abstract = {The development of the human central nervous system is
accompanied by cell proliferation, differentiation and cell
death. The massive loss of neural cells during neurogenesis
suggests that apoptosis plays a critical role in human brain
development. To characterize apoptotic processes during
differentiation we analyzed the gene expression profiles of
proliferating versus differentiating ReNCell VM197 at six
different time points after induction of differentiation in
vitro. The expression levels of about 1,117 cDNA/ESTs
(expressed sequence tags) related to apoptosis pathways were
found to be changed at least 2-fold higher or lower in
differentiating cells than in proliferating cells.
Consistent with our previous Western/Immunoblotting studies,
we observed that pro-apoptotic proteins like Bax, Bid and
cytochrome c showed increased gene expression during the
first 6 h of differentiation and diminished expression
levels at later stages of differentiation. In contrast the
gene and protein expression levels of the anti-apoptotic
protein Bcl-2 was found to be increased 6 h and 12 h
respectively post-initiation of differentiation. We conclude
that both, pro-apoptotic and anti-apoptotic processes occur
during differentiation of VM197 cells and that Bcl-2 plays a
protective role against apoptosis in fully differentiated
neurons.},
