Le présent protocole décrit comment utiliser le rouge d’huile O pour colorer les gouttelettes lipidiques (LD), calculer la taille et le nombre de LD dans un modèle d’hépatocytes gras induits par des acides gras et utiliser BODIPY 493/503 pour observer le processus de fusion de petites LD en grandes LD par imagerie de cellules vivantes.

Nos recherches portent sur le nombre de gouttelettes lipidiques et la taille induite par l’acide linoléique dans les cellules hépatiques. De plus, nous visons à fournir des informations sur le mécanisme de la stéatose hépatique. Les progrès récents dans ce domaine de recherche, suggèrent que la choline, CCT alpha, autophagie induite établie, peut réguler la taille des gouttelettes lipidiques dans les cellules hépatiques bovines.

De plus, les observations de postes de travail de cellules vivantes ont montré que les phospholipides ont un effet considérable sur la fusion des gouttelettes lipidiques. Actuellement, l’aide génique, la pince à épiler à fluorescence, la chromatographie liquide, l’analyse omique, la chromatographie unique, la cytométrie en flux et d’autres technologies sont utilisées pour regrouper la vaste recherche dans ce domaine. La méthode expérimentale a certaines limites.
