Intrathecal delivery of autologous culture-expanded adipose tissue-derived mesenchymal stem cells (AD-MSC) could be utilized to treat traumatic spinal cord injury (SCI). This Phase I trial (ClinicalTrials.gov: NCT03308565) included 10 patients with American Spinal Injury Association Impairment Scale (AIS) grade A or B at the time of injury. The study's primary outcome was the safety profile, as captured by the nature and frequency of adverse events. Secondary outcomes included changes in sensory and motor scores, imaging, cerebrospinal fluid markers, and somatosensory evoked potentials. The manufacturing and delivery of the regimen were successful for all patients. The most commonly reported adverse events were headache and musculoskeletal pain, observed in 8 patients. No serious AEs were observed. At final follow-up, seven patients demonstrated improvement in AIS grade from the time of injection. In conclusion, the study met the primary endpoint, demonstrating that AD-MSC harvesting and administration were well-tolerated in patients with traumatic SCI.

Introduction/purpose: Nusinersen, the first treatment approved for all spinal muscular atrophy (SMA) types, is administered intrathecally through lumbar puncture. We used ultrasound assistance or a landmark-based technique to access the lumbar intrathecal space in adult SMA patients. This study aimed to evaluate the technical success and adverse events (AEs) in such patients using either technique over a long observation period.

Background: We hypothesized that patients who received a lower dose of intrathecal morphine (ITM) would have higher postoperative opioid consumption following cesarean delivery.
Methods: Patients who had cesarean deliveries from February 15, 2022, through February 14, 2024 at Baylor Scott & White Medical Center - Temple with single injection spinal or combined spinal epidural anesthesia who did not have labor epidural anesthesia were included. Morphine milligram equivalent (MME) opioid consumption in the first 24 postoperative hours was recorded along with patient demographic, physical, and clinical characteristics.

The clinical use of small interfering RNA (siRNA) and antisense oligonucleotides often requires invasive routes of administration, including intrathecal or intraocular injection. Additionally, these treatments often necessitate repeated injections. While nanoparticle formulation and chemical modifications have extended siRNA therapeutic durability, challenges persist, such as the side effects of bolus injections with high toxicity and maximum exposure in the acute phase.

Introduction: Intrapleural injections of cholera toxin B conjugated to saporin (CTB-SAP) result in selective respiratory (, phrenic) motor neuron death and mimics aspects of motor neuron disease [(, amyotrophic lateral sclerosis (ALS) and spinal muscular atrophy (SMA)], such as breathing deficits. This rodent model allows us to study the impact motor neuron death has on the output of surviving phrenic motor neurons as well as the compensatory mechanisms that are recruited. Microglial density in the phrenic motor nucleus as well as cervical gene expression of markers associated with inflammation (.

Background: Effective clearance of lipid-rich debris by macrophages is critical for neural repair and regeneration after spinal cord injury (SCI). Interleukin-3 (IL-3) has been implicated in programming microglia to cluster and clear pathological aggregates in neurodegenerative disease. Yet, the influence of IL-3 on lipid debris clearance post-SCI is not well characterized.
