Description
Technical field:
the invention relates to the technical field of biological sample extraction, in particular to an automatic umbilical cord hua tong gum dicer.
The background technology is as follows:
modern cell biology research shows that stem cells with self-renewal and multipotency can be applied to the treatment and rehabilitation of various diseases. However, with the development of intensive research and clinical application, stem cells are found to have problems, for example, ethical, legal, immune rejection, tumorigenicity and the like in the application of embryonic stem cells; the autologous bone marrow mononuclear cells have the problems of complex components, low stem cell content with multidirectional differentiation potential, limited differentiation potential and the like; autologous bone marrow MSCs are limited in source, cell proliferation and differentiation potential is obviously reduced along with the increase of age, and in-vitro long-term expansion reduces in-vivo differentiation homing potential. The existing extraction means of autologous bone marrow often brings great physiological pain to patients, and the problems seriously restrict the research of stem cells, especially mesenchymal stem cells in clinical application.
In response to the above problems, in recent years, with the increasing reports of related studies, researchers have shifted the field of view of Mesenchymal Stem Cell (MSC) sources to umbilical cord blood, umbilical cord and placenta. They have the particular advantage: the source is sufficient, the probability of virus pollution is low, the immunogenicity is weak, the cells are more original, the disputes in ethical law are avoided, and the operation is simple and convenient. Obtaining umbilical cord mesenchymal stem cells is a very efficient method. Today, there are two methods for obtaining umbilical cord mesenchymal stem cells: 1. tissue block adherence method; 2. enzymatic digestion
The tissue block adhering process includes the steps of obtaining neonate umbilical cord, washing away residual umbilical cord blood with isotonic buffer salt solution or physiological saline solution, eliminating umbilical artery, umbilical vein and the outer amniotic membrane of umbilical cord in a sterile and clean biosafety cabinet, extracting to obtain Huatong glue, cutting the Huatong glue into small blocks, and subsequent inoculation onto the bottom plate of culture dish for culture to obtain cell.
The enzyme digestion method is to digest the Huatong glue by the active enzyme of single component or composite component and obtain the cell from the digestion liquid.
The two methods have advantages and disadvantages:
1. tissue block adherence method: the method has the advantages of simple operation, low cost, relatively fixed operation standard and relatively uniform cells obtained by culture. The disadvantage is the long primary culture time (7-10 days visible primary cell climbing out).
2. Enzymatic digestion: the advantage is that the procedure is rapid and the primary culture time is very short (a large number of primary cells are visible for 3 d). The disadvantages are that the cost is high, the cells obtained by culture are not uniform, the enzyme use method in the digestion process is not uniform, and the enzyme liquid can damage the cells when the digestion time is too long.
Therefore, the method for obtaining umbilical cord Mesenchymal Stem Cells (MSC) is widely used at present, and is mostly carried out by a tissue mass adherence method.
At present, the umbilical cord Huatong glue is manually cut to obtain umbilical cord Huatong glue cut blocks for storage, but the umbilical cord Huatong glue is limited by the high toughness and the smooth surface of the Huatong glue and the narrow space for operation, the efficiency of cutting the umbilical cord Huatong glue is extremely low, and the difficulty of obtaining MSC by a tissue block adherence method is great occupied manpower and time.
