The development of in vitro microtubule assembly and of tubulin concentration have been studied during brain maturation in the mouse and the rat, two species which have postnatal brain development, and in one species which is mature at birth, the guinea pig. (a) The rat of tubulin assembly is very slow soon after birth in both the mouse and rat; it increases progressively with age until adulthood. In contrast, in the guinea pig this rate is maximal at birth and slower rates are seen only at foetal stages. (b) Postnatal changes in the lag period of assembly and in the minimal concentration of tubulin (Cc) required to obtain in vitro assembly are seen in the mouse and the rat; in contrast these parameters are constant at all postnatal stages in the guinea pig with longer lag periods and lower Cc values being seen only at foetal stages. (c) Maximal rates of assembly, minimal lag periods, and minimal Cc values are restored after addition of microtubule-associated proteins to foetal guinea pig or young mouse and rat preparations, suggesting that the difference in the kinetic parameters of assembly between these species depends on differences in the concentration or activity of these proteins. (d) Maximal tubulin concentrations are observed before birth in the guinea pig and approximately at day 10 in the rat and mouse.
