*  Lymph node stromal cell - Wikipedia
Lymph node stromal cells are essential to the structure and function of the lymph node. There are a number of different types of lymph node stromal cells which have a number of functions including: creating a tissue scaffold within lymph nodes for the support of hematopoietic cells; the release of small molecules that are chemical messengers that facilitate interactions between hematopoietic cells; the facilitation of the migration of hematopoietic cells; the presentation of antigens to immune cells at the initiation of the adaptive immune system; and the homeostasis of lymphocyte numbers. Stromal cells originate from multipotent mesenchymal stem cells. Lymph ...
*  Lymph node biopsy - Wikipedia
Lymph node biopsy is a test in which a lymph node or a piece of a lymph node is removed for examination under a microscope (see: biopsy). The lymphatic system is made up of several lymph nodes connected by lymph vessels. The nodes produce white blood cells (lymphocytes) that fight infections. When an infection is present, the lymph nodes swell, produce more white blood cells, and attempt to trap the organisms that are causing the infection. The lymph nodes also try to trap ...

*  swollen lymph nodes and more - I cannot get a diagnosis. - Condition | Our Health
Sorry for all this serious information.Lymph nodes can become swollen because of infection, inflammatory conditions, an abscess or cancer. Infections are the most common cause of swollen lymph nodes. The location of the swollen lymph node can tell you where the infection is. An infection in the feet, legs or genital area -- it can be as simple as athlete's foot or an ingrown toenail -- may cause lymph nodes in the groin to swell. A swollen lymph node in the armpit might be from an infected cut on the arm or finger. Allergies and bug bites can also cause lymph nodes to swell.Most people connect the term ...
*  What Swollen Lymph Nodes Are Telling You | Medical Wiki - Medical Jobs, Careers And Information
If you feel that you are having some swollen lymph nodes but do not know how to have them treated or what is it about, then this article can help you run through that. These lymph nodes are often found in different areas such as the groin, your armpit, your neck (there are a couple of nodes found at the front of your neck, on both sides and at the lower back of your neck), under the chin and your jaw, behind the ears and even at the back of your head. Some of the reason why they can be swollen are infections of the ear, tonsils, and skin; inflammation due to impacted tooth, mouth sores and gingivitis, colds and flu, viral illness, sexually transmitted diseases, tuberculosis, mononucleosis and even cancer.. Some swollen lymph nodes are common that they go ...
*  swollen lymph nodes - Anxiety - Panic Disorders - HealingWell.com Forum
Hey everyone. I've been freaking out about something for a while now and it all started a year ago when I got mono. I had mono for a few months and one of the major symptoms of mine was a really bad sore throat. As time went on I began researching swollen lymph nodes (bad idea) and soon developed a fear of having lymphoma. So basically a year after mono my lymph nodes in my neck are still swollen. these lymph nodes are located underneath my jaw and are rather hard/rubbery and they don't really move very much. I felt the lymph nodes under my moms jaw and I remember feeling a pea sized movable squishy one which seemed harmless. But mine are probably around 2-3cm large. when I tilt my head and neck back, I can ...
Results-Most benign lymph nodes were slightly darker or the same in brightness compared with surrounding tissue, whereas most metastatic nodes were obviously darker. The mean area ratio of benign lymph nodes ± SD (1.05 ± 0.15) was statistically lower than the mean area ratio of metastatic lymph nodes (1.39 ± 0.20; P , 0.001). The area ration cutoff level for metastatic lymph nodes was estimated to be 1.16. With the use of a receiver operating characteristic curve with this cutoff value, the area ratio predicted malignancy with sensitivity of 91.1%, specificity of 83.3%, and an area under the curve of 0.925. ...

*  Pretreatment Lymph Node Dissection May Improve Survival in Advanced Cervical Cancer, But for Too Few? - The ASCO Post
Women with cervical cancer metastasized to para-aortic lymph nodes have historically had a poor prognosis, with 3-year overall survival rates of 25% to 40%.1-3 This has been attributed to the presence of occult systemic disease at the time of presentation and a high rate of distant recurrences following therapy.. The practice of pretreatment para-aortic lymph node dissection among patients with locally advanced cervical cancer, as in the study reported by Gouy et al, remains a controversial practice. The potential benefit is supportable by three assumptions: (1) that pretreatment imaging assessment of lymph node involvement is limited, (2) that treatment will be modified based on the findings of the lymph node dissection, and (3) that these ...
*  PLOS ONE: The Prognostic Value of Harvested Lymph Nodes and the Metastatic Lymph Node Ratio for Gastric Cancer ...
Aim To investigate whether the recommendation to remove 15 lymph nodes that is used in the staging system is necessary to assess gastric cancer progression and to evaluate whether our metastatic lymph node ratio dividing method, adapted from the AJCC's (American Joint Committee on Cancer) 7th TNM staging system, is helpful for the patients with fewer than 15 harvested lymph nodes. Methods We performed a retrospective study of 1101 patients with histologically diagnosed gastric cancer who underwent a D2 gastrectomy at the Sun Yat-sen University Cancer Center between January 2001 and December 2010. The Kappa and Chi-squared tests were employed to compare the clinicopathological variables. The Kaplan-Meier method and Cox regression were employed for the univariate and multivariate survival analyses. Results ...

*  Popliteal lymph nodes - Wikipedia
The popliteal lymph nodes, small in size and some six or seven in number, are embedded in the fat contained in the popliteal fossa, sometimes referred to as the 'knee pit'. One lies immediately beneath the popliteal fascia, near the terminal part of the small saphenous vein, and drains the region from which this vein derives its tributaries, such as superficial regions of the posterolateral aspect of the leg and the plantar aspect of the foot. Another is between the popliteal artery and the posterior surface of the knee-joint. It receives afferents from the knee-joint, together with those that accompany the genicular arteries. The others lie at the sides of the popliteal vessels, and receive, as efferents, the trunks that accompany the anterior and posterior tibial vessels. The efferents of the popliteal lymph nodes pass almost entirely alongside the femoral vessels to the ...

Background Lymph node metastasis is a key event in the progression of breast cancer. Therefore it is important to understand the underlying mechanisms which facilitate regional lymph node metastatic progression. Methodology/Principal Findings We performed gene expression profiling of purified tumor cells from human breast tumor and lymph node metastasis. By microarray network analysis, we found an increased expression of polycomb repression complex 2 (PRC2) core subunits EED and EZH2 in lymph node metastatic tumor cells over primary tumor cells which were validated through real-time PCR. Additionally, immunohistochemical (IHC) staining and quantitative image analysis of whole tissue sections showed a significant increase of EZH2 expressing ...
*  Cd11c+B220+Gr-1+ Cells in Mouse Lymph Nodes and Spleen Display Characteristics of Plasmacytoid Dendritic Cells | JEM
By examining cell populations that are reduced in the LN of L-selectin-deficient mice, we identified a novel murine cell type, CD11c+CD11b−B220+Gr-1+ DCs, that displays several characteristics of human pDCs. Similarities between CD11c+Gr-1+ cells and human pDCs include their apparent L-selectin-dependent migration across HEVs (14), their plasmacytoid morphology (11), their immature phenotype when freshly isolated from lymphoid organs (11), their localization within T cell zones (10), their activation by CpG (13), and their production of IFNα after viral stimulation (12). Taken together, these similarities strongly suggest that the CD11c+Gr-1+ cells we describe are the murine counterpart of human pDCs.. Several differences between the cells we describe and human pDCs should be noted. First, the cells we describe are CD11c+, while human pDCs in blood and tissues lack CD11c expression. The role played by CD11c on DCs is not known, so the functional significance of this ...

Replied on 04/19/2011 Lumps can be secondary to inflammation, infection, tumors (both malignant which are aggressive and invasive or benign which are not aggressive or invasive) as well as a normal part of anatomy. If the bumps are right below both of her eyes they may be normal lymph nodes or lymph nodes which have enlarged secondary to infection, inflammation or a cancer called lymphosarcoma. If those are the only lymph nodes that are enlarged then it may be due to a localized inflammation or infection, cancer would be unlikely.
