Mouse Gastrulation scRNA-seq data

Across the animal kingdom, gastrulation represents a key developmental event during which embryonic pluripotent cells diversify into lineage-specific precursors that will generate the adult organism.

Project information

  • Source: scRNA-seq whole mouse embryos during gastrulation and organoienesis, spanning days 6.5 to 8.5 of development, including embryonic and extraembryonic tissues.

  • Raw file:

  • Species

    • Mus musculus (Mouse)

Assay details

  • Assay: 10X Genomics Chromium system (version 1 chemistry)
  • Number of Cells: 139,331
  • Number of Genes: 29,452

Load the data

Load the dataset using Huggingface's optimized library and create the AnnData object:

from datasets import load_dataset
from scipy.sparse import lil_matrix
ds = load_dataset("helical-ai/gastrulation_mmusculus",trust_remote_code=True, split="train[:65%]",download_mode="reuse_cache_if_exists")

observation_columns = [obs for obs in list(ds.features.keys()) if not obs == 'raw_counts']
obs_data = pd.DataFrame(ds.select_columns(observation_columns).data.to_pandas(),columns=observation_columns)
lil = lil_matrix((len(ds),ds[0]['size']))
lil.data = np.array(ds['raw_counts'],dtype="object")
lil.rows = np.array(ds['rows'],dtype="object")
ann_data = ad.AnnData(lil.tocsr(),obs=obs_data)
ann_data.var_names = ds.features['raw_counts'].id.split(",")
