Abstract
An algorithm is disclosed for computational modeling of stem-cell-driven tissue growth of adult spinal cord tissue. Simulations based on this model can be used for parameter testing and making predictions about the growth dynamics of biological spinal cord tissue. Such predictions include alterations in the growth dynamics and the final properties of the tissue induced by experimental or medical intervention.
