CellType#

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

  1. Cell Ontology

Here we show how to access and search CellType 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:

celltypes = bt.CellType.public(organism="all")
celltypes
PublicOntology
Entity: CellType
Organism: all
Source: cl, 2023-08-24
#terms: 2894

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 = celltypes.df()
df.head()

ontology_id

CL:0000004 obsolete cell by organism Obsolete: A Classification Of Cells By The Org... 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 = celltypes.lookup()

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

lookup.cd8_positive_alpha_beta_t_cell
CellType(ontology_id='CL:0000625', name='CD8-positive, alpha-beta T cell', definition='A T Cell Expressing An Alpha-Beta T Cell Receptor And The Cd8 Coreceptor.', synonyms='CD8-positive, alpha-beta T-cell|CD8-positive, alpha-beta T lymphocyte|CD8-positive, alpha-beta T-lymphocyte', parents=array(['CL:0000791'], 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["CD8-positive, alpha-beta T cell"]
CellType(ontology_id='CL:0000625', name='CD8-positive, alpha-beta T cell', definition='A T Cell Expressing An Alpha-Beta T Cell Receptor And The Cd8 Coreceptor.', synonyms='CD8-positive, alpha-beta T-cell|CD8-positive, alpha-beta T lymphocyte|CD8-positive, alpha-beta T-lymphocyte', parents=array(['CL:0000791'], dtype=object))

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

lookup = celltypes.lookup(celltypes.ontology_id)
lookup.cl_0000625
CellType(ontology_id='CL:0000625', name='CD8-positive, alpha-beta T cell', definition='A T Cell Expressing An Alpha-Beta T Cell Receptor And The Cd8 Coreceptor.', synonyms='CD8-positive, alpha-beta T-cell|CD8-positive, alpha-beta T lymphocyte|CD8-positive, alpha-beta T-lymphocyte', parents=array(['CL:0000791'], dtype=object))

Search terms#

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

celltypes.search("CD8 positive T cell").head(3)
ontology_id definition synonyms parents __ratio__
name
Tc1 cell CL:0000917 A Cd8-Positive, Alpha-Beta Positive T Cell Tha... Tc1 T lymphocyte|Tc1 T-cell|Tc1 T cell|T-cytot... [CL:0000908] 95.000000

By default, search also covers synonyms:

celltypes.search("Tc1 T lymphocyte").head(3)
ontology_id definition synonyms parents __ratio__
name
Tc1 cell CL:0000917 A Cd8-Positive, Alpha-Beta Positive T Cell Tha... Tc1 T lymphocyte|Tc1 T-cell|Tc1 T cell|T-cytot... [CL:0000908] 100.000000

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

celltypes.search("Tc1 T lymphocyte", synonyms_field=None).head(3)
ontology_id definition synonyms parents __ratio__
name

Peyer's patch lymphocyte CL:0009014 A Lymphocyte That Is Part Of A Peyer'S Patch. ... Peyer's patch resident lymphocyte [CL:0000542] 65.000000

Search another field (default is .name):

celltypes.search(
    "CD8 positive alpha beta T cell",
    field=celltypes.definition,
).head()
ontology_id name synonyms parents __ratio__

Standardize CellType identifiers#

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

df_orig = pd.DataFrame(
    index=[
        "Boettcher cell"
        "bone marrow cell"
        "interstitial cell of ovary"
        "pancreatic ductal cell"
        "This celltype does not exist",
    ]
)
df_orig
Boettcher cellbone marrow cellinterstitial cell of ovarypancreatic ductal cellThis celltype does not exist

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

validated = celltypes.validate(df_orig.index, celltypes.name)
df_orig.index[~validated]
❗ 1 term (100.00%) is not validated: Boettcher cellbone marrow cellinterstitial cell of ovarypancreatic ductal cellThis celltype does not exist
Index(['Boettcher cellbone marrow cellinterstitial cell of ovarypancreatic ductal cellThis celltype does not exist'], dtype='object')

Ontology source versions#

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

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

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

public_source = bt.PublicSource.filter(
    source="cl", version="2023-04-20", organism="all"
).one()
celltypes= bt.CellType.public(public_source=public_source)
