  In this work we upscale a prototypical kinetic transport equation which
models a cell population moving in a fibrous environment with a chemo- or
haptotactic signal influencing both the direction and the magnitude of the cell
velocity. The presented approach to scaling does not rely on orthogonality and
treats parabolic and hyperbolic scalings in a unified manner. It is shown that
the steps of the formal limit procedures are mirrored by rigorous operations
with finite measures provided that the measure-valued position-direction fiber
distribution enjoys some spacial continuity.
