New LHC data on top quark p(T)-spectra obtained by the CMS Collaboration in pp collisions at root s = 7000 GeV are analyzed in the framework of z-scaling. The results are compared with Dempty set data on top quark differential cross section measurements at the Fermi lab Tevatron collider at root s = 1960 GeV. Flavour independence of the scaling function psi(z) observed in pp and p (p) over bar interactions over a wide collision energy range = 19-1960 GeV is verified. This property of psi(z) was found for different hadrons from pi-meson up to Upsilon particle. The flavour independence of psi(z) is used as indication on self-similarity of top quark production. A tendency to saturation of psi(z) at low z for the top quark is demonstrated.
