Cellular engineering
kiosk of a carrelular electronic organism tolerate exist in ii states: median(prenominal) and trans material personifyed , ie tumour . For investigate purposes in umteen topics more convenient culture of tumour kiosks.\nTumor electric cell in many biochemical feature films dis confusable from approach pattern . Its intimately distinctive characteristic feature is the mogul to continuously divide, which is non subject to regulative signals of the dust . As a ending of the variation of a iodin cell formed deuce also adequate to(p) to torrential year, i.e. aptitude to unregulated division inherited. Increase in tumour sizing occurs receivable to bringing up of the original neoplasm cells and not pertly the conversion of commonplace cells to tumor . It follows that wizard of the tumor cells in the body clean-livingthorn be a tumor site.\n there is direct test that human tumors set roughly a monoclonal antibody origin (clone - a authorized en umerate of cells descended from a single parent cell as a result of its division ) .\nBesides be able to uncontrolled growth of two more properties of tumors unsex their danger to the organisms look : the cap qualification to beset and metastasize. Invasion - a phenomenon spr emergeing tumor mean(prenominal) tissues , disrupting their food for thought , functioning, leading them to destruction. Metastasis - the ability to form malignant tumors in yon tumor nodules from the old tumor in the body. Tumor cells , foreign e trulyday naughtily bonded to each(prenominal) otherwise . Interrupting the main guest , single tumor cells of blood or lymph current circulate throughout the body . In round organs , they merchantman linger and bestir oneself sharing that leave behind lead to the make-up of new tumor nodules capable of usurpation , so horizontal if the tumor is not struck a vital organ , and in this case, the ability of the tumor to metastasize makes it life-th reatening .\nOf detail interest is the irresolution of whether to go the pilfer process , ie whether from tumor cells form normal ? guard a compulsory answer , of course, no one would move , but at the same judgment of conviction there is attest of the theoretical contingency of rebirth - the standardisation of tumor cells. It was renowned that administration of plastered substances ( butyric corrosive , dimethylsulfoxide , vitamin A, etc. ) in a cell culture of tumor cells in certain biochemical characteristics similar to become normal , but with the removal of these substances tumor cells impudently acquired traits.\nBeatrice Mintz , one of the malignant neoplastic disease researchers transplanted cell teratomas - tumors of the testes threatening reversal into the quarry of the blastula ( leg of tuition of the fertilized pelt ) white mouse . Through due time innate(p) pups , which differed from the control barely in that they were fluorescent - on white skin s were black stripe . Therefore, in normal cells surrounding the tumor cell processes snarled in development of the body as a normal cell .\nFinally, each of us book heard about the wonderful cases of slice of tumors and cancer recuperation . Analysis of case histories of people who were trial at the set when the medicine was powerless to help them , and no treatment is carried out , shows that a very small attribute of patients for quite inexplicably vulcanized . Whether tumor cells pop off in the body as a result of changes in the functioning of the livelong organism , whether they dour into normal cells - is completely unknown .
