23 Jul Device for cell microsphere filamentation preparation based on type I collagen gel
Abstract
The invention relates to a device for cell microsphere filamentation preparation based on type I collagen gel. In the traditional method, the large-scale amplification of cells is carried out through passage, manually harvested seed cells are also compounded with biomaterials through manual inoculation, the operation is simple and complicated, the pollution is easy to cause, and the cell inoculation is not uniform. The device comprises a cell microsphere filamentation device, a control unit and a measuring unit, wherein the cell microsphere filamentation device consists of three parts: a cellmicrosphere and type I collagen gel mixing positioning mechanism, a cell microsphere silk thread shaping mechanism and a cell microsphere silk thread collecting mechanism. The device has the advantages that cell microsphere active silk threads covered by type I collagen can be prepared, the defect that cell suspension can not control the cell position state in the cell inoculation and the cell treatment is overcome, a large number of different kinds of cell microsphere single silks are provided for the precise construction of complicated tissues and organs, and the device is provided for tissue engineering and the clinical application of regenerative medicine.
