CellType

lamindb provides access to the following public CellType 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

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, 2024-02-13
#terms: 2918

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

df = celltypes.df()
df.head()
name definition synonyms parents
ontology_id

CL:0000003 obsolete native cell Obsolete. A Cell That Is Found In A Natural Se... None []
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
Tc2 cell CL:0000918 A Cd8-Positive, Alpha-Beta Positive T Cell Exp... T-cytotoxic T cell type 2|Tc2 T-lymphocyte|Tc2... [CL:0000908, CL:0001052] 95.000000

By default, search also covers synonyms:

celltypes.search("Tc1 T lymphocyte").head(3)
ontology_id definition synonyms parents __ratio__
name

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__

Search another field (default is .name):

celltypes.search(

    field=celltypes.definition,
).head()

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 cell
bone marrow cell
interstitial cell of ovary
pancreatic ductal cell
This 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 (20.00%) is not validated: This celltype does not exist

Index(['This 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 run_id created_by_id updated_at
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)
celltypes
