mRNA expression of IL-11, leukaemia inhibitory factor (LIF), oncostatin M (OSM) and IL-6 in unstimulated bone marrow stromal cells (BMSC) and osteoblasts (OB) isolated from one OA, one RA and one post-traumatic (PT) patient, as described in Patients and Methods. Lanes 1, 4, BMSC and OB from an OA patient; lanes 2, 5, BMSC and OB from an RA patient; lanes 3, 6, BMSC and OB from a PT patient; N, negative control (FRTL5 cell line); M, molecular weight marker (123-bp ladder). GAPDH was used as a quality control.
