Growth and development

[J Clark]

Hi David,

Yes I see what you mean.

Currently we have

[i]cellular physiological process
---[i]cell division
---[i]cell proliferation

cell division
def: The processes resulting in the physical partitioning 
and separation of a cell into daughter cells.

cell proliferation
def: The multiplication or reproduction of cells, resulting 
in the rapid expansion of a cell population.

This could become:

[i]cellular physiological process
---[i]cell proliferation
------[p]cell division


cell proliferation
def: The multiplication or reproduction of cells, occuring 
as a consequence of multiple cell division events, resulting 
in the expansion of a cell population.


That way we lose the word 'rapid', but keep the distinction 
between cell division and cell proliferation.

Would that seem like a plan? I'll post it in the sourceforge 
item.

Thanks,

Jen
