Abstract: Angiogenesis involves a complex set of cell–cell and cell–extracellular matrix (ECM) interactions that coordinately promote and inhibit blood vessel growth and sprouting. Although many factors that promote angiogenesis have been characterized, the identities and mechanisms of action of endogenous inhibitors of angiogenesis remain unclear. Furthermore, little is known about how cancer cells selectively circumvent the actions of these inhibitors to promote pathological angiogenesis, a requisite event for tumor progression. Using mosaic mouse models of the malignant brain cancer, astrocytoma, we report that tumor cells induce pathological angiogenesis by suppressing expression of the ECM protein receptor αvβ8 integrin. Diminished integrin expression in astrocytoma cells leads to reduced activation of latent TGFβs, resulting in impaired TGFβ receptor signaling in tumor-associated endothelial cells. These data reveal that astrocytoma cells manipulate their angiogenic balance by selectively suppressing αvβ8 integrin expression and function. Finally, these results show that an adhesion and signaling axis normally involved in developmental brain angiogenesis is pathologically exploited in adult brain tumors.

Spirulina Promotes Stem Cell Genesis and Protects against LPS Induced Declines in Neural Stem Cell Proliferation. PLoS ONE 5(5): e10496. doi:10.1371/journal.pone.0010496.
Abstract:Adult stem cells are present in many tissues including, skin, muscle, adipose, bone marrow, and in the brain. Neuroinflammation has been shown to be a potent negative regulator of stem cell and progenitor cell proliferation in the neurogenic regions of the brain. Recently we demonstrated that decreasing a key neuroinflammatory cytokine IL-1β in the hippocampus of aged rats reversed the age-related cognitive decline and increased neurogenesis in the age rats. We also have found that nutraceuticals have the potential to reduce neuroinflammation, and decrease oxidative stress. The objectives of this study were to determine if spirulina could protect the proliferative potential of hippocampal neural progenitor cells from an acute systemic inflammatory insult of lipopolysaccharide (LPS). To this end, young rats were fed for 30 days a control diet or a diet supplemented with 0.1% spirulina. On day 28 the rats were given a single i.p. injection of LPS (1 mg/kg). The following day the rats were injected with BrdU (50 mg/kg b.i.d. i.p.) and were sacrificed 24 hours after the first injection of BrdU. Quantification of the BrdU positive cells in the subgranular zone of the dentate gyrus demonstrated a decrease in proliferation of the stem/progenitor cells in the hippocampus as a result of the LPS insult. Furthermore, the diet supplemented with spirulina was able to negate the LPS induced decrease in stem/progenitor cell proliferation. In a second set of studies we examined the effects of spirulina either alone or in combination with a proprietary formulation (NT-020) of blueberry, green tea, vitamin D3 and carnosine on the function of bone marrow and CD34+ cells in vitro. Spirulina had small effects on its own and more than additive effects in combination with NT-020 to promote mitochondrial respiration and/or proliferation of these cells in culture. When examined on neural stem cells in culture spirulina increased proliferation at baseline and protected against the negative influence of TNFα to reduce neural stem cell proliferation. These results support the hypothesis that a diet enriched with spirulina and other nutraceuticals may help protect the stem/progenitor cells from insults. Figure 7. Spirulina increases proliferation of human neural stem cells in vitro and protects against a TNFα insult.

STEMEZ(TM) hNP1 Human Neural Progenitors and hN2 Primary Neurons Differentiation and Expression

INTRODUCTION
Human embryonic stem cells and their progeny can provide a novel Distribution of detectable transcripts for three cell populations tissue source for understanding developmental pathways, pharmaceutical screening and tissue replacement therapies. G-protein coupled receptors(GPCRs) comprise the largest cell-surface receptor superfamily and are the largest class of drug targets. The study of GPCR signaling in hES cells allows signaling mechanisms to be studied in endogenously expressed receptors in non-transformed cells. We characterized GPCR transcript expression in three cellular populations at different developmental stages: WAO9 human embryonic stem cells, Wa09 derived STEMEZ hNP1 and differentiated hN2 cells maintained 1 week in culture.
Goal: To characterize GPCR transcript expression in human hES cell derived neural tissue
CONCLUSIONS
• hES cells displayed the widest array of GPCR transcripts, while neural progenitors displayed the most restricted population.
• The Frizzled (FZD) family of receptors were among the most abundantly expressed transcripts across all populations.
• Neural progentitors up-regulated GPCR transcripts important to brain angiogenesis, cell proliferation, neurogenesis and cell adhesion.
• Further differentiated hN2 cells displayed up-regulation of a wider population of transcripts including GPCRs involved with neurotransmission.
• Functional assays demonstrated responses to sphingosine-1-phosphate in both hNP1 and hN2 populations of cells.
• hES cells and their derived tissue provide a unique model to study endogenous GPCR signaling in non-transformed cells for drug screening applications and to further our understanding of GPCRs role in developmental pathways.

Posted using ShareThis
I have profiled Steve Stice's research here. The focus has been the excellent research results he and his team at ArunA Biomedical have generated with STEMEZ(TM) hN2 Human Neurons and hNP1 Human Neural Progenitors.
The story continues. He will be presenting the latest at the 9th Annual World Pharmaceutical Congress in Philadelphia, June 14. Topics include: using these neural cell lines to study neurotoxicity in cell-based assays and disease modeling. Recent work conducted in outside laboratories demonstrates that these lines are more sensitive to environmental toxicants than traditional cellular models.
Sample high throughput assay applications:
- Cell morphology and neurite outgrowth
- Cell signaling and transcription factor expression
- Receptor and ion channel function
- Cytotoxicity
- Apoptosis, genotoxicity and DNA damage
These capabilities has been confirmed by our customers. I look for the use of the STEMEZ cell lines to continue to grow as researchers discover their value in Drug Discovery and Basic Neuroscience capabilities.

Blood, May 2010; 115: 3843 - 3851
Anti-rat antibodies used in this study are: anti-CD117 (Neuromics) and anti-CD146
Abstract: CD146, an endothelial molecule involved in permeability and monocyte transmigration, has recently been reported to promote vessel growth. As CD146 is also detectable as a soluble form (sCD146), we hypothesized that sCD146 could stimulate angiogenesis. Experiments of Matrigel plugs in vivo showed that sCD146 displayed chemotactic activity on endogenous endothelial cells, and exogenously injected late endothelial progenitor cells (EPCs). Recruited endothelial cells participated in formation of vascular-like structures. In vitro, sCD146 enhanced angiogenic properties of EPCs, with an increased cell migration, proliferation, and capacity to establish capillary-like structures. Effects were additive with those of vascular endothelial growth factor (VEGF), and sCD146 enhanced VEGFR2 expression and VEGF secretion. Consistent with a proangiogenic role, gene expression profiling of sCD146-stimulated EPCs revealed an up-regulation of endothelial nitric oxide synthase, urokinase plasminogen activator, matrix metalloproteinase 2, and VEGFR2. Silencing membrane-bound CD146 inhibited responses. The potential therapeutic interest of sCD146 was tested in a model of hind limb ischemia. Local injections of sCD146 significantly reduced auto-amputation, tissue necrosis, fibrosis, inflammation, and increased blood flow. Together, these findings establish that sCD146 displays chemotactic and angiogenic properties and promotes efficient neovascularization in vivo. Recombinant human sCD146 might thus support novel strategies for therapeutic angiogenesis in ischemic diseases

TRPV1 Expression and Temporal Lobe Epilepsy
In this excellent study they showed an increase in expression in TLE mice vs controls.
Muthu D. Bhaskaran and Bret N. Smith. Effects of TRPV1 activation on synaptic excitation in the dentate gyrus of a mouse model of temporal lobe epilepsy. doi:10.1016/j.expneurol.2010.01.021
...with polyclonal VR1 N-terminus (1:2500) (Neuromics, Edina)..
Abstract: Temporal lobe epilepsy (TLE) is a condition characterized by an imbalance between excitation and inhibition in the temporal lobe. Hallmarks of this change are axon sprouting and accompanying synaptic reorganization in the temporal lobe. Synthetic and endogenous cannabinoids have variable therapeutic potential in treating intractable temporal lobe epilepsy, in part because cannabinoid ligands can bind multiple receptor types. This study utilized in vitro electrophysiological methods to examine the effect of transient receptor potential vanilloid type 1 (TRPV1) activation in dentate gyrus granule cells in a murine model of TLE. Capsaicin, a selective TRPV1 agonist had no measurable effect on overall synaptic input to granule cells in control animals, but significantly enhanced spontaneous and miniature EPSC frequency in mice with TLE. Exogenous application of anandamide, an endogenous cannabinoid that acts at both TRPV1 and cannabinoid type 1 receptors (CB1R), also enhanced glutamate release in the presence of a CB1R antagonist. Anandamide reduced the EPSC frequency when TRPV1 were blocked with capsazepine. Western blot analysis of TRPV1 receptor indicated protein expression was significantly greater in the dentate gyrus of mice with TLE compared with control mice. This study indicates that a prominent cannabinoid agonist can increase excitatory circuit activity in the synaptically reorganized dentate gyrus of mice with TLE by activating TRPV1 receptors, and suggests

CFR1, 5-HT2AR and Anxiety Behavior
We are pleased to present a new publication referencing use of our 5HT (Serotonin) 2A Receptor Antibody. Dr. Stephen S G Ferguson and team have discovered a link between CFR1 and 5-HT2A Receptor expression:
Ana C Magalhaes,Kevin D Holmes,Lianne B Dale,Laetitia Comps-Agrar,Dennis Lee,Prem N Yadav, Linsay Drysdale, Michael O Poulter, Bryan L Roth, Jean-Philippe Pin, Hymie Anisman& Stephen S G Ferguson. CRF receptor 1 regulates anxiety behavior via sensitization of 5-HT2 receptor signaling. Nature Neuroscience. doi:10.1038/nn.2529. Published online11 April 2010.
Abstract: Stress and anxiety disorders are risk factors for depression and these behaviors are modulated by corticotrophin-releasing factor receptor 1 (CRFR1) and serotonin receptor (5-HT2R). However, the potential behavioral and cellular interaction between these two receptors is unclear. We found that pre-administration of corticotrophin-releasing factor (CRF) into the prefrontal cortex of mice enhanced 5-HT2R–mediated anxiety behaviors in response to 2,5-dimethoxy-4-iodoamphetamine. In both heterologous cell cultures and mouse cortical neurons, activation of CRFR1 also enhanced 5-HT2 receptor–mediated inositol phosphate formation. CRFR1-mediated increases in 5-HT2R signaling were dependent on receptor internalization and receptor recycling via rapid recycling endosomes, resulting in increased expression of 5-HT2R on the cell surface. Sensitization of 5-HT2R signaling by CRFR1 required intact PDZ domain–binding motifs at the end of the C-terminal tails of both receptor types. These data suggest a mechanism by which CRF, a peptide known to be released by stress, enhances anxiety-related behavior via sensitization of 5-HT2R signaling.

Neuropeptides and Large Dense Core Vesicles
We wanted to feature an new article referencing use of our Guinea Pig Substance Antibody. Dr. Richard Mains and his team shed light on the function and behavior of large dense core
vesicles (LDCVs) concluding that under basal conditions, LDCVs move faster away from the soma than toward the soma, but fewer LDCVs travel anterograde than retrograde. Stimulation decreased average anterograde velocity and increases granule pausing. Data from antibody uptake, quantification of enzyme secretion and appearance of pHluorin fluorescence demonstrate distributed release of peptides all along the axon, not just at terminals.

The researchers successfully induced neural stem (NSC) and progenitor cells (NPC) from human placental tissues.
Here are the highlights:
Study Design
Placental stem cells from first-trimester placental chorionic villi and term chorion were isolated. Neural differentiation was initiated with plating on collagen, retinoic acid, and/or human brain-derived neurotrophic factor and epidermal and fibroblast growth factor. Differentiation into neurons, oligodendrocytes, and astrocytes was monitored by immunohistochemistry. Two-dimensional polyacrylamide gel electrophoresis, high-performance liquid chromatography, and tandem mass spectrometry were used to identify proteins involved in the differentiation.
Results
Differentiated cells were mostly immediately postmitotic with some more but not fully mature postmitotic neurons. Neurons had dopaminergic or serotonergic character. Some cells differentiated into predominantly immature oligodendrocytes. Upon differentiation, neuron-specific proteins were up-regulated, whereas placental proteins were reduced.
Conclusion
Stem cells derived from human placenta can be differentiated into neural progenitors.

i-Brite Plus!
i-BRITE Plus is a glycerol based liquid. It can be used to stain cells and can be easily added to wells. It also will not shrink tissue. In addition standard to IHC/IF applications, it can be used to visualize GFP transfections and more.
Here's a publication referencing it: Ajay S. Yekkirala, Alexander E. Kalyuzhny and Philip S. Portoghese. Standard Opioid Agonists Activate Heteromeric Opioid Receptors: Evidence for Morphine and [d-Ala2-MePhe4-Glyol5]Enkephalin as Selective μ−δ Agonists. ACS Chem. Neurosci., Article ASAP DOI: 10.1021/cn9000236. Publication Date (Web): November 25, 2009. Copyright © 2009 American Chemical Society.

Images: High-magnification confocal images of double-labeling immunofluorescence for HA-δ and FLAG-μ opioid receptors. HEK-293 cells stably expressing both HA-δ and FLAG-μ opioid receptors are shown labeled for μ (A, green fluorescence) and for δ (B, red fluorescence). DAPI (blue fluorescence) has been used to stain the nuclei.

Opioid Receptors and Depression
We would like to share a recent publications that sheds more light on the mystery. Our purified rabbit ployclonal phosphoERK1/2 Antibody is also referenced.
Pierluigi Onali, Simona Dedoni and Maria C. Olianas. Direct Agonist Activity of Tricyclic Antidepressants at Distinct Opioid Receptor Subtypes. JPET January 2010 vol. 332 no. 1 255-265 .
At the cloned μ-opioid receptor, TCAs showed low affinity and no significant agonist activity. These results show that TCAs differentially regulate opioid receptors with a preferential agonist activity on either δ or κ subtypes and suggest that this property may contribute to their therapeutic and/or side effects.
