Expression level of <i>HOX</i> genes in human bone marrow-derived multipotent stromal cells (BM-MSCs).

<p>The expression level of seven medium-, and low copy <i>HOX</i> transcripts is documented for biological and technical replicates of BM-MSC lines (n = 3) by 2^-ΔCT value related to <i>GAPDH</i>. (A) <i>HOX</i> genes are weakly expressed in human BM-MSCs compared to high-copy transcripts like <i>RPL13A</i> showing an expression level of about 10⁻¹ related to <i>GAPDH</i>. (B) The medium-copy <i>HOX</i> transcripts present an expression level of about 10⁻³ related to <i>GAPDH</i>. (C) The expression level of low-copy <i>HOX</i> transcripts decreases to 10⁻⁴ related to <i>GAPDH</i>.
