflurane. The depth of anesthesia was monitored by recording the heart and respiration rates, and testing for withdrawal reflexes. Rectal body temperature was maintained at 37-38°C. Under aseptic conditions, a portion of the cervical spinal cord was exposed, and the dorsal columns were sectioned on one side with a pair of fine surgical scissors at cervical level C4-C6. Dura was replaced with Gelfilm and covered with Gelfoam. The opening was closed, and the skin sutured. The monkeys were carefully monitored until they were fully recovered from anesthesia and then returned to their home cage. Monkeys received antibiotics and analgesics for 2-3 days after surgery. Animals’ cage behavior and food intake typically returned to normal shortly after surgery. Further details about surgical procedures can be found in previous publications from the laboratory (Jain et al., 1997 (link); 2008 (link)).

Neuropathologic analysis for cases #1–6 (Table 1) was performed according to the standardized procedures of the Center for Neurodegenerative Disease Research (CNDR) Brain Bank at the University of Pennsylvania as previously described [33 (link)]. Case #7 was obtained from the archives of the Hospital of the University of Pennsylvania and was largely processed in the same fashion except for a longer fixation period (~2 weeks). Briefly, brain and spinal cord regions were fixed in neutral buffered formalin, and 6 μm thick sections were cut from paraffin-embedded tissue. CNS tissue samples were obtained from the following regions for study here: mid-frontal cortex, primary motor cortex, superior and middle temporal cortex, parietal cortex (angular gyrus), occipital (primary visual) cortex, anterior cingulate gyrus, amygdala with parahippocampal gyrus, striatum and globus pallidus, mid-thalamus, hippocampus with parahippocampal gyrus, cerebellum including dentate nucleus, midbrain including substantia nigra, pons including locus ceruleus, medulla including inferior olive, and cervical spinal cord.
Closely adjacent series of sections from each CNS region were stained with hematoxylin and eosin or by immunohistochemistry using standard avidin–biotin complex methods with microwave antigen retrieval in citrate buffer. Antibodies included anti-TDP-43 antibodies (rat monoclonal TAR5P-1D3 (pS409/410 TDP-43) Ascenion, Munich, Germany [26 (link)]; 6H6E12, ProteinTech, Chicago, IL; 5104, 5095 and C1039, CNDR [18 (link)]), anti-ubiquitin (MAB1510, Chemicon, Temecula, CA, USA), anti-Aβ (NAB228, CNDR [19 (link), 20 (link)]), anti-phosphorylated tau (PHF1, gift of Professor Peter Davies, Albert Einstein College of Medicine, New York, NY, USA), and anti-α-synuclein (SYN303, CNDR [11 (link)]). Antibody concentration optimization was sometimes required to enhance visualization of TDP-43 pathology.
Additional FTLD-TDP cases with documentation of age of onset, age of death, and FTLD-TDP subtype were identified in the CNDR Integrated Neurodegenerative Disease Database (INDD) as described [33 (link)]. 102 cases were identified corresponding to 38 type A, 34 type B, and 30 type C cases.

70 μm sections were independently examined by experienced
investigators (JB, DJI) and graded on a standard validated ordinal scale (i.e.
0=none/rare, 1=mild, 2=moderate,
3=severe)10 (link), 15 (link), 25 (link) for the burden of tau deposition and neuronal loss in
the following regions: amygdala (AMY), hippocampus (HIPP), orbitofrontal cortex
(OFC), mid-frontal cortex (MFC), anterior cingulate gyrus (ACG),
superior/mid-temporal gyri (SMT), primary motor cortex (MOT), angular gyrus
(ANG), primary sensory cortex (SENS), primary visual cortex (VIS), caudate
nucleus and putamen (striatum STR), globus pallidus (GP), thalamus (THAL),
midbrain, pons, medulla (MED), cerebellum (CB) and cervical spinal cord (CSC).
Anatomic regions/nuclei within these sections examined included: the cornu
ammonis/subiculum (CA), entorhinal cortex (ERC) and dentate gyrus (DG) in HIPP;
substantia nigra (MBSN) and red nucleus (MBRN) in midbrain; locus coeruleus (LC)
and raphe nuclei (RPN) in the pons; hypoglossal nucleus (MEDXII), dorsal motor
nucleus of the vagus (MEDX), reticular formation (MEDRF), inferior olive
(MEDIO), and arcuate nucleus and pontobulbar body pre-cerebellar nuclei (MED
ARC/PB); dentate nucleus (CBDG) and granular layer (CBGL) of the cerebellum.
Discrepant scores were re-reviewed by both examiners and consensus scores were
reached. Sections were also separately graded for the severity of ramified
astrocytes and tau pathology in adjacent white matter (WM). Finally, since PiD
can preferentially affect specific cortical lamina (i.e. II, VI) 26 , cortical sections were also
examined for tau deposition in superficial cortical layers (layers II-III) and
deep cortical layers (V-VI). Hypothetical phases of sequential tau deposition
were constructed through comparison of regional involvement for AT-8 staining in
70 μm thick sections.
A subset of regions (AMY, ERC, DG, CA, MFC, OFC, ACG, SMT, ANG, SENS,
STR, MOT, VIS) were selected for 6 μm section IHC experiments for UBQ,
ThS, Tau C3, RD4 and anti-4R tau and graded on a similar ordinal scale.

Example 3

Alternatively or in addition to all of the foregoing as it relates to gray matter, the invention further contemplates that white matter fA (fractional anisotropy) can be employed in a manner analogous to the gray matter atrophy as discussed herein in various embodiments.

Diffusion Tensor Imaging (DTI) assesses white matter, specifically white matter tract integrity. A decrease in fA can occur with either demyelination or with axonal damage or both. One can assess white matter substructures including optic nerve and cervical spinal cord.

MRIs of brain including high cervical spinal cord to be done at month 6, 1 year, and 2 years. If a decrease in fA of 10% is observed in fA of 2 tracts, treat with estriol to halt this decrease. Alternatively if fA is decreased by 10% in only one tract but that tract is associated with clinical deterioration of the disability served by that tract, treat with estriol. Poorer scores in low contrast visual acuity would correlate with decreased fA of optic nerve, while poorer motor function would correlate with decreased fA in motor tracts in cervical spinal cord.

The cervical spinal cord was exposed by laminectomy as previously described [38 ]. Briefly, animals were intubated by insertion of a canula in the trachea providing oxygen and isoflurane through a Minivent system (Harvard apparatus). Laminectomy (C2-5) was performed and spinal column fixed at C1 and C6 in a stereotactic frame. Body temperature and heart rate were recorded and stored electronically. Imaging was performed via 2-photon (LaVision TrimScope II microscope, Spectra-Physics laser). Mouse respiration via MiniVent was synchronized to picture acquisition through a triggering device (TrigViFo) reducing imaging artifacts [97 ]. Through an additional toolkit (VivoFollow II) [97 ], this synchronization allowed real-time distortion correction. Tissue displacement was automatically corrected by objective and stage adjustment through a Python script (VivoFollow I) [96 (link)]. Single images, z-stacks and videos were acquired with ImSpector software (LaVision). Raw images were processed with Fiji [82 (link)] and saved as TIF.

An autopsy restricted to the brain (including a small portion of cervical spinal cord) was performed on subject BI. The brain was extensively sampled according to the UCLA dementia protocol including representative sections from the frontal, temporal, parietal and occipital cortices, hippocampus, entorhinal cortex, amygdala, basal ganglia, brainstem and cerebellum. Six-micrometre sections were cut from formalin-fixed paraffin-embedded tissue and were stained with haematoxylin and eosin. Several blocks were also stained with Luxol fast blue. Immunohistochemistry was implemented with antibodies to β-amyloid 1–42 (1:150, EMD Millipore, rabbit polyclonal, AB5078P), β-amyloid 1–40 (1:400, EMD Millipore, rabbit polyclonal, AB5074P), phospho-tau (1:200, Thermo Fisher, mouse monoclonal, AT8) and alpha-synuclein (1:450, EMD Millipore, rabbit polyclonal, AB5038). Incubation with primary antibodies was followed by either horse anti-mouse or horse anti-rabbit secondary antibody conjugated to horseradish peroxidase (MP7402 & MP7401; Vector Laboratories, Burlingame, CA, USA). Visualization of antibody reactivity was achieved with NN-diaminobenzidine as chromogen (no. SK-4100; Vector Laboratories) and then counterstained with haematoxylin. Neuropathologic substrates of dementia were assessed using standard diagnostic criteria.19 (link) The presence of cerebrovascular disease was also evaluated, including cerebral amyloid angiopathy (CAA) graded according to the Vonsattel criteria.20 (link)All three participants with the F388S mutation, 5/8 of the A431E mutation carriers and 2/3 carriers of PSEN1 mutations not causing SP were male. We therefore were unable to assess effects of gender.

In situ hybridization and immunohistochemistry was performed as previously described (Philippidou et al., 2012 (link); Vagnozzi et al., 2020 (link)), on tissue fixed for 2 h in 4% paraformaldehyde (PFA) and cryosectioned at 16 μm. In situ probes were generated from e12.5 cervical spinal cord cDNA libraries using PCR primers with a T7 RNA polymerase promoter sequence at the 5’ end of the reverse primer. All probes generated were 750–1000 bp in length. Wholemounts of diaphragm muscles were stained as described (Philippidou et al., 2012 (link)). The following antibodies were used: rabbit anti-cleaved Caspase 3 (1:1000; Cell Signaling, RRID:AB_2341188), mouse anti-olig2-A488-conjugated (1:500; Millipore, RRID:AB_11205039), rabbit anti-β-Catenin (1:250; Cell Signaling Technology, RRID:AB_11127203), goat anti-Scip (1:5000; Santa Cruz Biotechnology, RRID:AB_2268536), mouse anti-Islet1/2 (1:1000, DSHB, RRID:AB_2314683) (Tsuchida et al., 1994 (link)), rabbit anti-neurofilament (1:1000; Synaptic Systems, RRID:AB_887743), rabbit anti-synaptophysin (1:250, Thermo Fisher, RRID:AB_10983675), and α-bungarotoxin Alexa Fluor 555 conjugate (1:1000; Invitrogen, RRID:AB_2617152). Images were obtained with a Zeiss LSM 800 confocal microscope and analyzed with Zen Blue, ImageJ (Fiji), and Imaris (Bitplane). Phrenic MN number was quantified using the Imaris “spots” function to detect cell bodies that coexpressed high levels of Scip and Isl1/2 in a region of interest limited to the left and right sides of the ventral spinal cord.
