Expression of Jagged2 in endothelial cells but not in fibroblasts.
Total cell lysates were resolved by SDS-PAGE, blotted onto membranes, and probed with anti-ICD antibodies and horseradish peroxidase-conjugated second antibodies. (A) Expression of Jagged2 protein in HUVEC. Lane 1, Rab-9/LXSN (negative control; see below); lane 2, Rab-9/LMJSN (positive control; see below); lane 3, HUVEC; lane 4, S17. The position of the approximately 150-kd Jagged2 protein is indicated. (B) Lack of Jagged2 protein expression in marrow stromal fibroblast cell lines. Lane 1, Rab-9/LXSN (negative control; see below); lane 2, Rab-9/LMJSN (positive control; see below); lane 3, stromal cell line STS; lane 4, stromal cell line STD; lane 5, stromal cell line STW; lane 6, stromal cell line STV; lane 7, stromal cell line S17. The position of the approximately 150-kd Jagged2 protein is shown. (C) Northern blot analysis of Jagged2 expression in endothelial cells and stromal fibroblasts. Each lane contained 5 μg total RNA. The blot was hybridized to a 1:1 mixture of full-length h-Jagged2 and mJagged2 probes. Lane 1, EML C1 (positive control); lane 2, HUVEC; lane 3, HUVEC treated with apolipoprotein-a [apo(a)] for 12 hours; lane 4, STS; lane 5, STD; lane 6, STW; lane 7, STV. The position of 28S rRNA is marked.
