Korte visuele beschrijving van de chirurgische techniek en apparaat voor de levering van (gen en cellen) therapieën in het ruggenmerg. De techniek blijkt in het dier, maar is volledig en vertaalbaar momenteel gebruikt bij de mens.

Chirurgische Techniek voor Spinal Cord Levering van therapieën: Demonstratie van orde in Göttingen minivarkens

Source: Joshi, K., et al. Stereotaxic Surgical Approach to Microinject the Caudal Brainstem and Upper Cervical Spinal Cord via the Cisterna Magna in Mice. J. Vis. Exp. (2022)This video demonstrates the cisterna magna stereotaxic approach for targeted delivery to the brainstem and upper spinal cord. By accessing the cerebrospinal fluid-filled cisterna magna, this approach enables precise injections into areas that are difficult to reach using standard stereotaxic methods.

(2020)This video demonstrates the procedure of delivering an inducer drug into the cisterna magna of an anesthetized mouse. The injection selectively induces fluorescent marker expression in brain surface cells accessible via cerebrospinal fluid, confirmed by fluorescence imaging.

(2019)This video demonstrates the delivery of a test compound into the cerebrospinal fluid (CSF) through a catheter implanted in the lumbar spinal column of a rat model. The compound circulates along the CSF to the brain and spinal cord, enters neurons, and offers therapeutic potential.

Source: Li, D., et al. Direct Intrathecal Injection of Recombinant Adeno-associated Viruses in Adult Mice. J. Vis. Exp. (2019)This video demonstrates the procedure for the intrathecal injection of adeno-associated viruses (AAV) into the cerebrospinal fluid (CSF) of an awake mouse, covering syringe preparation, spinal alignment, and precise needle insertion. This method validates targeted gene delivery, supporting its potential for CNS therapies.

Intrathecal Delivery of Viruses in a Mouse Model for Treating Central Nervous System Diseases

Het doel van de huidige studie was het ontwikkelen en valideren van de kracht en de veiligheid van de lever-adeno-geassocieerde virus 9 (AAV9) -gemedieerde genafgifte door gebruik te maken van een nieuwe subpiale genafgifte techniek bij volwassen muizen.

Subpiaal Adeno-geassocieerde Virus 9 (AAV9) Vector Levering in Volwassene Muizen

Hier beschrijven we een methode voor het leveren van geneesmiddelen aan het centrale zenuwstelsel van de rat door het implanteren van een katheter in de lumbale intrathecale ruimte van de wervelkolom. We richten ons op de levering van antisense oligonucleotiden, hoewel deze methode ook geschikt is voor de levering van andere therapeutische modaliteiten.

Intrathecale afgifte van antisense oligonucleotiden in het centrale zenuwstelsel van de rat

Een chirurgische ingreep wordt beschreven om injecties uit te voeren in de lumbale stortbak van de jonge rat. Deze benadering is gebruikt voor de intrathecale toediening van gentherapievectoren, maar er wordt verwacht dat deze benadering kan worden gebruikt voor een verscheidenheid aan therapieën, waaronder cellen en medicijnen.

Intrathecale vectortoediening bij jonge ratten via lumbale stortbakinjectie

Hierin introduceren we een aangepaste methode voor intrathecale katheterisatie bij ratten die een eenvoudige, handige en betrouwbare benadering vertegenwoordigt voor herhaalde intrathecale toediening van geneesmiddelen.

Een aangepaste methode voor intrathecale katheterisatie bij ratten

Dit protocol beschrijft een chirurgische ingreep voor het uitvoeren van ruggenmergchirurgie en voor het implanteren en vastzetten van een optische schacht over het ruggenmerg bij knaagdieren.
