Description

A kind of human mesenchymal stem cell is at chondrocyte induction differential medium and preparation method
Technical field
The present invention relates to culture medium technical field, specially a kind of human mesenchymal stem cell is at chondrocyte induction differential medium And preparation method.
Background technology
Mescenchymal stem cell is present in the Various Tissues such as marrow, umbilical cord, fat, can be acquired by detaching, in vitro greatly Amount 1 research of amplification cultivation has shown that mescenchymal stem cell has good self-renewing and multidirectional point as a kind of multipotential stem cell Change potential, induced through specified conditions, can be broken up as multiple types groups such as fat thin, bone, cartilage, flesh, liver, nerve, skins Cell to be knitted, this characteristic is based on, mescenchymal stem cell has been attempted applied in Various Tissues and Multi-organ dysfunction repairing research, Wherein, the cartilaginous tissue for cartilage differentiation characteristic being oriented based on mescenchymal stem cell reproduces repairing research, in animal and clinic Satisfactory curative effect is obtained in the research of early period, has great clinical conversion potential, application market huge.
The special construction (no vascular distribution) of cartilaginous tissue, determines that it is difficult to the characteristic of self-regeneration after injury, Mesenchymal stem cells are induced as seed cell through specified conditions, can be thin by that will be done by mesenchyma to cartilage cell's directed differentiation The cartilaginous tissue that born of the same parents differentiate is transplanted, and clinical cartilage damage reparation and specific shaping operation demand can be met, and curative effect is aobvious It writes, but under existence conditions, human mesenchymal stem cell is at cartilage differentiation limited efficacy, it is therefore, dry to obtain enough mesenchymas The cartilage cell of cell origin carries out clinical application, need to lead to optimization Incubation Condition, be oriented induction, to short Sufficient and uniform cartilaginous tissue cell is efficiently obtained in phase and carries out injury repair, and existing human mesenchymal stem cell is at chondrocyte induction Differential medium ingredient is generally:DMEM culture mediums, 10% fetal calf serum (FBS), 1mM Sodium Pyruvates, 20ug/mL proline, 1XITS, 50 μ g/mL ascorbic acid, 100nM dexamethasone and 10ng/mL TGF-β.
The Chinese invention patent of 105695402 A of Publication No. CN discloses a kind of mescenchymal stem cell into chondrocyte induction Induce realignment and regrouping object and application method, the culture medium on DMEM in high glucose medium base, 10% fetal calf serum of addition, 50ug/mL L-AA -2-2 phosphates, 5ng/mL TGFb2,100nM dexamethasone, 25ug/mL vitamin Cs, 20ug/ ML proline, 2.5ug/mL Indomethacins, 1XITS+1premix, 1ug/ml chlormadinone esters, after 14-21 days Fiber differentiations It carries out cartilage cell and dyes identification, which just for umbilical cord derived mesenchymal stem cell at chondrocyte induction break up, lure It is undesirable to lead differentiation efficiency, specificity is relatively low, Osteoblast Differentiation sign occurs, and its contained chlormadinone ingredient is not easy to obtain, at This is higher, lacks actual application value.
In conclusion existing can not fill at chondrocyte induction differential medium between efficient stable induction people's Various Tissues source Matter stem cell breaks up to chondroblast, still needs to the differentiation condition more optimized and improves human mesenchymal stem cell into chondrocyte induction point Change efficiency, to provide advantageous item at the identification of cartilage differentiation ability and clinical cartilage damage treatment and beauty for mescenchymal stem cell Part.
Invention content
To solve existing in the prior art to ask at chondrocyte induction efficiency and specificity are not ideal enough, induction time is longer etc. Topic, the present invention provide it is a kind of can efficient stable induce a variety of people's tissue-derived mesenchymal stem cell directionals at the culture of cartilage differentiation Base and preparation method thereof.
A kind of human mesenchymal stem cell is at chondrocyte induction differential medium, it is characterised in that:There is following components to be made, α- MEM/HG-DMEM culture mediums, fetal calf serum 5-50% percents by volume, Sodium Pyruvate 50-200mg/ml concentration, ascorbic acid 20-200 μ g/ml concentration, proline 10-100 μ g/ml concentration, plug rice pine 50-500nM volumes, ITS0.5-20% volume basis Than, TGF-β 0.1-20ng/ml concentration, insulin-like growth factor -20.5-50nM volumes.
It is preferred that being made of following components, α-MEM/HG-DMEM culture mediums, fetal calf serum 5-50% percents by volume, acetone Sour sodium 50-200mg/ml concentration, ascorbic acid 20-100 μ g/ml concentration, proline 10-500 μ g/ml concentration, plug rice pine 50- 200nM volumes, ITS0.5-5% percents by volume, TGF-β 0.1-10ng/ml concentration, insulin-like growth factor -20.5-50nM Volume.
It is preferred that being made of following components, HG-DMEM culture mediums, 10% percent by volume of fetal calf serum, Sodium Pyruvate 100mg/ml concentration, 50 μ g/ml concentration of ascorbic acid, 20 μ g/ml concentration of proline, plug rice pine 100nM volumes, ITS1% volumes Percentage, TGF-β 5ng/ml concentration, insulin-like growth factor -220nM volumes.
Human mesenchymal stem cell provided by the invention is existing at the efficient inductive differentiation medium of cartilage and operational version At addition insulin-like growth factor -2 in cartilage differentiation culture medium.Dexamethasone in the existing differential medium at chondrocyte induction can The aggrecan of human mesenchymal stem cell is raised by activating WNT/ β-catenin signal paths;Ascorbic acid can pass through ERK signals are activated, to activate Runx2, Sox9 etc. to be transcribed at chondrocyte gene, promote Type Ⅱ collagen expression.TGF-β 3 can pass through Smad2/3/4 signals are activated, activation is transcribed at cartilage related gene, promotes mescenchymal stem cell at cartilage differentiation 6.Proline can It is maintained by forming the α collagen helix stable structure that proline ring promotes mescenchymal stem cell induction to generate.Containing insulin, turn The ITS of ferritin and selenium equally can be by raising Sox9 gene transcript expressions, to promote the expression of Type Ⅱ collagen.The present invention Insulin-like growth factor -2 is added in the existing differential medium ingredient at chondrocyte induction.We have found under study for action, insulin Growth factor-2 can be dialled further up the mRNA transcriptions of Sox9 and BMP2 in mescenchymal stem cell, promote Type Ⅱ collagen expression heavy Product, positive regulation aggrecan, cartilage oligo-substrate protein and mucopolysaccharide expression, to further efficiently the human world be promoted to fill Matter stem cell is to cartilage cell's specific differentiation.
A kind of human mesenchymal stem cell includes the following steps at the preparation method of chondrocyte induction differential medium,
(1), culture dish sterilizes, and is rinsed well with clear water after culture dish is scrubbed with suds, and paper or cloth bag are used after drying It is good, or in metal box, be placed in high-pressure steam sterilizing pan and sterilize, sterilising temp should be 121 DEG C, and sterilization time should be 3min is dried for standby after sterilizing;
