      <STUDY_ABSTRACT>Single cell RNA sequencing data was collected from 150 day old human cortical organoid slice cultures grown at the air-liquid interface (ALI-COs) from control and ALS/FTD patient-specific induced pluripotent stem cell (iPSC) lines harbouring the C9ORF72 hexanucleotide repeat expansion mutation. Data collection included ALI-COs derived from the following iPSC lines: WTSli042-B (WTS42b) and A18945 (EpiC) for healthy controls, CS30iALS-C9nxx (CS30) and CS29iALS-C9nxx (CS29) for ALS/FTD, and CS29iALS-C9n1.ISOxx (ISO29), a mutation-corrected isogenic line. A total of 148,223 cells were processed over two batches. Overall design: Single cell RNA-sequencing data was generated using the 10X Genomics Chromium Single Cell 3' Chip and workflow.</STUDY_ABSTRACT>
