Angiogenesis or formation of new blood vessels from preexisting vasculature is a key process in some physiological conditions such as wound healing, growth, and action of female reproductive organs. Moreover, disturbance of the mechanisms of physiological angiogenesis has a role in pathogenesis of some diseases in the form of overproliferation of blood vessels such as cancers, psoriasis, arthri...

Background: Angiogenesis initiated by cancerous cells is the process by which new blood vessels are formed to enhance oxygenation and growth of tumor. Objective: In this paper, we present a new multiscale mathematical model for the formation of a vascular network in tumor angiogenesis process. Methods: Our model couples an improved sprout spacing model as a stochastic mathematical model of spro...

background: angiogenesis is an important process in various physiologic and pathologic states. the most significant stimulator of angiogenesis is vascular endothelial growth factor (vegf). in contrast, vasohibin1 acts as an angiogenesis inhibitor which specifically inhibits new vessels formation. the aim of the present study was cloning and expression of vasohibin1 gene in e. coli as well as pu...

introduction: acute myeloid leukemia is a malignant transformation of hematopoietic tissue, bone marrow infiltration of undifferentiated cells known as blasts that interfere with the production of normal cells. vascular endothelial growth factor (vegf) is persistently secreted from myeloid cells and high levels can be detected in patients' serum. methods: twenty-one aml patients, who were chemo...

single-gene disorders occur when mutation in a gene causing alteration of gene function while in multifactorial disorders, mutations occur in multiple genes, and these are usually coupled with environmental causes. in addition, in a multifactorial disorder such as diabetes, the complication is under the influence of different genes. for example, in diabetic retinopathy many genes are involved i...

thirty six wistar albino rats with implant induced endometriosis were randomly divided into six groups of six animals each. the rats in the first group received nothing and were euthanized at day 21. in the second group, rats received nothing and were euthanized at day 36. the third group received atorvastatin (atv; 5 mg kg-1 per day, orally) until 21 days from induction of endometriosis, and t...

background: marine natural products contain a wide range of bioactive compounds with therapeutic properties that have revealed crucial properties in the treatment of some diseases. some of these compounds have recently received considerable attention for drug discovery. in this study we examined the anti-angiogenic effect of saponin isolated from holothuria leucospilota (sea cucumber) through e...

• 3D-exos promote angiogenesis in vivo. exert their function via activation of HMGB1/AKT signaling pathway. have a superior ability HUVEC proliferation, migration, and tube formation. Angiogenesis is an essential step tissue engineering. MSC exosomes play important role angiogenesis. Functional biomolecules vested by the culture microenvironment can be transferred to recipient cells affects eff...

the basic pathogenic step in the process of tumor growth, invasion and metastasis is tumor-induced angiogenesis. the aim of this study was to evaluate the angiogenesis in colorectal carcinoma by microvascular density (mvd) determination with ihc (immunohistochemistry) method and to determine if and how angiogenesis correlates with clinicopathologic parameters. sixty two archival, paraffin embed...
