Expression of marker genes within Wnt/Ca2+ Signaling Pathway. (A) Violin plot showing scaled expression of differentially expressed genes defining the five chondrocyte clusters. (B) Differential expression analysis was performed comparing marker genes within Wnt/Ca2+ Signaling Pathway from NP-degenerative and NP-normal. Stars indicate significance level of gene expression difference between two samples by Wilcox test. ns, not significant; *, p value < 0.05; **, p value < 0.01; ***, p value < 0.001
