After the second experimental pig was completed, the data wasn't very encouraging; after all, there was no substantial improvement in the NK cells' ability to penetrate barriers, which is a difficult point in research. To treat tumors with NK cells, efforts must be concentrated in this area.
Scientific research is like this; when you encounter a problem, you analyze and solve it. To enhance the NK cells' ability to break through barriers, Professor Yang asked his team to start researching the tumor's barriers and which cells in the human body have the strongest ability to breach them. After obtaining complete data in this regard, the difficulty of NK cells penetrating barriers might be resolved.
Such matters can't be rushed. They can only be addressed gradually, advancing bit by bit, constantly adjusting the approach. As for success, that's currently not within the scope of consideration.
