May 2008 Is a Orphans in the Cell Ontology
As of May 30, 2008, 57 cell types in the Cell Ontology lack an is_a path to the root node cell. We would like to provide this is_a path in short order. The proposal is to provide these paths by June 15, 2008, either by providing an is_a parent of an appropriate superclass of cell, or by linking to the root. We are taking suggestions about what is_a parents to use. Please look at the list below and make some suggestions. All cells still without a valid suggestion for an is_a path to the root will be made direct is_a children of the root node after June 15, 2008.
Please note that some of these cells do have a direct is_a parent but lack an is_a path to the root because their parent or grandparent has no is_a parent itself. In such cases correcting the parentage of a higher level cell type may correct the parentage of many lower level cell types as well.
