  • Angiogenesis is a process in which new capillaries are formed from existing microvascular vessels.
  • angiogenesis occurs normally, embryonic development, tissue regeneration and wound healing, and periodic changes in the female genital system are called corpus luteum. Is a developmental stage, and in this case, it is strictly controlled (Folkman J et al., Int. Rev. Exp. Pathol. , 16, pp 207-248, 1976).
  • vascular endothelial cells grow very slowly and do not divide relatively well compared to other types of cells.
  • the angiogenesis process is generally caused by stimulation of angiogenesis factors, resulting in the formation of lumen due to the degradation of the basal membrane, proliferation, proliferation, and differentiation of vascular endothelial cells due to proteases. Consists of being generated.
  • angiogenesis there are diseases caused by angiogenesis that is not controlled autonomously and grows pathologically.
  • Diseases related to angiogenesis in pathological conditions include hemangioma, angiofibroma, angioplasty and cardiovascular diseases such as atherosclerosis, angiogenesis, and edema sclerosis.
  • Eye diseases caused by angiogenesis include corneal graft angiogenesis and angiogenesis. Glaucoma, diabetic retinopathy, corneal disease caused by neovascularization, spot degeneration, pterygium, retinal degeneration, posterior capsular fibrosis, granular conjunctivitis and the like.
  • Chronic inflammatory diseases such as arthritis, psoriasis, capillary dilatation, purulent granulomas, seborrheic dermatitis, dermatological diseases such as acne, Alzheimer's and obesity are also associated with angiogenesis, and cancer growth and metastasis necessarily depends on angiogenesis (D'Amato RJ et al., Ophthalmology, 102 (9), pp1261-1262, 1995; Arbiser JL, J. Am. Acad. Dermatol., 34 (3), pp486-497, 1996; O'Brien KD et al. Circulation, 93 (4), pp 672-682, 1996; Hanahan D et al., Cell, 86 , pp 353-364, 1996).
  • Angiogenesis plays an important role in the growth and metastasis of cancer cells.
  • Tumors are supplied with nutrients and oxygen for growth and proliferation through neovascularization, and new blood vessels that penetrate the tumors allow cancer cells to metastasize by giving the metastasizing cancer cells an opportunity to enter the blood circulation (Folkman and Tyler, Cancer Invasion and metastasis , Biologic mechanisms and Therapy (SB Day ed.) Raven press, New York, pp 94-103, 1977; Polverini PJ, Crit. Rev. Oral. Biol. Med. , 6 (3), pp 230-247, 1995).
  • the main cause of death of cancer patients is metastasis, and the current metastasis of cancer does not contribute to the survival of cancer patients.
  • diabetic retinopathy is a complication of diabetes, in which capillaries in the retina invade the vitreous body and eventually become blind.
  • Psoriasis which is characterized by red spots and skin, is also a chronic proliferative disease of the skin. It does not heal and involves pain and malformations. In normal cases, keratinocytes proliferate once a month, whereas psoriasis patients proliferate at least once a week. This rapid proliferation requires a lot of blood supply and angiogenesis is inevitably active (Folkman J, J. Invest. Dermatol., 59, pp 40-48, 1972).
  • Inflammatory bowel disease one of the other representative diseases of inflammatory diseases, is a term used to refer to diseases that cause inflammation of the intestinal ulcerative colitis, Crohn's disease, Behcet's disease, intestinal tuberculosis, amoeba enteritis, radiation enteritis, and drug-induced enteritis.
  • inflammatory bowel disease refers to ulcerative colitis and Crohn's disease, which are chronic idiopathic inflammatory diseases.
  • Ulcerative colitis is a disease in which mucous membranes or ulcers form continuously on the mucous membrane of the colon. Bloody stools, mucosal stools, diarrhea and abdominal pain occur, and in severe cases, systemic symptoms such as fever, weight loss, and anemia appear. .
  • Crohn's disease is a condition in which lesions such as ulcers are discontinuously occurring in any part of the digestive tract from the mouth to the anus. In addition to abdominal pain, diarrhea and bloody stools, in severe cases, fever, bleeding, weight loss, and general malaise , Anemia and other symptoms appear. Ulcerative colitis and Crohn's disease are both chronic refractory diseases that temporarily improve symptoms and then recur. The pathogenesis of these diseases is pointed out that environmental factors such as genetic factors, immune abnormalities, and meals are involved, but the cause is still unclear.
