Abstract
A method for in-vitro fusion of stem cells and a porous biomaterial includes the steps: firstly, enabling the porous biomaterial (2) to be hermetic by the aid of a hermetic material (1), and enabling one end (3a) of each of two pipelines (3) to be hermetic in the porous biomaterial (2) in the hermetic process; secondly, connecting an input device (4) with the other end (3b) of one pipeline (3); thirdly, connecting a negative pressure device (5) with the other end (3b) of the other pipeline (3); and fourthly, utilizing the input device (4) to push in stem cell suspension while enabling one end of the porous biomaterial to be in the negative pressure state by the aid of the negative pressure device (5), so that the stem cell suspension completely reaches the inside of the porous biomaterial for fusion. The hermetic material (1) is soft silica gel or a sticky plastic film. The method has the advantages of capability of effectively realizing fusion of crisp porous biomaterials in various shapes and stem cells, quickness, high efficiency, simplicity in processing and capability of being widely applied to scientific research and clinical application.
Description
Technical field
The present invention relates to stem cell experiment and Application Areas, the specifically external fusing device of a kind of stem cell and porous biomaterial.
Background technology
For the fixing high biomaterial of proterties and fragility, prior art mainly drops in stem cell suspension each surface of material and reaches the compound of stem cell and material; For the closed unit of granular porous material application solid shape by stem cell suspension by material by cell and Material cladding.
Prior art mainly contains following shortcoming: 1. cell suspension is splashed into material surface, due to after surface void sealed by cell, material inside can not reach effective cell concentration, when especially material is larger; By cell suspension when being placed in the material of closed unit of solid shape, because the gap of material and closed unit wall easily makes suspension pass through gap but not through material, and this device is not suitable for non-particulate shape and the large material of fragility.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and stem cell effectively can be compound to the surface of porous biomaterial and inner method for in-vitro fusion.
In order to address the above problem technical scheme of the present invention, be such:
Stem cell and a porous biomaterial method for in-vitro fusion, is characterized in that, the steps include:
1. with enclosed material, porous biomaterial is airtight, in airtight process, one end of two pipelines is enclosed in porous biomaterial;
2. input unit is connected with the other end of a pipeline;
3. negative pressure device is connected with the other end of another root pipeline;
4. use input unit to push stem cell suspension, use negative pressure device to make porous biomaterial in one end negative pressure state simultaneously, make stem cell suspension arrive material internal completely and merge;
Described enclosed material is soft silica gel or viscous plastic film.
Described input unit is ordinary syringe.
Described negative pressure device is ordinary syringe or vacuum pump.
Positively effect of the present invention is: apply specific closed material and guarantee the effectively difform biological stephanoporate material of sealing, at one end in the situation of negative pressure, stem cell suspension is pushed, thereby guarantee that suspension can be effectively inner through biomaterial, can effectively solve biological stephanoporate material that different shape, quality are crisp and the problem of stem cell fusion, method is quick, efficiently, simple to operate, can be widely used in scientific research and clinical application.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, describe the present invention in detail:
Fig. 1 is the stereographic map of embodiment 1.
Number in the figure is: 1-enclosed material, 2-porous biomaterial, 3-pipeline, 4-input unit, 5-negative pressure device.
Embodiment
For technique means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
embodiment 1
Stem cell and a porous biomaterial method for in-vitro fusion, step is:
1. use enclosed material 1 that porous biomaterial 2 is airtight, in airtight process, one end 3a of two pipelines 3 is enclosed in porous biomaterial 2, described sealing material 1 is soft silica gel or viscous plastic film;
2. input unit 4 is connected with the other end 3b of pipeline 3, as shown in Figure 1, described input unit 4 is ordinary syringe, before connecting, in syringe, should pack stem cell suspension in advance;
3. negative pressure device 5 is connected with the other end 3b of pipeline 3, as shown in Figure 1, described negative pressure device 5 is ordinary syringe, before being connected with pipeline 3 syringe planted agent in vacuum state, with one end of guaranteeing porous material in negative pressure state;
4. apply input unit 4 and push stem cell suspension, pull the piston of negative pressure device 5 simultaneously, make one end of porous biomaterial always in negative pressure state, make stem cell suspension arrive material internal completely and merge.
embodiment 2
When porous biomaterial volume is larger, when syringe cannot meet required stem cell suspension amount, negative pressure device 5 can adopt vacuum pump.
Positively effect of the present invention is: apply specific closed material and guarantee the effectively difform biological stephanoporate material of sealing, at one end in the situation of negative pressure, stem cell suspension is pushed, thereby guarantee that suspension can be effectively inner through biomaterial, can effectively solve biological stephanoporate material that different shape, quality are crisp and the problem of stem cell fusion, method is quick, efficiently, simple to operate, can be widely used in scientific research and clinical application.
