CellMarker

lamindb provides access to the following public cell marker ontologies through bionty:

  1. CellMarker

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

import bionty as bt
import pandas as pd

PublicOntology objects

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

public = bt.CellMarker.public(organism="human")
public
 connected lamindb: testuser1/test-public-ontologies
PublicOntology
Entity: CellMarker
Organism: human
Source: cellmarker, 2.0
#terms: 15466

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

df = public.df()
df.head()
name synonyms gene_symbol ncbi_gene_id uniprotkb_id
0 A1BG A1BG 1 P04217
1 A2M A2M 3494 None
2 A2ML1 A2ML1 144568 A8K2U0
3 A4GALT A4GALT 53947 A0A0S2Z5J1
4 AADAC AADAC 13 P22760

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 = public.lookup()

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

lookup.immp1l
CellMarker(name='IMMP1L', synonyms='', gene_symbol='IMMP1L', ncbi_gene_id='196294', uniprotkb_id='Q96LU5')

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

lookup_dict = lookup.dict()
lookup_dict["IMMP1L"]
CellMarker(name='IMMP1L', synonyms='', gene_symbol='IMMP1L', ncbi_gene_id='196294', uniprotkb_id='Q96LU5')

Search terms

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

public.search("CD4").head(5)
name synonyms gene_symbol ncbi_gene_id uniprotkb_id
1900 Cd4 CD4 920 B4DT49
1901 CD40 CD40 958 A0A0S2Z3C7
1905 CD40LG CD40LG 959 P29965
1908 CD46 CD46 4179 P15529
1907 Cd44 CD44 960 P16070

Search another field (default is .name):

public.search("CD4", field=public.gene_symbol).head(1)
name synonyms gene_symbol ncbi_gene_id uniprotkb_id
1900 Cd4 CD4 920 B4DT49

Standardize cell marker identifiers

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

markers = pd.DataFrame(
    index=[
        "KI67",
        "CCR7",
        "CD14",
        "CD8",
        "CD45RA",
        "CD4",
        "CD3",
        "CD127a",
        "PD1",
        "Invalid-1",
        "Invalid-2",
        "CD66b",
        "Siglec8",
        "Time",
    ]
)

Now let’s check which cell markers can be found in the reference:

public.inspect(markers.index, public.name);
! 8 unique terms (57.10%) are not validated for name: 'KI67', 'CCR7', 'CD14', 'CD4', 'CD127a', 'Invalid-1', 'Invalid-2', 'Time'
   detected 4 unique terms with inconsistent casing/synonyms: KI67, CCR7, CD14, CD4
→  standardize terms via .standardize()

Logging suggests to map synonyms:

synonyms_mapper = public.standardize(markers.index, return_mapper=True)
synonyms_mapper
{'KI67': 'Ki67', 'CCR7': 'Ccr7', 'CD14': 'Cd14', 'CD4': 'Cd4'}

Let’s replace the synonyms with standardized names in the DataFrame:

markers.rename(index=synonyms_mapper, inplace=True)

The Time, Invalid-1 and Invalid-2 are non-marker channels which won’t be curated by cell marker:

public.inspect(markers.index, public.name);
! 4 unique terms (28.60%) are not validated for name: 'CD127a', 'Invalid-1', 'Invalid-2', 'Time'

We don’t find CD127a, let’s check in the lookup with auto-completion:

lookup = public.lookup()
lookup.cd127
CellMarker(name='CD127', synonyms='', gene_symbol='IL7R', ncbi_gene_id='3575', uniprotkb_id='P16871', _5='cd127')

It should be cd127, we had a typo there with cd127a:

curated_df = markers.rename(index={"CD127a": lookup.cd127.name})

Optionally, search:

public.search("CD127a").head()
name synonyms gene_symbol ncbi_gene_id uniprotkb_id __agg__

Now we see that all cell marker candidates validate:

public.validate(curated_df.index, public.name);
! 3 unique terms (21.40%) are not validated: 'Invalid-1', 'Invalid-2', 'Time'

Ontology source versions

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

bt.Source.filter(entity="bionty.CellMarker").df()
Hide code cell output
uid entity organism name in_db currently_used description url md5 source_website dataframe_artifact_id version run_id created_at created_by_id

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

source = bt.Source.get(name="cellmarker", version="2.0", organism="human")
public = bt.CellMarker.public(source=source)
public
PublicOntology
Entity: CellMarker
Organism: human
Source: cellmarker, 2.0
#terms: 15466

The currently used ontologies can be displayed using:

bt.Source.filter(currently_used=True).df()
