Les cellules souches neurales récoltés dans le cerveau adulte sont de plus en plus utilisés dans des applications allant de la recherche fondamentale du développement du système nerveux à l'exploration des applications cliniques potentielles en médecine régénérative. Cela rend le contrôle rigoureux des conditions d'isolement et de culture utilisés pour cultiver ces cellules essentielles au son des résultats expérimentaux.

L’objectif global de l’expérience suivante est de générer des cultures de cellules souches neurales à partir de différentes zones du cerveau des rongeurs adultes. Ceci est réalisé en prélevant du tissu dans une région d’intérêt pour examiner la présence et le potentiel de cellules souches neurales. Dans un deuxième temps, transformez le tissu en une suspension cellulaire pour le placage en tant que culture monocouche.

Ensuite, utilisez des conditions de culture définies pour propager sélectivement les cellules souches neurales, validant ainsi leur potentiel d’auto-renouvellement. Des résultats in vitro sont obtenus montrant que les cellules souches neurales sont multipotentes en fonction de leur potentiel de différenciation, et comment divers facteurs peuvent influencer leur auto-renouvellement et leur destin. Cette méthode peut aider à répondre à des questions clés dans les domaines des neurosciences et de la médecine régénérative, telles que l’emplacement des cellules souches neurologiques endogènes et la façon de les manipuler.
