Co-expression network analysis of lncRNAs A Hierarchical clustering tree of all samples. B The determination of soft thresholding power (β = 7) by scale free topology model fit (left) and mean connectivity (right). C The clustering dendrogram demonstrates lncRNAs were separated into various modules based on the dynamic hybrid-cutting method. D The eigengene adjacency heatmap with the module clustering tree (above) and the corresponding module clustering heatmap (below). E Topological overlap matrix for all lncRNAs in each module. F Module-trait relationship heatmap exhibiting the correlation coefficient between each module and the four adipogenesis stages. G The Gene Module Membership and the gene Trait Cor scattering distribution of turquoise vs. 3 d (left), yellow vs. 3 d (middle), and red vs. 3 d (right)
