Mm. Romeroaleman et al., DEVELOPMENT OF ASTROGLIAL CELLS IN THE ENCEPHALON OF GALLOTIA-GALLOTI- A GOLGI TECHNIQUE STUDY, Journal of morphology, 223(1), 1995, pp. 13-20
Some variants of the Golgi techniques have been used to study the poss
ible origin and developmental sequence of astroglial cells in the liza
rd Gallotia galloti. The developmental sequence consists of progressiv
e transformations of astroglial cells originating either from radial g
lia or from glioblasts. The so-called displaced radial glia, an interm
ediate cellular type between radial glia and astrocytes, indicate the
radial glia/astrocytes transformation. Apparently, glioblasts also evo
lve into astroblasts that, in turn could develop into immature protopl
asmic or fibrous astrocytes, precursors of mature protoplasmic and fib
rous astrocytes, respectively. The present study confirms our previous
ultrastructural and immunohistochemical studies on the same animal. (
