CD34 antibody | MEC14.7
Rat anti Mouse CD34 antibody, clone MEC14.7 (MCA1825) used for the identification of CD34 expressing cells in CRC liver metastases in mouse liver by immunohistochemistry on formalin fixed paraffin embedded tissue sections following heat mediated antigen retrieval in citrate buffer.
Image caption:
Differences in blood vessel morphology between tumor periphery and center.A: Formalin fixed liver sections with CRC liver metastases were stained with antibodies to CD34 (staining of endothelial cells on immature vessels). Scale bar=200μm. Inset 1 depicts tumor vessels (arrows) in the tumor center staining strongly for the CD34 endothelial marker. Inset 2 depicts tumor vessels (arrows) in the tumor periphery staining weakly for the CD34. Inset 3 depicts host vessels (arrows) being co-opted by the tumor displaying weak or no CD34 staining. B: Quantification of CD34 positive vessels in tumor center and tumor periphery expressed as CD34 positive vessels /mm2. Black bars = tumor periphery, Grey bars = tumor center. Significantly more CD34 positive vessels are seen in the tumor center (*P<0.001). Quantification of αSMA pericyte association with tumor vessels revealed a significantly greater number in the tumor periphery compared to the tumor center (* P<0.0001, Black bars = tumor periphery, Grey bars = tumor center. Data is expressed as mean value ± SEM, with n≥5 for each group. Data was not normally distributed and non-parametric analysis was performed and statistical significance determined using Kruskal Wallis and Mann-Whitney U test.

Image caption:
Changes in endothelial cells and vessel morphology following OXi4503 treatment. Mice were treated with a single IP dose of OXi4503 (100mg/kg) at 16 days after tumor induction. Tissues were collected at one hour, 24 hours and five days after treatment. Formalin fixed liver sections were stained with anti-CD34 antibody to visualize tumor vessels. (A), Control tumor, arrow indicates a patent tumor vessel; 1hr OXi4503, arrows indicate endothelial cells rounding up and detaching from the vessel basement membrane; 1hr OXi4503, EC apoptosis, the section was doubly immunostained for CD34 and active caspase-3 (apoptosis marker), to visualise endothelial cells undergoing apoptosis (arrows); 24hrs OXi4503 center, arrow points at a totally occluded tumor vessel; 24hrs OXi4503 periphery, arrow indicates patent tumor vessel; 5 days OXi4503 , center, demonstrating regenerating tumor vessels surrounded by proliferating tumor cells; Single staining magnification scale bar=50μm, double staining magnification scale bar=25μm. (B), Enumeration of vascular endothelial cell apoptosis show significant differences between the tumor center and periphery at one and 24 hours after treatment (*P <0.001); (C), Quantification of tumor vascular changes following OXi4503 treatment. Vascular density decreased significantly in the tumor center (**P<0.0001), but not the periphery (P=0.173) at 24 hours after treatment. Tumor revascularization at day five is significantly higher compared to the untreated control both at tumor center and the periphery (*P=0.001). Results are mean values ± SEM, (n≥5). Black bars = tumor periphery, Grey bars = tumor center.

Image caption:
Differences in blood vessel density following different treatment regimens. a Formalin fixed liver sections with CRC liver metastases were stained with antibodies to CD34 (staining of endothelial cells). First column Scale bar = 200μm. Second column depicts magnified inset regions of first column images. Scale bar = 50μm. T = live tumor, NT = necrotic tumor. Second inset in the OXi4503 treatment indicates central tumor vessels recovering ahead of live tumor repopulation. Arrow in the Sunitinib treatment indicates intact central vessel surrounded with live tumor cells. Arrows in the combination treatment show liver damage. b Quantification of CD34 positive vessels. Data is expressed as mean value ± SEM, with n ≥ 5 for each group. Data was not normally distributed and non-parametric analysis was performed and statistical significance determined using Mann-Whitney U test.

Rat anti Mouse CD34 antibody, clone MEC14.7 (MCA1825) used to evaluate tumor angiogenesis in CBA mice by immunohistochemistry on formalin fixed, paraffin embedded tissue sections.
Image caption:
Effect of kinin receptor inhibition on tumor angiogenesis in CBA mice induced with CRLM. Tumor blood vessels were visualised by immunostaining for CD34 endothelial cell marker (brown staining). a,c&e magnification 5×, a,d&f (corresponding insets) magnification 20×, 0 to 100 images at 20× magnification of stained tumor from each mouse were taken in a pre-determined systematic fashion. CD34 positive blood vessels were counted using Image ProPlus 6. SSR240612 (SSR) and FR173657 (FR) treatment significantly reduced tumor angiogenesis compared to control (CTRL) shown in g. Results are presented as group mean value ±SD, (n=6) (*p < 0.001; **p <0.0001 compared to control)

| Rat anti Mouse CD34 antibody, clone MEC14.7 recognizes the murine CD34 cell surface antigen, which is expressed by endothelial cells and by haematopoietic stem cells. This antibody recognizes a neuraminidase sensitive epitope. As in the human system, CD34 antibodies in the mouse demonstrate slightly different staining patterns depending on their fine specificity. Rat anti Mouse CD34 antibody, clone MEC14.7 appears to recognize a subset of the stem cell population recognized by clone RAM34, and it is thought that this is due to differences in the epitope recognized by the two antibodies. |
