Fat proposed new cell ontology terms

[olgabot]

Hello! This discussion is to propose the free_annotation terms to the Cell Ontology so that future researchers may use your specific terms rather than the generic ones that you had to use. Below are your free_annotation terms and what I (@olgabot) thought the relationship was to the existing cell ontology term, whether it was brand new term and cell type, in which case I used is_a, or it was merely a synonym for a term that already existed in the cell ontology, in which case I used synonym.

Please comment below with what is the correct relationship between terms, or correct the term itself and I'll deal with the submission to the Cell Ontology group.

Thank you for your help! Warmest, Olga

For the annotations below, here is the format:

• [ ] free annotation relationship cell ontology class

Relationships could be either:

• is_a - means that the free annotation label is a new "cell type" to add to the cell ontology
• synonym - means that the free annotation label is not a new cell type, but another term for the same thing that already exists in the cell ontology

I wasn't always sure which relationship to use so please comment below and I will correct it.

Examples:

• [ ] Inhibitory neuron is_a neuron
• [ ] alveolar epithelial type 2 cells synonym type II pneumocyte

FACS

• [ ] mesenchymal progenitor synonym mesenchymal stem cell of adipose

I think synonym, but let's check with Mike in case there is some subtle difference in meaning among those in the adipose field

There's a bit of ambiguity here, but I'd leave it as a synonym. Thanks!

Great! Can you point to a few publications which use mesenchymal progenitor as a synonym for mesenchymal stem cell of adipose?
