Hello all,

Here is my cell type node (anatomy and definition file). So far, 70 terms,
with definitions mostly from K Esau. Please take a look, if it's good (as
I believe so), I'll import it to the anatomy ontology. IDs are temporary,
all the terms will have proper PO ID numbers once I import this node to
PO file.

Pankaj and Felipe, thanks for the earlier comments. Please, delete the old
version, this one has more hierarchy.

A short question: Are epithem cell and epithelium cell children of
secretory cell?

Katica
