Description

Serum free medium
Technical field
The present invention relates to stem cell and bioengineering field, specifically a kind of serum-free training for being mainly used in stem cell culture Support base.
Background technology
Mescenchymal stem cell (mesenchymal stem cells, MSC) is a kind of adult with multi-lineage potential Stem cell, the Various Tissues organ from human body include umbilical cord, placenta, marrow, dental pulp, peripheral blood, Cord blood and corneal limbus Deng.Increasing research shows that MSC can repair impaired histoorgan, has therapeutic action to many diseases.MSC can The disease treated and obtain certain curative effect includes myocardial infarction, neurogenic disease, spinal injury, hepatic sclerosis, lupus erythematosus etc., MSC can promote wound healing, also with hematopoiesis support and immunoregulatory function.Because MSC has treatment to a variety of diseases Effect, MSC are paid close attention to by researcher extensively, and the research to MSC is also always the big focus in cell field.With right MSC researchs are goed deep into, and MSC cure mechanism is also gradually revealed.Found at present by studying, MSC treats the main machine of disease Make unlike people be initially considered that by being divided into and replacing impaired histocyte, but it is adjusted by paracrine mechanism The activity of its cell and function, so as to repair impaired cell.As MSC can secrete IGF-1 (IGF, Insulin-like growth factor 1) and Annexin-A1 strengthen the function of islet tissue.It is thin that MSC can secrete liver The intracellular growth factor (Hepatocyte growth factor, HGF) promotes the reparation of angiogenesis and injury tissue.In addition, Because some MSC immunogenicity is very low, obvious rejection can't occur after transplanting, this also causes facing for MSC Bed application is increasingly favored by people, such as the MSC in umbilical cord source.
Being separately cultured for MSC is an important prerequisite condition to its scientific research and clinical practice, MSC cell quality It is two key factors before its application with security.Current many mechanisms mainly use hyclone (Fetal to MSC cultures Bovine Serum, FBS).Serum is to eliminate fibrinous blood plasma, and its composition is sufficiently complex.Why serum can be protected Cell and promote cell growth be because serum in containing many cells need nutritional ingredient, the life of cell can be maintained for a long time Long and statocyte physiological function.Main Ingredients and Appearance in serum includes 1) growth factor, such as PDGF, FGF, IGF-1, EGF etc., These growth factors can promote propagation and the division of cell.2) adherent material is promoted, can such as fibronectin and hydrocortisone Promote cell attachment and stretching, extension.3) protein matter, such as albumin, transferrins, globulin and protease inhibitors, these Albumen can transport the nutriments such as vitamin, lipid, promote cell metabolism and protect cell not hindered by protease Evil.4) other compositions also include trace element, lipid, hormone, vitamin, carbohydrate, amino acid, nucleic acid, anti-oxidant Material and buffer composition etc..
Because serum has abundant nutritional ingredient and significant cell culture effect, people use always in recent decades Major Nutrient material of the serum as cell growth.Nevertheless, serum still has some problems during use.By It is different in the source of serum, i.e., constantly gathered out of different animal body, individual difference can cause battalion contained in serum Form point and the difference of ratio.So even the serum of same brand can also have the difference between batch, and sometimes this Species diversity is more apparent, can so cause the result difference of cell culture larger, it is difficult to control stability and the repetition of cell culture Property.Although most of composition at present in serum, it is known that but still some is unclear, wherein it is useless to include some Metabolite and some be unfavorable for the harmful substance of cell growth, the growing multiplication of cell can be influenceed to a certain extent.Remove Outside this, because serum origin is in animal body, the pathogenic originals such as microorganism and virus may be contained.Animal protein in serum Belong to heterologous protein, carrying out treatment using the cell of serum free culture system is likely to result in immunological rejection.Due to serum exist it is upper Some problems are stated, clinical treatment is not particularly suited for the cell of its culture.In order to better meet cell clinical practice and science The needs of research, the clear and definite serum free medium of constituent are safer and preferable selections.Developing serum free medium needs Will using it is known and to cell it is harmless can maintain the various compounds of cell growth to prepare.
