Device for separating and purifying placenta totipotent stem cells

Abstract

The invention discloses a device for separating and purifying placenta totipotent stem cells. The device comprises an upper sealing cover, a temperature and humidity controller, a door, a box, a vibrating centrifugal tube, a bottom sealing plate, a purifying beaker, a fixed slide rail, a fixed base, a limiting fixed block, a data connecting socket, a filter screen and a connecting hinge. The device has the beneficial effects: the temperature and humidity controller is capable of guaranteeing suitability of inner separating and purifying environment and guaranteeing activity of placenta totipotent stem cells; the vibrating centrifugal tube is capable of preventing solution splashing and leakage caused by centrifugation and guaranteeing smooth proceeding of centrifugation; the vibrating centrifugal tube can be conveniently mounted and dismounted; the purifying beaker is convenient for separation and purification operations which can be finished in one device; the purifying beaker can beconveniently taken out and fixed and is capable of preventing the purifying solution from splashing and leakage; the fixed slide rail is capable of guaranteeing smoothness and stability of operation and is convenient for purification operation; constitutional units of the filter screen are in same size and shape and are fixed above the bottom sealing plate in the manner of slots; working efficiency is increased; operation steps are simplified; mounting, dismounting and replacement are convenient.

Description

technical field [0001] The invention relates to a separation and purification device, in particular to a placental totipotent stem cell separation and purification device, which belongs to the technical field of biological cell separation and purification. Background technique [0002] A cell dies, and at the same time, a considerable number of new cells are produced to form metabolism. These new cells come from stem cells. Stem cells are a group of cells with self-replication and multi-directional differentiation potential. They can continuously renew themselves and transform under specific conditions. Differentiate into one or more cells or tissues with specific functions. In recent years, with the deepening of research, it has been possible to extract and cultivate various stem cells in tissues such as umbilical cord blood, umbilical cord, and placenta. Among them, the placenta has a "treasure of stem cells" It is said that the number of stem cells in the placenta is equi...

Problems solved by technology

[0003] At present, there are still some problems in the placental totipotent stem cell separation and purification device. First, the existing placental totipotent stem cell separation and purification device is generally divided into steps for separation and purification, which is more troublesome and some interfering problems will occur during the period. 1. The existing placenta totipotent stem cell separation and purification device does not have much control over the internal environment, which will have a certain impact on cell activity. Third, the existing placenta totipotent stem cell separation and purification device often needs to be filtered after separation. Remove internal impurities, the steps are more cumbersome
