Cell marker#
lamindb provides access to the following public cell marker ontologies through bionty:
Here we show how to access and search cell marker ontologies to standardize new data.
import bionty as bt
import pandas as pd
💡 connected lamindb: testuser1/test-public-ontologies
PublicOntology objects#
Let us create a public ontology accessor with public(), which chooses a default public ontology source from PublicSource. It’s a PublicOntology object, which you can think about as a public registry:
public = bt.CellMarker.public(organism="human")
public
PublicOntology
Entity: CellMarker
Organism: human
Source: cellmarker, 2.0
#terms: 15466
📖 .df(): ontology reference table
🔎 .lookup(): autocompletion of terms
🎯 .search(): free text search of terms
✅ .validate(): strictly validate values
🧐 .inspect(): full inspection of values
👽 .standardize(): convert to standardized names
🪜 .diff(): difference between two versions
🔗 .to_pronto(): Pronto.Ontology object
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)
| synonyms | gene_symbol | ncbi_gene_id | uniprotkb_id | __ratio__ | |
|---|---|---|---|---|---|
| name | |||||
| Cd4 | CD4 | 920 | B4DT49 | 100.0 | |
| CD4+ | None | None | None | 100.0 | |
| CD45RB | None | None | None | 90.0 | |
| CD45RO | None | None | None | 90.0 | |
| CD44R | None | None | None | 90.0 |
Search another field (default is .name):
public.search("CD4", field=public.gene_symbol).head(1)
| name | synonyms | ncbi_gene_id | uniprotkb_id | __ratio__ | |
|---|---|---|---|---|---|
| gene_symbol | |||||
| CD4 | Cd4 | 920 | B4DT49 | 100.0 |
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);
✅ 6 terms (42.90%) are validated for name
❗ 8 terms (57.10%) are not validated for name: KI67, CCR7, CD14, CD4, CD127a, Invalid-1, Invalid-2, Time
detected 4 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
💡 standardized 10/14 terms
{'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);
✅ 10 terms (71.40%) are validated for name
❗ 4 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()
| synonyms | gene_symbol | ncbi_gene_id | uniprotkb_id | __agg__ | __ratio__ | |
|---|---|---|---|---|---|---|
| name | ||||||
| CD127 | IL7R | 3575 | P16871 | cd127 | 90.909091 | |
| CD1 | CD1A | 910 | P29016 | cd1 | 90.000000 | |
| CD172a | None | None | None | cd172a | 83.333333 | |
| CD167a | None | None | None | cd167a | 83.333333 | |
| CD121a | None | None | None | cd121a | 83.333333 |
Now we see that all cell marker candidates validate:
public.validate(curated_df.index, public.name);
✅ 11 terms (78.60%) are validated
❗ 3 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.PublicSource.filter(entity="CellMarker").df()

When instantiating a Bionty object, we can choose a source or version:
public_source = bt.PublicSource.filter(
source="cellmarker", version="2.0", organism="human"
).one()
public = bt.CellMarker.public(public_source=public_source)
public
