Gene expression (Cd146, Col1a1, Mkx, Scx, and Tnmd) of CD146+ MACS-sorted pericytes isolated from tail tendons of Scx+ and ScxΔ mice cultured on type I collagen gels for 1D, 3D, or 5D. Values are mean ± CV. Differences between groups were tested using 2-way ANOVA; a, significantly different (P < 0.05) from 1D Scx+; b, significantly different (P < 0.05) from 1D ScxΔ; c, significantly different (P < 0.05) from 3D Scx+; d, significantly different (P < 0.05) from 3D ScxΔ; e, significantly different (P < 0.05) from 5D Scx+. Values are mean ± CV. N = 6 replicates per group.
