Multicellular development requires that the basic processes of cell growth and proliferation be subjugated to a higher level ontogenetic program.
As a model of neural development, we employed primary fetal human neural progenitor cells (hNPCs), which are cultured as neurospheres and mimic basic processes of brain development in vitro: proliferation, migration, and differentiation.
These three-dimensional cell systems mirror basic processes of fetal brain development such as proliferation, migration, differentiation, and apoptosis.
A better knowledge of the mechanisms that stand beyond a correct transmission of mitochondrial genetic information would greatly help the understanding of basic processes of cellular life, such as ageing, cell proliferation, cell differentiation, and gamete competence.
IL-7 participates in a coordination of the basic processes of early thymocyte development, namely, survival (through Bcl-2 upregulation), proliferation, and TCR rearrangement.
The MMPs are implicated in basic processes of tumour progression, such as degradation of basement membrane and extracellular matrix, stimulation of cellular proliferation, cellular motility, resistance to apoptosis and angiogenesis.
Therefore, we established and characterized this three-dimensional human neurosphere system that imitates the basic processes of brain development proliferation, differentiation, and migration [ Figure 2; see also Supplemental Material, Figures 1 and 2 (available at http://www.ehponline.org/members/2009/0800207/suppl.pdf)].
This questionnaire measures 10 basic processes of change.

The basic process of CEPGA is showed in the figure.
