The course of putrescine immunocytochemical appearance in neurons, astroglia and microglia in rat brain cultures.


Putrescine, the diamine precursor for polyamine biosynthesis, is a ubiquitous molecule normally present at low concentration in quiescent cells. During development, or after traumatic stress, putrescine concentrations are greatly increased. Here we describe the localization of putrescine by fluorescence immunocytochemistry in primary cultures of embryonic… (More)
