  We consider a system of two kinetic equations modelling a multicellular
system : The first equation governs the dynamics of cells, whereas the second
kinetic equation governs the dynamics of the chemoattractant. For this system,
we first prove the existence of global-in-time solution. The proof of existence
relies on a fixed point procedure after establishing some a priori estimates.
Then, we investigate the hyperbolic limit after rescaling of the kinetic
system. It leads to a macroscopic system of Cattaneo type. The rigorous
derivation is established thanks to a compactness method.
