How to program the change of Young's modulus depending on the former element

Hello,
Now I want to simulate the change Young's modulus due to the mechanical stimulus in soft tissue. In our soft tissue(scaffold) we have seeded living cells and these cells produce the collagen fiber type-II which could be interpreted as change of Young's modulus. The Young's modulus of neighbour elements of the cells have to change depending on the Young's modulus of former elements like domino.
I have two constitutitve equations programmed in UMAT i. e. for scaffold and for fibers and they run good.
