What it is
RNA-seq (gene expression)Gene activity measured by sequencing. The summary does not mention single-cell work, so this is most likely bulk: one average per sample, the usual starting point for comparing groups.

Data you can get
A processed table (series matrix) and supplementary files from NCBI; the raw sequencing reads from ENA. Which of these hold counts depends on the study, so check the file list.

Summary (written by the submitters)
Differentiated chondrocytes from populations of human bone marrow stromal cells including skeletal stem cells (hBMSCs/SSCs) and induced pluripotent stem cells (hiPSCs) have the potential to restore damaged cartilage, yet chondrocyte hypertrophy is a barrier for translational therapy. However, hBMSCs/SSCs attached to a hyaluronic acid-coated fibrin microbead scaffold (HyA-FMBs) produce cartilage that resists hypertrophy.
Read the full summary ↓
We show that HyA-FMBs initially suppress Bone Morphogenic Protein (BMP) signaling early in chondrogenic differentiation of hBMSCs/SSCs, then restore BMP signaling in a stable chondrogenic population enriched for Insulin-like Growth Factor Binding Protein 5 and Matrix Gla Protein. We subsequently developed a serumfree hiPSC differentiation strategy that inhibited, then activated BMP signaling in a purified subpopulation derived from ?chondrospheroids? that exhibited stable expression of Type II Collagen, Aggrecan (ACAN), and Lubricin (PRG4) and minimal e xpression of Type X Collagen. Overall, timed, and selective BMP signaling restrains chondrocyte hypertrophy, supporting the potential of chondrospheroid-derived cells for clinical utility in osteoarthritis.

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 GSE242524_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: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA1013808 and SRA study SRP459051. Searching any of these in the dataset finder brings you back here.
