CellLine#

lamindb provides access to the following public protein ontologies through bionty:

  1. Cell Line Ontology

Here we show how to access and search CellLine ontologies to standardize new data.

import bionty as bt
import pandas as pd
πŸ’‘ connected lamindb: testuser1/test-public-ontologies

PublicOntology objects#

Let us create a public ontology accessor with .public method, which chooses a default public ontology source from PublicSource. It’s a PublicOntology object, which you can think about as a public registry:

celllines = bt.CellLine.public(organism="all")
celllines
PublicOntology
Entity: CellLine
Organism: all
Source: clo, 2022-03-21
#terms: 39037

πŸ“– .df(): ontology reference table
πŸ”Ž .lookup(): autocompletion of terms
🎯 .search(): free text search of terms
βœ… .validate(): strictly validate values
🧐 .inspect(): full inspection of values
πŸ‘½ .standardize(): convert to standardized names
πŸͺœ .diff(): difference between two versions
πŸ”— .to_pronto(): Pronto.Ontology object

As for registries, you can export the ontology as a DataFrame:

df = celllines.df()
df.head()
name definition synonyms parents
ontology_id
CLO:0000000 cell line cell culturing a maintaining cell culture process that keeps ... None []
CLO:0000001 cell line cell A cultured cell that is part of a cell line - ... None []

CLO:0000003 adherent cell line culturing adherent cell line culturing is a cell line cu... None [CLO:0000000]
CLO:0000004 cell line cell modification a material processing that modifies an existin... None []

Unlike registries, you can also export it as a Pronto object via public.ontology.

Look up terms#

As for registries, terms can be looked up with auto-complete:

lookup = celllines.lookup()

The . accessor provides normalized terms (lower case, only contains alphanumeric characters and underscores):

lookup.hek293
CellLine(ontology_id='CLO:0001230', name='HEK293', definition=None, synonyms='293|HEK-293|293 HEK|293 cell|Human Embryonic Kidney 293|HEK 293', parents=array(['CLO:0037236'], dtype=object))

To look up the exact original strings, convert the lookup object to dict and use the [] accessor:

lookup_dict = lookup.dict()
lookup_dict["HEK293"]
CellLine(ontology_id='CLO:0001230', name='HEK293', definition=None, synonyms='293|HEK-293|293 HEK|293 cell|Human Embryonic Kidney 293|HEK 293', parents=array(['CLO:0037236'], dtype=object))

By default, the name field is used to generate lookup keys. You can specify another field to look up:

lookup = celllines.lookup(celllines.ontology_id)
lookup.clo_0000469
CellLine(ontology_id='CLO:0000469', name='immortal cat mixed endoderm/mesoderm-derived structure-derived cell line cell', definition='An immortal mixed endoderm/mesoderm-derived structure-derived cell line cell that derives from cat.', synonyms=None, parents=array(['CLO:0000213'], dtype=object))

Search terms#

Search behaves in the same way as it does for registries:

celllines.search("hek293").head(3)
ontology_id definition synonyms parents __ratio__
name
293-derived cell CLO:0037237 None 293|HEK-293|293 HEK|HEK293|HEK 293 [CLO:0037236] 100.000000

By default, search also covers synonyms:

celllines.search("Human Embryonic Kidney 293").head(3)
ontology_id definition synonyms parents __ratio__
name
HEK293 CLO:0001230 None 293|HEK-293|293 HEK|293 cell|Human Embryonic K... [CLO:0037236] 100.000000

HEK293T-derived cell CLO:0037373 None Human Embryonic Kidney 293T-derived cell [CLO:0037237] 78.787879

You can turn this off synonym by passing synonyms_field=None:

celllines.search("Human Embryonic Kidney 293", synonyms_field=None).head(3)
ontology_id definition synonyms parents __ratio__

Search another field (default is .name):

celllines.search(
    "suspension cell line",
    field=celllines.definition,
).head()
ontology_id name synonyms parents __ratio__
definition

Standardize CellLine identifiers#

Let us generate a DataFrame that stores a number of CellLine identifiers, some of which corrupted:

df_orig = pd.DataFrame(
    index=[
        "253D cell"
        "HEK293"
        "2C1H7 cell"
        "283TAg cell"
        "This cellline does not exist",
    ]
)
df_orig
253D cellHEK2932C1H7 cell283TAg cellThis cellline does not exist

We can check whether any of our values are validated against the ontology reference:

validated = celllines.validate(df_orig.index, celllines.name)
df_orig.index[~validated]
❗ 1 term (100.00%) is not validated: 253D cellHEK2932C1H7 cell283TAg cellThis cellline does not exist
Index(['253D cellHEK2932C1H7 cell283TAg cellThis cellline does not exist'], dtype='object')

Ontology source versions#

For any given entity, we can choose from a number of versions:

bt.PublicSource.filter(entity="CellLine").df()
uid entity organism currently_used source source_name version url md5 source_website created_at updated_at created_by_id
id

When instantiating a Bionty object, we can choose a source or version:

public_source = bt.PublicSource.filter(
    source="clo", version="2022-03-21", organism="all"
).one()
celllines= bt.CellLine.public(public_source=public_source)
