Sprague–Dawley male rats, fed with a tryptophan-deficient and 8% protein corn-based diet
were compared with a group of animals fed with 8% protein alone, and with a group fed with
Chow Purina containing 23% protein. Retardation of Bergmann glial cell maturation and a
concomitant retardation in granule cell migration were observed in the corn-fed group at 21
days. At 30 days of age, the dendrites of granule cells of both hypoproteic and corn-fed
groups were larger than those of the Chow-fed animals. At 60 days of age, dendritic …
