Description
Technical field
The utility model relates to a kind of stem cell in vitro enrichment isolation systems in stem-cell therapy field.
Background technique
The autologous stem cells beneficiation technologies of Recent study discovery, i.e., without the stem cell of in vitro culture, direct Hui Zhi,
Not only it is avoided that immunological rejection, and the autologous stem cells being enriched with can use local microenvironment and realize its directional induction
Thus box regeneration brings hope to the treatment of some diseases.Its biggest advantage is that being not necessarily in vitro culture, can perform the operation
The technical issues of same period carries out, and avoids complex operations and relevant ethnics Problem, this is that conventional method can not substitute and compare
Quasi-.With deepening continuously for stem-cell research, with stem cell (bone marrow stem cells, BMSCs) conduct
The cell therapy of seed cell receives more and more attention.BMSCs promotes the zoopery of Bone Defect Repari more to be affirmed
Effect, but carry out clinical treatment be still subject to many limitations.First, when being treated with autogenous bone marrow blood merely, because of unit bodies
BMSCs amount reduces curative effect less in product marrow blood.Second, it is expanded according to cell injuring model, then patient will wait one section
Time just can be carried out back plant operation, generally about need for 3 weeks, the needs for not being able to satisfy clinical emergency or treating in time；And body
Outer culture must avoid the pollution of various microorganisms, to the more demanding of environment and equipment, therefore increase medical expense；In addition
For in vitro culture often using Cow placeta serum as culture medium, this also brings the ethics dispute of clinical cytology treatment；Without training in vitro
The feeding BMSCs stem cell enrichment screening technique that high concentration can be obtained in art is developed.
Cell enrichment screening technique mainly has at present: flow cytometric sorting method, magnetic activated cell seperation, adherent screening method
And density-gradient centrifugation method.Flow cytometric sorting method is the antigen marker knot using special fluorescence antibody and cell surface
It closes, then stem cell is sorted using flow cytometer.Although it separates cell rapidly, purity is high, somewhat expensive,
The trace cell too low to content is difficult to separate, and cannot handle a large amount of cell sample, to obtain sterile stem cell suspension
It is highly difficult.
Magnetic activated cell seperation is using micro- magnetic bead not only in combination with protein, but also the characteristics of can be attracted by magnet, by antibody
It is coated on magnetic bead, by forming antigen-antibody magnetic bead immune complex in conjunction with stem cell surface specific antigen.When this
It when compound passes through splitter, under magneticaction, i.e., separates with mother liquor, so that stem cell be made to separate with other substances, reaches
The purpose of screening.It is larger to the activity influence of cell, and the rate of recovery only has 60%-75%, may result in cell complete deactivation,
Equally operate it is more complex, it is expensive.
Adherent screening method is the most common bone marrow stroma stem cell screening technique in current laboratory, by training marrow blood
It supports and is cultivated in ware, bone marrow stroma stem cell is adherent after 24-48h, whereby can be by bone marrow stroma stem cell and other not adherent bones
Myelocyte separation.It needs the time longer, is related to the in vitro culture of cell, and clinical use acquires a certain degree of difficulty.
Density-gradient centrifugation method is the method for common concentration and separation cell, utilizes the difference of different cell component density gradients
It is different, cell can be made in different levels concentration by centrifugation, the separating liquid of different specific weight be used in combination, by the cell of different specific weight
Carry out multi_layer extraction.It needs finally to need to wash away separating medium again using separating medium, to keep the sterile need of whole operation
Want special equipment, somewhat expensive.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of stem cell in vitro enrichment isolation system
System, can directly obtain stem cell suspension, more be able to satisfy clinical a variety of needs, due to ceramic without using biological stephanoporate,
The efficiency of stem cell enrichment screening can be effectively improved, stem cell enrichment screening is reduced, obtains cost and the time of stem cell suspension,
Meet the requirement of emergency treatment clinical operation.
