Summary (written by the submitters)
Robust and reliable and in vitro models are essential in the discovery of new treatment options for high-grade glioma (HGG), however, establishing successful patient-derived cell cultures has posed significant challenges. We established glioma stem-like cell (GSC) cultures from 114 consecutive HGG specimens, obtained via traditional surgical resection and/or ultrasonic aspiration, using fully-dissociated single cells (single cell-derived, SCD) and partially dissociated tissue fragments (3D-derived, 3DD).

Copy number profiling assessed genetic similarities, while single-cell RNA sequencing evaluated transcriptomic heterogeneity. Proof-of-concept personalized drug screening was performed using a panel of approved anti-cancer agents. Higher success rates in establishing GSC cultures were obtained from ultrasonic aspirates (SCD and 3DD) and 3DD surgical samples compared to SCD cultures from surgical samples. Combining these approaches in parallel yielded a 96% success rate. In rare cases, copy number variations in original tumor tissue were lost in culture, leading to discernible changes in cell morphology. Single-cell sequencing revealed greater heterogeneity of transcriptomic clusters in ultrasonic aspiration-derived cultures compared to resection-derived cultures. Our study's protocol supported the screening of 20 anti-cancer agents within a clinically-relevant timeframe in 16 of 18 consecutive HGG samples. Our optimized protocol therefore provides a reliable tool for generating HGG cell cultures which capture the tumors’ molecular characteristics and supports precision medicine applications.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE248543_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: Single-cell studies usually ship their counts as 10x files (matrix.mtx, barcodes.tsv, features.tsv), an .h5 file, or an .rds / .h5ad object that Seurat or Scanpy can open. Look for those among the supplementary files.

Also filed as BioProject PRJNA1044752 and SRA study SRP473986. Searching any of these in the dataset finder brings you back here.
