Description
Technical field
The utility model relates to a kind of device of a kind of animal tissues vitro culture and cell cultures.
Background technology
Angiogenesis (angiogenesis) is to germinate and generate the process of neovascularity from existing blood vessel.Angiogenesis is found in physiological status, as the normal growth of embryo's formation and tissue.In addition, angiogenesis is common in some pathologic condition, as tumour, wound healing etc.Angiogenesis has important value in the research of tumour, studies confirm that at present new vessel not only can increase knurl body, and makes tumour more easily occur to shift and diffusion, finally causes serious consequence.The angiogenesis of research tumour contributes to understand that malignant tumour occurs, development, invasion and attack and the biological characteristics that shifts, and has important theory significance and clinical value to illustrating mechanism, estimating prognosis and carrying out antiangiogenic therapy etc.
Set up both at home and abroad the model of many research new vesseles, external model is based on endotheliocyte, on supported matrix, to cultivate the principle foundation that can form luminal structure, as cell or tissue culture model.Body inner model is to study in animal body angiogenesis, as corneal vascularization model, and chick chorioallantoic membrane angiogenic growth model and polymkeric substance planting model.
Corneal vascularization model is that somatomedin is expelled on cornea, or is added in the pouch that cornea upper cut forms, by slit lamp microscope observation sinuys venosus sclerae plexus vasculosus to the situation of growing in cornea.Corneal test operation technique difficulty is large, and operation is also unavoidable afterwards exists inflammatory reaction, and the blood vessel generating is irregular, is difficult to quantitatively.
Chick chorioallantoic membrane angiogenic growth model (CAM) is that medicine is added to carrier as on gelfoam, methylcellulose gum, cellulose mixture filter membrane or filter paper, is placed on and windows on the chorioallantoic membrane exposing, and observes angiogenic growth situation on chorioallantoic membrane after three days.CAM model is applicable to large-scale medicine screening, but the blood vessel network of CAM itself makes newly-generated blood vessel be difficult to identification, and starts there is inflammatory reaction in 7 to 8 days, has hindered the resolution of new vessel.
Polymkeric substance planting model, conventional matrigel or sponge.Matrigel method is that matrigel is expelled in mouse or rat body, and temperature raises and makes matrigel solidify to form embolus.After 7 days, with histochemical method or Immunohistochemical Method, detect the blood vessel situation of embolus of growing into, or detect content of hemoglobin in embolus.The shortcoming of this method is that matrigel is expensive, analyzes more consuming time.
In external model cell culture model be by endothelial cell seeding in having overlay the culture dish of collagen or scleroproein, matrigel, observe the capillary vessel spline structure that endotheliocyte forms in the plane.This model manipulation is simple, can show cell by dormancy the process to blastogenesis, but because cell does not grow from existing blood vessel, can not simulate real angiogenesis completely.
Organize models is embedded in matrix as cultivated in the mixture of the scleroproein of collagen gel, plasma clot, purifying, matrigel or these several albumen by explant as aortic annulus, observes the endotheliocyte growing from inner membrance and to surrounding, form capillary vessel spline structure in gel.The condition of aortic annulus modeling more approaches internal milieu, and it has comprised non-endotheliocyte around, as smooth muscle cell and pericyte, also has matrix support.In addition, endotheliocyte is not the cell going down to posterity, and also not in the multiplicative stage, this more can represent the real conditions of the interior angiogenesis of body of current discovery.Therefore, aortic annulus model is comparatively desirable model of angiogenesis, is most widely used detection method in current angiogenesis research.
When research the Molecular Biology Mechanism, sometimes need cell to carry out separation and evaluation, and observation of cell form, but above-mentioned these models all can not reach unicellular research, also can not realize single celled separation.And utilize these models new life's blood vessel, structure is three-dimensional, be difficult to observe clearly with microscope.
Summary of the invention
The shortcoming existing in order to overcome prior art, the purpose of this utility model is on the basis of aortic annulus model, to invent a kind ofly can clearly observe the individual cells of new vessel and to the unicellular instrument that carries out separate study.
In order to achieve the above object, the technical solution adopted in the utility model is: aorta dimensional culture single cell separator, it is characterized in that: comprise two slide glasss, one is common slide glass, its upper surface is with one deck mouse tail collagen, another is porose slide glass, its lower surface is with one deck organic silicon potting adhesive, by treated of two slide glasss with adhered by double sided plaster together, from the hole of porose slide glass, pour into the liquid matrigel of ice bath, make it filling between two slide glasss.After the one side of porose slide glass is processed with organic silicon potting adhesive, had hydrophobic characteristic, cell culture fluid can be stained with this face, so cell can not be attached to this length of looking unfamiliar; And after common slide glass processes with mouse tail collagen, cell take that it is grown for biological support attaches on it.The thickness that gap thickness between two slide glasss is double faced adhesive tape, can be controlled at 0.2-0.5mm, is a space that cell can be grown.
The utility model is the improvement to in-vitro culture model aortic annulus tissue culture, the growth of cell is limited in the space in the middle of two slide glasss, thereby has guaranteed the growth of a cell, is convenient to microscopic examination and takes pictures.
Compared with prior art, advantage is the utility model: this model is the improvement on aortic annulus model basis, has the advantage of aortic annulus model, as real simulation the situation of angiogenesis, operate relatively simply, easily observe; Can also carry out single celled research and separation and Culture, and unicellular being grown on slide glass looks more clear, easily observation.The utility model is mainly used in cultivating the individual cells of new vessel and to the unicellular separate study of carrying out.
