Stem cells isolated from the CNS of both embryonic and adult mice can generate neurons and glia through the activation of different patterns of differentiation in dependence of exposure to appropriate epigenetic signals. On the other hand, environmental conditions might affect the proliferation, migration and differentiation of these cells. We report here, for the first time, that inorganic mercury affects the proliferative and differentiative capacity of adult neuronal stem cells (ANSC). Actually, inorganic mercury increases apoptosis in ASNC. Furthermore, in stem cell-derived astrocytes, high levels of HSP-70 occur, while the levels of GTP-b tubulin activity dramatically decrease. Interestingly, when induced to differentiate, inorganic mercury modifies morphological proprieties of astrocytes, while the neuron population is reduced. These results demonstrate that inorganic mercury produces toxicity in the ANSC-derived neuronal population and affects the biological properties of the glial-derived population.

Keywords: neuronal stem cell; inorganic mercury; HSP-70.

A manuscript entitled "Mitochondrial mediated thimerosal-induced apoptosis in a human neuroblastoma cell line (SK-N-SH) A potential proapoptotic role for nuclear factor kappa binding protein (NFkB)" based in part on this work is currently being prepared by Dr. Kiningham for submission to a peer reviewed journal.
