Western blot shows lysates of human kidney (cortex) tissue. PVDF Membrane was probed with 1 µg/mL of Sheep Anti-Human CD157 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4736) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for CD157 at approximately 45 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Background

CD157, also known as bone marrow stromal cell antigen 1 (BST-1), is a glycosyl phosphatidylinositol anchored membrane protein that belongs to the CD38 family (1). CD157 was discovered in a bone marrow stromal cell line where it facilitates pre-B-cell growth (2, 3). Along with CD38, CD157 is a bifunctional ectoenzyme that exhibits both ADP-ribosyl cyclase and cyclic ADP ribose hydrolase activities (2). It may play a role in rheumatoid arthritis (RA) due to its enhanced expression in RA‑derived bone marrow stromal cell lines (3). CD157 has been predicted to function as a cell surface receptor and an immunoregulatory molecule (4).

Effects of SDF-1-CXCR4/CXCR7 pathway on MSC chemotaxis in vitro.(A) The chemotaxis in response to SDF-1 alpha (10 ng/ml for 12 h) was performed in the NP-MSCs and HP-MSCs treated with a neutralizing anti-CXCR4 antibody, an anti-CXCR7 antibody, and the respective isotype-matched control antibodies. *P<0.05, vs NP-MSCs; †P<0.05, vs the respective isotype-matched control antibodies. (B) NP-MSCs were transiently overexpressed with CXCR4 using pORF9-mCXCR4 vector or with CXCR7 using pORF9-mCXCR7 vector (n = 6). A negative control empty (pORF9-MCS) vector was used. (C) The transfected cells were subjected to chemotaxis in response to the indicated concentrations of SDF-1 alpha for 12 h. *P<0.05, vs the empty vector. (D and E) Western blot analysis (D) and FCM (E) were performed to determine the intracellular and extracellular expression of both CXCR4 and CXCR7 in the cells treated with or without SDF-1 alpha (50 ng/ml for 60 min). (F) The chemotaxis in response to SDF-1 alpha was performed in the cells treated with or without SDF-1 alpha .
