Semaphorin 3C in MCF‑7 Human Cell Line. Semaphorin 3C was detected in immersion fixed MCF‑7 human breast cancer cell line using Sheep Anti-Mouse Semaphorin 3C Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1728) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red; Catalog # NL010) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Semaphorin 3C in Mouse Embryo. Semaphorin 3C was detected in immersion fixed frozen sections of mouse embryo (15 d.p.c.) using Sheep Anti-Mouse Semaphorin 3C Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1728) at 1.7 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific labeling was localized to the plasma membrane of mesenchymal cells. View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections.

Background: Semaphorin 3C
Semaphorin 3C (Sema 3C; previously semaE) is one of six Class 3 secreted semaphorins which share 40-50% amino acid (aa) identity. Class 3 semaphorins are potent chemorepellents that function in axon and/or vascular guidance during development, and may be upregulated in tumor progression (1, 2). The 751 amino acid (aa) mouse Sema3C is highly modular. It contains a 20 aa signal sequence, an ~500 aa N-terminal Sema domain that forms a beta -propeller structure similar to that found in integrin molecules, a cysteine knot, a furin-type cleavage site, an Ig-like domain, and a C-terminal basic domain (1-3). Covalent dimerization plus cleavage at the C-terminus are required for activity of class 3 semaphorins (4). Mouse Sema 3C shares at least 95% aa identity with human, rat, cow and dog Sema 3C, and 89% and 75% aa sequence identity with chick and zebrafish Sema 3C, respectively. Type 3 semaphorins transduce signals through transmembrane plexins, either directly or by binding associated neuropilin receptors (1, 2). Sema 3C signaling is transduced by Plexin-D1 indirectly via neuropilin-1 or neuropilin-2 receptors (5). Sema 3C is expressed in all somitic motor neurons, in lung buds and in cardiac neural crest cells during development (1, 5-8). Sema 3C activates integrins in certain cells so, in addition to its repulsive activities, it sometimes acts as a chemoattractant (6, 9). In the developing nervous system, this chemoattraction appears to complement Sema 3A repulsion in adjacent cell layers (1, 6, 7). Sema 3C also provides an attractive force opposing Sema 6A and Sema 6B to guide migration of neural crest endothelial cells to the cardiac outflow tract (10). Consequently, defects in aortic arch formation occur when Sema 3C or Plexin-D1 genes or Sema 3C-neuropilin interactions are disrupted (5, 11, 12).
