Figure 1 A general view of the culture dish with the needle. The magnetized acu-puncture needle is in the center. The needle passes through the cover of the outer dish (the “shirt”), then passes through the cover of the inner dish (the culture dish) and reaches the bottom of the culture dish. The needle is held in an upright position by both the “shirt” cover and the culture dish cover.
