The invention discloses a drawing and loading device for cells, which relates to a cellular mechanics loading device that belongs to the medical instrument. The drawing and loading device for cells consists of a control part, a mechanical part and an electromagnetic part, which is characterized in that: the cells are cultivated on an elastic silicon membrane, and circumferential-direction drawing and compressive loading are carried out for the cells through a dynamic system, meanwhile, magnetic bead collagen with ferroferric oxide enveloped is attached to the surfaces of the cells through integrin family, then alternating magnetic field is respectively loaded at an upper and a lower bottoms of a cell cultivating box, rendering the cells to be drawn under the magnetic force while being under the circumferential stress in a base strain field, so as to control the transformation of the cells along the axis Z and control the cell morphology. By simulating the borne mechanical stress of cells under physiological conditions, the drawing and loading device for cells can realize mechanical loading with different dimensions under different mechanical forces, and has the advantages of simple structure, convenient use, wide application and excellent reproducibility, etc.
