The intra-arterial (IA) model by microcatheter administration was an effective way to deliver drugs or cells to the brain. All of these models were carried out introduced in rat rather than mice for the difficult and technically challenging due to their small caliber. In 2014, Alejandro Santillan first introduced this model in mice and we found that most of the operational steps were similar with the middle cerebral artery occlusion and reperfusion (MCAO/R) model. We attempted to combine these two techniques into a single model in mice and discovered that this technique was indeed possible. In our work, 12C57B1/6J male mice were carried on middle cerebral artery occlusion for 60 min and then the intra-arterial microcatheter was placed into the internal carotid artery (ICA) from the external carotid artery (ECA). GFP-Luc-Pro labeled mNSCs were infused through the microcatheter and then the blood flow perfusion was reestablished subsequently. The results showed that all 12 mice were carried on successfully the model of middle cerebral artery occlusion, and the placement of the microcatheter and the mNSCs perfusion were completed smoothly without exception. Which means that it is logical to combine the two models into one in order to facilitate studying of stroke. Meanwhile, during the dissection, we found the variation of occipital artery (OA) was noticeable and we classified first time this variation into four categories to attempt to protect the OA.
