A Mathematical Model of Regenerative Axon Growing along Glial Scar after Spinal Cord Injury

Figure 3

Longitudinal sections for three-dimensional concentration field of Type 1 factors. The concentration of the dark blue area equals zero and the red area represents the highest concentration. The target cells were located in two red circular domains nearby the top of glial scar. (a, c, e) The horizontal half axle of number 1, number 3, and number 5 remains constant at a value of and their vertical half axle increases from to (increasing each time). (b, c, d) The vertical half axle of number 2, number 3, and number 4 remains constant at a value of and their transverse radius increases from to (increasing each time).

(a) Number 1
