Abstract (original English)

This study employs single-cell RNA sequencing (scRNA-seq) and assay for transposase-accessible chromatin with high-throughput sequencing technologies (scATAC-seq) to perform joint sequencing on cells at various time points during the induction of adipose-derived stem cells (ADSCs) into astrocytes. We applied bioinformatics approaches to investigate the differentiation trajectories of ADSCs during their induced differentiation into astrocytes. Pseudotemporal analysis was used to infer differentiation trajectories. Additionally, we assessed chromatin accessibility patterns during the differentiation process. Key transcription factors driving the differentiation of ADSCs into astrocytes were identified using motif and footprint methods. Our analysis revealed significant shifts in gene expression during the induction process, with astrocyte-related genes upregulated and stem cell-related genes downregulated. ADSCs first differentiated into neural stem cell-like cells with high plasticity, which further matured into astrocytes via two distinct pathways. Marked changes in chromatin accessibility were observed during ADSC-induced differentiation, affecting transcription regulation and cell function. Transcription factors analysis identified NFIA/B/C/X and CEBPA/B/D as key regulators in ADSCs differentiation into astrocytes. We observed a correlation between chromatin accessibility and
