The effect of chelating agents on iron mobilization in Chang cell cultures. (1/155046)

The investigation of chelating agents with potential therapeutic value in patients with transfusional iron overload has been facilitated by the use of Chang cell cultures. These cells have been incubated with [59Fe]transferrin for 22 hr, following which most of the intracellular radioiron is found in the cytosol, distributed between a ferritin and a nonferritin form. Iron release from the cells depends on transferrin saturation in the medium, but when transferrin is 100% saturated, which normally does not allow iron release, desferrioxamine, 2,3-dihydroxybenzoic acid, rhodotorulic acid, cholythydroxamic acid, and tropolone all promote the mobilization of ferritin iron and its release from cells. They are effective to an approximately equal degree. The incubation of [59Fe]transferrin with tropolone in vitro at a molar ratio of 1:500 results in the transfer of most of the labeled iron to the chelator, reflecting the exceptionally high binding constant of this compound. How far these phenomena relate to therapeutic potentially remains to be seen.  (+info)

In vitro effects of 2,4-dichlorophenoxy acetic acid (2,4-D) on bovine cells. (2/155046)

Bovine fetal muscle cells were exposed to culture media containing 2 mg and 20 mg per liter of 2,4-dichlorophenoxy acetic acid (2,4-D) for varying intervals to determine the in vitro response of mammalian cells to this compound. The concentrations of 2,4-D used were comparable to those used in spray programmes although the residues normally found in pasture are much lower since 2,4-D is rapidly degraded under field conditions. Untreated and treated cultures were analyzed for total cell count, mitotic index and the percentages of differentiating and degenerating cells. The response of cultures to treatment was similar irrespective of the concentrations of 2,4-D used although in higher concentrations there was an initial drop in mitotic index. Other changes noted in treated cultures included an increase in differentiating and degenerating cells compared to those in control. The mitotic cells in treated cultures exhibited unipolar and tripolar spindles and a variety of other abnormalities including malorientation of the mitotic apparatus in relation to the axis of the cell. Myoblasts in initial stages of myogenesis were noted to be in mitosis in treated cultures suggesting that 2,4-D may have a stimulatory effect on myoblasts which in normal myogenesis are in post mitotic stage.  (+info)

Differences in benzo(a)pyrene metabolism between rodent liver microsomes and embryonic cells. (3/155046)

Differences in benzo(a)pyrene metabolite pattern have been shown by rodent liver microsomes (Sprague-Dawley) and rodent embryo cells from Syrian hamsters and NIH Swiss mice. Rodent liver induced by methylcholanthrene shows marked quantitative variation between species. Additional pattern changes were found in mouse and hamster embryo secondary cultures with a reduction of the K-region metabolites and a marked increase in 9-hydroxybenzo(a)-pyrene. These results are indicative of a region-specific attack on the carcinogen by the cell monooxygenases which is distinct from the liver attack of microsomal enzymes on benzo(a)pyrene. These results suggest that activation and detoxification of benzo(a)pyrene may be species and tissue variable, and susceptibility and resistence to malignant transformation may be predicted on induction of a fortuitous combination of intermediate metabolic steps.  (+info)

Glycopeptides from the surgace of human neuroblastoma cells. (4/155046)

Glycopeptides suggesting a complex oligosaccharide composition are present on the surface of cells from human neuroblastoma tumors and several cell lines derived from the tumors. The glycopeptides, labeled with radioactive L-fucose, were removed from the cell surface with trypsin, digested with Pronase, and examined by chromatography on Sephadex G-50. Human skin fibroblasts, brain cells, and a fibroblast line derived from neuroblastoma tumor tissue show less complex glycopeptides. Although some differences exist between the cell lines and the primary tumor cells, the similarities between these human tumors and animal tumors examined previously are striking.  (+info)

Stimulation of thymidine uptake and cell proliferation in mouse embryo fibroblasts by conditioned medium from mammary cells in culture. (5/155046)

Undialyzed conditioned medium from several cell culture sources did not stimulate thymidine incorporation or cell overgrowth in quiescent, density-inhibited mouse embryo fibroblast cells. However, dialyzed conditioned medium (DCM) from clonal mouse mammary cell lines MCG-V14, MCG-T14, MCG-T10; HeLa cells; primary mouse adenocarcinoma cells; and BALB/c normal mouse mammary epithelial cells promoted growth in quiescent fibroblasts. The amount of growth-promoting activity produced per cell varied from 24% (HeLa) to 213% (MCG-V14) of the activity produced by primary tumor cells. The production of growth-promoting activity was not unique to tumor-derived cells or cells of high tumorigenicity. The amount of growth-promoting activity produced per cell in the active cultures was not correlated with any of the following: tumorigenicity, growth rat, cell density achieved at saturation, cell type, or species of cell origin. It is concluded that transformed and non-transformed cells of diverse origin, cell type, and tumorigenicity can produce growth factors in culture. The growth-promoting potential of the active media from primary tumor cultures accumulated with time of contact with cells and was too great to be accounted for entirely by the removal of low-molecular-weight inhibitors by dialysis. The results are consistent with the hypothesis that conditioned medium from the active cultures contained a dialyzable, growth-promoting activity. Different cell lines exhibited differential sensitivity to tumor cell DCM and fetal bovine serum. Furthermore, quiescent fibroblasts were stimulated by primary tumor cell DCM in the presence of saturating concentrations of fetal bovine serum. These observations support the notion that the active growth-promoting principle in primary tumor cell DCM may not be a serum factor(s).  (+info)

Diphtheria toxin effects on human cells in tissue culture. (6/155046)

HeLa cells exposed to a single sublethal concentration of diphtheria toxin were found to have diminished sensitivity when subsequently reexposed to the toxin. Three cells strains exhibiting toxin resistance were developed. In the cells that had previously been exposed to toxin at 0.015 mug/ml, 50% inhibition of protein synthesis required a toxin concentration of 0.3 mug/ml, which is more than 10 times that required in normal HeLa cells. There appears to be a threshold level of diphtheria toxin action. Concentrations of toxin greater than that required for 50% inhibition of protein synthesis (0.01 mug/ml) are associated with cytotoxicity, whereas those below this concentration may not be lethal. Several established human cell lines of both normal and neoplastic origin were tested for their sensitivity to the effects of the toxin. No special sensitivity was observed with the cells of tumor origin. Fifty % inhibition of protein synthesis of HeLa cells was achieved with diphtheria toxin (0.01 mug/ml) as compared to the normal human cell lines tested (0.03 and 0.5 mug/ml) and a cell line derived from a human pancreatic adenocarcinoma (0.2 mug/ml). A human breast carcinoma cell line showed a maximum of 45% inhibition of protein synthesis. This required a diphtheria toxin concentration of 5 mug/ml. These results suggest that different human cell lines show wide variation in their sensitivity to the toxin.  (+info)

The effects of estrogens and antiestrogens on hormone-responsive human breast cancer in long-term tissue culture. (7/155046)

We have established or characterized six lines of human breast cancer maintained in long-term tissue culture for at least 1 year and have examined these lines for estrogen responsiveness. One of these cell lines, MCF-7, shows marked stimulation of macromolecular synthesis and cell division with physiological concentrations of estradiol. Antiestrogens are strongly inhibitory, and at concentrations greater than 3 X 10(-7) M they kill cells. Antiestrogen effects are prevented by simultaneous treatment with estradiol or reversed by addition of estradiol to cells incubated in antiestrogen. Responsive cell lines contain high-affinity specific estradiol receptors. Antiestrogens compete with estradiol for these receptors but have a lower apparent affinity for the receptor than estrogens. Stimulation of cells by estrogens is biphasic, with inhibition and cell death at concentrations of 17beta-estradiol or diethylstilbestrol exceeding 10(-7) M. Killing by high concentrations of estrogen is probably a nonspecific effect in that we observe this response with 17alpha-estradiol at equivalent concentrations and in the otherwise unresponsive cells that contain no estrogen receptor sites.  (+info)

The effects of glucocorticoids and progesterone on hormone-responsive human breast cancer in long-term tissue culture. (8/155046)

Glucocorticoids, at physiological concentration, inhibit cell division and thymidine incorporation in three lines of human breast cancer maintained in long-term tissue culture. At steroid concentrations sufficient to inhibit thymidine incorporation 50%, little or no effect is seen on protein synthesis 48 hr after hormone addition. All three of these lines are shown to have glucocorticoid receptors demonstrable by competitive protein binding assays. Receptors are extensively characterized in one line by sucrose density gradient analysis and binding specificity studies. Good correlation between receptor-binding specificity and biological activity is found except for progesterone, which binds to glucocorticoid receptor but is noninhibitory. Cross-competition and quantification studies demonstrate a separate receptor for progesterone. This receptor has limited binding specificities restricted largely to progestational agents, whereas the glucocorticoid receptor bound both glucocorticoids and progesterone. Two other human breast cancer lines neither contain glucocorticoid receptor nor are inhibited by glucocorticoids. It is concluded that in some cases glucocorticoids can directly limit growth in human breast cancer in vitro without requiring alterations in other trophic hormones.  (+info)

N2 - Microglial activation has been implicated in the recognition and phagocytic removal of degenerating neurons; however, this process must be tightly regulated in the central nervous system, because prolonged activation could damage normal neurons. We report that mouse primary-cultured microglia, which are destined to die within a few days under ordinary culture conditions, can live for more than 1 month when kept activated by lipopolysaccharide (LPS) treatment. Primary-cultured microglia treated with sublethal doses of LPS remained viable, without any measurable increase in apoptotic or necrotic cell death. LPS-treated microglia had an arborescent shape, with enlarged somata and thickened cell bodies. Although the amount of intracellular ATP in ...

The present study was undertaken to elucidate different requirements for CD2-mediated activation of naive (CD45RO-) and memory (CD45RO+) CD4+ T cells. A mitogenic combination of anti-CD2 (anti-T11(2) and anti-T11(3] mAbs could effectively induce the proliferation of memory CD4+ T cells even in the absence of monocytes. In marked contrast, naive CD4+ T cells did not disclose any proliferative responses to anti-CD2 mAbs, when monocytes were absent in culture. This differential responsiveness of naive and memory CD4+ T cells appeared to be related largely to a difference in IL-6-producing ability between both populations. IL-6 among monocyte-derived cytokines could correct unresponsiveness of naive CD4+ T cells to anti-CD2 stimulation. Unlike naive CD4+ T cells, memory CD4+ T cells produced IL-6 by themselves, with its mRNA being expressed on anti-CD2 stimulation. Anti-IL-6R mAb significantly inhibited proliferation of memory CD4+ T cells seen in the anti-CD2-stimulated cultures without monocytes, ...

We offer 4 types of normal human primary cells in the adipose cell system including endothelial cells, preadipocytes and mesenchymal stem cells.
Growth Requirements. The culture media used for cell cultures are generally quite complex, and culture condition widely varies for each cell type. However, media generally include amino acids, vitamins, salts (maintain osmotic pressure), glucose, a bicarbonate buffer system (maintains a pH between 7.2 and 7.4), growth factors, hormones, O2 and CO2. To obtain best growth, addition of a small amount of blood serum is usually necessary, and several antibiotics, like penicillin and streptomycin are added to prevent bacterial contamination.. Temperature varies on the type of host cell. Most mammalian cells are maintained at 37oC for optimal growth, while cells derived from cold- blooded animals tolerate a wider temperature range (i.e. 15oC to 26oC). Actively growing cells of log phage should be used which divide rapidly during culture.. Process to obtain primary cell culture. Primary cell cultures are prepared from fresh tissues. Pieces of tissues from the organ are removed aseptically; which are ...

Given the fact that IL-10 is especially produced by immune cells, we investigated whether the same is true for the other members of the IL-10 family, IL-19, IL-20, IL-22, mda-7, and AK155, and, if so, to what extent. Monocytes, NK cells, B cells, and T cells from the blood of different healthy donors were investigated for their possible constitutive, as well as activation-induced, expression of these molecules. For this purpose, cells were cultured in a kinetic approach in the absence and presence of the typical cell-specific stimuli LPS (monocytes), IL-2/IL-12 (NK cells), fixed S. aureus (B cells), and anti-CD3 mAb coated on the culture vessel (T cells), respectively, for 2, 6, and 18 h. The activation state of control and stimulated cells was verified by the absence and presence of high TNF-α production in the monocyte culture and elevated expression of different activation markers, e.g., CD69, on the lymphocyte populations (Fig. 1⇑A). Gene expression of the IL-10 family members was ...
Ongoing advances in quantitative molecular- and cellular-biology highlight the need for correspondingly quantitative methods in tissue-biology, in which the presence and activity of specific cell-subpopulations can be assessed in situ. However, many experimental techniques disturb the natural tissue balance, making it difficult to draw realistic conclusions concerning in situ cell behaviour. In this study, we present a widely applicable and minimally invasive method which combines fluorescence cell labelling, retrospective image analysis and mathematical data processing to detect the presence and activity of cell subpopulations, using adhesion patterns in STRO-1 immunoselected human mesenchymal populations and the homogeneous osteoblast-like MG63 continuous cell line as an illustration.. Adhesion is considered on tissue culture plastic and fibronectin surfaces, using cell area as a readily obtainable and individual cell specific measure of spreading. The underlying statistical distributions of ...

The purpose of the present investigation was to explore the effects of well-defined flow conditions on the activity of tissue factor (TF) expressed on the surface of cultured rat vascular smooth muscle cells. Cells were cultured to confluence on Permanox brand slides and stimulated to express TF by a 90 min incubation with fresh growth medium containing 10 percent calf serum. The stimulated cells were then placed in a parallel plate flow chamber and perfused with Hanks Balanced Salt Solution containing factor VIIa, factor X (FX), and calcium. The chamber effluent was collected and assayed for factor Xa (FXa) and the steady-state flux of FXa was calculated. The flux values were 68.73, 94.81, 139.75, 138.19, 316.82, and 592.92 fmole/min/cm2 at wall shear rates of 10, 20, 40, 80, 320, and 1280 s−1 respectively. The FXa flux depended on the wall shear rate to a greater degree than predicted by classical mass transport theory. The flux at each shear rate was three to five times less than that ...

Vascular smooth muscle (VSM) cell proliferation contributes to the pathogenesis of atherosclerosis, restenosis after angioplasty and vein graft disease. The regulation of genes involved in VSM cell proliferation, particularly by naturally occurring inhibitors, is therefore of some importance. We have investigated the role of the c-myc proto-oncogene in growth arrest of exponentially proliferating rat VSM cells, following mitogen withdrawal, treatment with heparin (50 micrograms/ml), interferon-gamma (IFN-gamma) (100 i.u./ml), or the cyclic nucleotide analogues, 8-bromo-adenosine-3′5′-cyclic monophosphate (8-Br-cAMP; 0.1 mM) and 8-bromoguanosine-3′5′-cyclic monophosphate (8-Br-cGMP; 0.1 mM). Growth arrest was accompanied by down-regulation of c-Myc protein and mRNA following treatment with all inhibitors. Serum withdrawal or IFN-gamma treatment suppressed c-myc expression by more than 50% within 2 h, and this occurred throughout the cell cycle. Platelet-derived growth factor, epidermal ...
The concept of arterial SMC heterogeneity has gained wide acceptance in the last years.1 2 33 The distinct phenotypes of arterial SMCs have been mainly identified in vitro,4 5 6 7 8 9 10 11 12 13 14 15 16 suggesting that specific features of SMC populations arise and are maintained in the particular environment of cell culture. Hence, it was of interest to investigate whether in vitro SMC phenotypes are preserved when SMCs are placed back in an in vivo environment. For this purpose, we have implanted 2 SMC populations exhibiting distinct levels of differentiation in vitro into the rat carotid artery submitted to endothelial injury.24 25 The implanted SMCs were marked with PKH-26, a lipophilic cell membrane linker that is halved with each cell division but is not lost from the cell membrane.34 Our results show that the 2 implanted populations essentially retain for 20 days in vivo the phenotype that they specifically exhibited in vitro.. Spindle-shaped and epithelioid rat SMC populations have ...

Full Text - Hydrogen peroxide (H2O2) induces oxidative injury to human osteoblasts. The expression and potential function of circular RNA HIPK3 (circHIPK3) in H2O2-treated human osteoblasts were tested. We show that H2O2 significantly downregulated circHIPK3 in OB-6 cells and primary human osteoblasts. Furthermore, circHIPK3 levels were decreased in the necrotic femoral head tissues of dexamethasone-treated patients. In OB-6 osteoblastic cells and primary human osteoblasts, forced overexpression of circHIPK3 by a lentiviral construct alleviated H2O2-induced viability reduction, cell death and apoptosis. Contrarily, circHIPK3 silencing by targeted shRNA potentiated H2O2-induced cytotoxicity in OB-6 cells and primary human osteoblasts. Moreover, circHIPK3 downregulation by H2O2 induced miR-124 accumulation in OB-6 cells and primary human osteoblasts. On the contrary, miR-124
Many studies have shown that TRAIL is a potent apoptosis inducer in malignant cells, whereas its role in normal cell physiology is much less well understood.1 We have demonstrated here that both aortic endothelial cells and HUVECs exhibit a similar pattern of surface TRAIL-R expression. Moreover, in vascular endothelial cells, TRAIL stimulates the phosphorylation of the serine/threonine kinase Akt in a manner dependent on PI3K activation.14 The ability of TRAIL to activate the antiapoptotic PI3K/Akt pathway in endothelial cells is a completely new and unexpected finding, also in consideration of the large number of studies underlining the proapoptotic activity of TRAIL, at least in malignant cells.1,4,5 It should be underlined that the PI3K/Akt pathway is of central importance in endothelial cell biology, conferring survival to endothelial cells in response to angiogenic cytokine stimulation, fluid shear stress, and matrix attachment signals. This pathway is essential also for endothelial cell ...
TY - JOUR. T1 - Activation of caspase-8 and Erk-1/2 in domes regulates cell death induced by confluence in MDCK cells. AU - Chang, Yung Heng. AU - Lin, Hsi Hui. AU - Wang, Yang Kao. AU - Chiu, Wen Tai. AU - Su, Hsiao Wen. AU - Tang, Ming Jer. PY - 2007/4/1. Y1 - 2007/4/1. N2 - Under normal culture conditions, cells adhere to culture dish, spread out, proliferate, and finally cover all areas and reach confluence. During the confluent stage, cell proliferation ceases and differentiation is enhanced. Meanwhile, cell death also appears as the monolayer confluence proceeds. To delineate the mechanism of cell death induced by the confluent process, we employed Madin-Darby canine kidney (MDCK) cells. When approaching confluence, MDCK cells exhibited increase the levels of caspase-2 and enhanced the activity of caspase-8. Using various caspase inhibitors to block apoptosis, we found that only z-VAD-fmk and z-IETD-fmk can inhibit confluent cell death, indicating that confluent cell death is mediated by ...
In the present article, we compared the antiangiogenic activity of trans- and cis-resveratrol on endothelial cells of different origin activated by endogenous or exogenous stimuli. The results indicate that trans-resveratrol affects endothelial cell proliferation and various cell proliferation-independent aspects of the angiogenesis process, including endothelial cell sprout formation, collagen gel invasion, and morphogenesis. Thus, trans-resveratrol acts as an angiostatic molecule on multiple targets of the angiogenic process. In all the assays, the cis stereoisomer exerted only a limited effect, if any. In keeping with the in vitro observations, trans-resveratrol was more effective than the cis isomer in inhibiting angiogenesis and tumor growth in vivo.. The molecular bases of the antiangiogenic activity of resveratrol are poorly understood (16). trans-Resveratrol is endowed with a significant antioxidant and anti-inflammatory activity (8, 9). However, no direct relationship exists between the ...
TY - JOUR. T1 - Recombinant murine and human IL 1α bind to human endothelial cells with an equal affinity, but have an unequal ability to induce endothelial cell adherence of lymphocytes. AU - Thieme, T. R.. AU - Hefeneider, S. H.. AU - Wagner, C. R.. AU - Burger, D. R.. PY - 1987/1/1. Y1 - 1987/1/1. N2 - Consistent with the reports of others, we have demonstrated that human peripheral blood lymphocytes adhere to cultured human umbilical vein-derived endothelial cells (EC) in vitro. In our studies adherence was increased twofold to threefold by a 6-hr preincubation of the EC with IL 1. Recombinant human IL 1α induced a maximal adherence response at less than 1 U per 2 x 104 EC. In contrast, recombinant murine IL 1α was found to be 250- to 1250-fold less active in the adherence assay, based on units of IL 1 activity defined by the murine thymocyte proliferation assay. Moreover, when EC were preincubated with excess murine IL 1, no inhibition of the adherence-inducing effect of human IL 1 was ...
The effects of interferons (IFNs) on lymphocyte adhesion to cultured human vascular endothelial cells (EC) were investigated using an in vitro assay. Endothelial cells obtained from umbilical vein were first cultured at a low density with a conditioned medium (CM) from 12-O-tetra decanoylphorbol 13-acetate-concanavalin A (TPA-Con A) stimulated human peripheral blood lymphocytes (PBL), or with recombinant (r) gamma interferon (IFN-gamma) or r alpha interferon (IFN-alpha), and then were incubated with freshly isolated PBL. Natural IFN-gamma in the TPA-Con A CM and rIFN-gamma (12.5-500 U/ml) induced major histocompatibility complex-class II antigens (HLA-DR, HLA-DP, and HLA-DQ) and significant lymphocyte adhesion to the EC, whereas rIFN-alpha did not. The lymphocyte adhesion to the EC and the expression of DR antigens on the EC were well correlated in terms of both kinetics and the dose-response pattern of rIFN-gamma. When EC expressing I region associated (Ia) antigen were preincubated with ...
The fully sequenced pCERI is transformed into E.coli BL21 and E.coli Nissle 1917 that are used for the characterization of our regulatory system. The expression efficiency of the genes of interest is characterized by a fluorescence-based assay (Results) Overnight cultures of both recombinant strains are inoculated with single colonies. The overnight cultures are diluted with LB-Amp to an OD of 0.02. 200 μ of the dilutions are pipetted in microtiter plates and incubated at 37 °C in the plate reader. Every 15 minutes mRFP fluorescence (Ex. 584 nm, Em. 607 nm), CFP fluorescence (Ex. 439 nm, Em. 476) and OD600 is measured over a period of 13 h. The measured RFU (relative fluorescence unit) is either blotted against time or against OD600 to evaluate the expression behavior of pCERI. Additionally several samples are either induced with 0.1 -50 nM of 3OC6-HSL and 0.1-100 nM of C8-HSL to explore putative advantages of higher HSL-synthesis, that might be possible by positioning each HSL-synthase, ...

Choice of AMP 100 versus AMP 50 - posted in Molecular Cloning: Ok, i know the main difference is the amp concentration. But i wonder if it matters that i use amp 50 for overnight culture versus amp 100 for overnight culture.
I am studying the differentiation of leukemic cells along the monocytic lineage using calcitriol as differentiative agent and others vitamins as possible stimulating compounds on differentiation. In my work I have used HL-60 cells as in vitro culture cells but now I have some problems because these cells have changed their response and develop expontaneous differentiation in normal culture conditions. Now, I am thinking on NB4 cells as a better cell line to study differentiation. I have ask some information to cell banks as ATCC and ECA but they dont have this cell line. Could anybody tell me if anyone can send me this cell line?, I have very gratefull if anyone could send me HL-60 cells too. Waiting positive responses and acknowledging in advance.

One group of projects in the lab concerns "co-receptors", cell-surface molecules that regulate the interaction between soluble growth factors and their cell-surface receptors. We have identified a novel co-receptor for BMPs (bone morphogenetic proteins) and are studying the roles of Heparan Sulfate Proteoglycans (HSPGs) as co-receptors for a variety of growth factors, including those that drive tumor development and pattern the developing nervous system. We have used "knockout" technology to generate mice that are mutant for particular HSPGs, and are also working with mice that are mutant for some of the biosynthetic enzymes required to make HSPGs. We are also using modeling approaches to understand how HSPGs influences the kinetic parameters of growth factor-receptor interaction ...
How would the cells respond to Aβ? Mancuso injected 5 μL of 10 μM synthetic oligomers into the mouse brain ventricles eight to 10 weeks after transplanting the human microglia. In reaction to this insult, endogenous mouse microglia shifted their transcriptomes sequentially from homeostatic to cytokine responsive, to activated, with the latter partially overlapping with disease-associated microglial (DAM) signatures described previously (Jun 2017 news). Human microglia in the mice underwent a transcriptional transformation as well, but analysis of more than 10,000 orthologous genes indicated poor correlation between human and mouse microglial responses. Of 207 differentially activated genes, 112 were up in human but not mouse microglia; they included GWAS hits BIN1 and PICALM. "We saw that human microglia responded very differently to Aβ oligomers. This emphasizes the need to look specifically at human cells in the context of AD," said De Strooper.. Blurton-Jones and colleagues took a ...

Recent evidence supports a strong role for immune suppression in facilitating cancer progression. Transforming growth factor beta (TGFß) regulates a diverse array of biological events, including neoangiogenesis, stromal formation, and immune responses. Both TGFß and a small molecule inhibitor of TGFßR-1, LY364947, were effective regulators of these processes in vitro. Using quantitative RT-PCR and fluorescence imaging, TGFß increased collagen production by pancreatic stellate cells while addition of LY364947 suppressed production below basal levels. Endothelial cell proliferation, measured as a function of endothelial tube formation in Geltrex® matrix, was similarly increased by TGFß and reduced to basal levels by LY364947. To explore the in vivo effects of these molecules, LY364947 was encapsulated in liposomes to encourage tumor accumulation and to avoid administration of DMSO vehicle. Liposomes were prepared with a molar ratio of 6:3:1 1,2-dipalmitoyl-sn-glycero-3-phosphocholine ...
