Description
Technical field
The present invention relates to people's tongue squamous cell cancer cell technology field, particularly, relate to a kind of Chinese's tongue squamous cell cancer clone CTSC-1 and establishment method thereof.
Background technology
The morbidity of 1.1 tongue squamous cell cancers and prognosis
Tongue cancer is modal oral squamous cell carcinoma, often occurs in front 2/3 place of tongue.Tongue cancer is occurred frequently in South East Asia, and with India, for the highest, Annual occurence rate reaches 9.4/100 ten thousand.Recent study demonstration, in world wide, the total incidence of tongue cancer progressively improves, and has the trend of rejuvenation.Due to the histological characteristic of its happening part and the biological characteristics of tongue cancer, tongue cancer makes patient's tongue limitation of movement, and difficulty causes swallowing, speaks, takes food.In addition, tongue cancer easily shifts, and prognosis is poor.
The progress of 1.2 tumor stem cells
1.2.1 the proposition of tumor stem cell theory and development
Traditional concept thinks, tumour be a group by somatic mutation, obtain the cell composition of unlimited multiplication capacity, but the experiment of mouse tumorigenesis and body outer clone formation experimental result show, be not that all tumour cells can be bred.Illustrate that tumour is not the individuality of a homogeneous, it has heterogeneity, has different cell subsets in tissue.In tumor tissues, may some have the cell of stem cell characteristic, this cell type is called as tumor stem cell (cancer stem cell, CSC).
Tumor stem cell theory is proved in leukemia, Lapidot in 1994 etc. are utilized and in cell surface marker CD34+CD38-and mouse tumorigenesis model, are isolated people's acute myeloblastic leukemia (Acutemyeloid leukemia by FACS, AML) stem cell, subsequently, the discoveries such as Bonnet only have CD34+/CD38-leukemia cell can be in non-diabetic severe severe combined immunodeficiency (nonobese diabetic/severe combinedimmunodeflcient, NOD/SCID) Mice Body tumorigenesis.2003, Clarke etc. applied to tumor stem cell theory in solid tumor for the first time, and they have confirmed this viewpoint in mammary cancer, CD44+CD24-/low cell only need 100 just can tumorigenesis.Afterwards, research is found also can isolate tumor stem cell in the cancers such as cerebral tumor, liver cancer, lung cancer such as glioblastoma multiforme, has supported this theory.2006, AACR (American As sociation for Cancer Research) made definition to tumor stem cell: in tumour, have self-renewal capacity, and can produce the cell of heterogeneous tumour cell.It has three large characteristics: 1, differentiation capability: tumor stem cell is served as the role who forms and break up all types of tumour cells in tumour, in Tumor Growth, constantly supplements required all kinds of tumour cells.2, self-renewal capacity: generate a part with own identical, there is the cell of propagation, expansion and differentiation potential, thereby maintain the homeostasis of stem cell.3, Steady-State Control ability: the differentiation of adjusting and balance tumour, according to the stimulation of environment, tumour is made to regulation and control.
1.2.2 research and the application thereof of tumor stem cell in oral carcinoma
In the same cancer kitchen range of oral carcinoma tissue, include the cancer cells of different differentiation degrees, different steps.Studies confirm that, in incidence squamous cell cancer, exist a group to there is self, multi-lineage potential and have the cancer cells of tumorigenesis ability.Tumor stem cell is mostly in dormant state, insensitive to Radiotherapy chemotherapy, it is the root that after causing performing the operation, tumour easily recurs, resistance is strong, refractory is healed, the proposition of tumor stem cell theory can make the target for the treatment of from tumour global transfer to tumor stem cell, proposes the comprehensive therapy strategy combining for cancer cells and tumor stem cell.The research of tumor stem cell is also for the research of tumour has brought a new thinking.
The foundation of 1.3 clones
Setting up tumor cell line is that research tumour causes the important link in pass.Clone is widely used in each research field of biology.It refers to that directly separation and Culture goes out cell from the tissue of organism, for follow-up study provides a kind of method of stable cell lines.Clone is growth, metabolism, the modulating properties of research specific cells, cell and cell-cell interaction, and the interactions of cell and matrix etc. are research material effectively.The first strain continuous cell line of the mankind is the cervical cancer cell system (Hela) being set up by George Otto Gey laboratory nineteen fifty-one, the foundation of this strain clone is the milestone of human body cell vitro culture, Hela cell has advanced the process of many research fields such as cell, gene, virus, vaccine, has also deepened the understanding of people to tumour: find the various characteristics of tumour, reason and process, the screening cancer therapy drug etc. of research tumor development.Except the developing of the research characteristic of cell itself and cancer, be also applied to the research field of heredity, immunity, differentiation, growth.In addition, many enterprises can also utilize cell to produce the various factors, albumen etc. both at home and abroad.The widespread use of cell has promoted the flourish of cytobiology.
Former culture mainly contains mechanical process and enzyme digestion.Mechanical process is mainly to utilize physics to shear, and directly tissue is shredded, and then these is organized to the method for fritter adherent culture.Thereby enzyme digestion is the suitable enzymatic lysis tissue of application isolate unicellular, directly suspension or the method for adherent culture.Mainly contain for the enzyme digesting: trypsinase, collagenase, pronase, Unidasa etc.
The qualification of squamous cell cancer clone has the following aspects: 1, pathological section qualification: the World Health Organization (WHO, 2005) is divided into high, medium and low three grades according to cell and nuclear polymorphism, cell fission state, angling degree etc.Differentiated squama cancer is similar with normal tesselated epithelium, angling obviously, nuclear fission mutually less, cell and nucleus polymorphism not obvious; Middle differentiated squamous-cell carcinomas angling is more rare, nuclear fission mutually many, cell polymorphism is obvious; Low differentiated squamous-cell carcinomas has a large amount of nuclear fission phases, cell polymorphism is obvious, angling is very rare; 2, cellular form: be generally polygon Epithelial, nuclear-cytoplasmic ratio is high, the clear number of kernel is more, after cell arrangement is tight, is paving stone sample; 3, iuntercellular desmosome connects: on the film between flanking cell, have a border circular areas, responsible intercellular connection, communication, opposing external force are pullled, desmosome is more common in epithelium, the stratified squamous epithelium iuntercellular that skin, oral cavity, oesophagus etc. are located is more, can be destroyed by trypsinase, collagenase and Unidasa, under Electronic Speculum, mostly visible macula densa and Intermediate Filaments, be keratin filament in epithelial cell; 4, molecular marker: be mainly cytokeratin (cytokeratin, CK), be expressed in specifically epithelial cell, it is the Intermediate Filaments proteinoid that forms epithelial cell inner cell skeleton, have 20 kinds, CK1-9 is meta-alkalescence or neutral II type Keratin sulfate, and CK10-20 is the I type Keratin sulfate of slant acidity, these Keratin sulfate General Expressions are in specific organ or tissue, and CK8, CK18, CK19 are often expressed in simple epithelium.The above-mentioned biological characteristics that is characterized as the newly-established tongue squamous cell cancer clone of analysis of squamous cell cancer provides theoretical foundation.
The first strain tongue squamous cell cancer Establishment of Cell Line was in 1981, and by Japan Report, this strain clone fails to make mouse tumorigenesis.Then nineteen eighty-three has been set up a strain tongue cancer Tca8113 at China's Shanghai report, and 1995 have set up a strain tongue cancer cells PWH-S1 at China's Hong Kong report.Existing at Americantype culture collection(ATCC) in tongue cancer cells have 5 strains, be respectively SCC-15, SCC-4, SCC-25, SCC-9, CAL27, are all eighties in 20th century, rarely have afterwards report.
The biological characteristics of different Human Tongue Carcinoma Lines can there are differences, the method that this species diversity comes from patient itself and receives treatment.The degree of differentiation of some tongue cancer is low, and grade malignancy is high; The degree of differentiation of some tongue cancer is high, and grade malignancy is low.Some patient accepts chemotherapy in the preoperative, and therefore postoperative obtained cell has higher resistance.The existence of this species diversity just, makes our diversity to tongue cancer and complicacy have more understanding, and the tongue cancer cells there are differences just becomes research tongue cancer and occur effective external model of development.
