N-Acetyl-L-cysteine facilitates tendon repair and promotes the tenogenic differentiation of tendon stem/progenitor cells by enhancing the integrin α5/β1/PI3K/AKT signaling

N-acetyl-L-cysteine (NAC) is a potent antioxidant. However, how NAC affects the biological functions of tendon stem/progenitor cells (TSPCs) and tendon repair has not been clarified.The effect of NAC on gene transcription in TSPCs was analyzed by transcriptomes and bioinformatics. We then performed gene expression bioinformatics analysis using data obtained from RNA-seq of 2 group different cells after 7 days culturing.
