Abstract: Periodontal ligament stem cells (PDLSCs) have great potential in the treatment of periodontal diseases and other tissue regeneration fields, and the study of their biological behavior is helpful to the development of regenerative medicine. Mechanical stimuli such as mechanical stress, matrix surface morphology, and elasticity not only affect the proliferation and migration of PDLSCs, but also have the potential to induce the differentiation of PDLSCs into bone, tendon, myocardium, cornea, and other somatic cells, and this process is regulated by the time dimension. In addition, the perception of PDLSCs to mechanical stimuli also has memory. PDLSCs can retain the mechanical information in the past culture environment and affect the direction of their future differentiation. Current studies have confirmed that mechanical stimulation signals of PDLSCs can be transmitted into cells through integrins and ion channels to regulate cell behavior. In this paper, the effects of mechanical stimulation on the biological behavior of PDLSCs are reviewed, in order to provide new ideas for the regulation of PDLSCs differentiation in tissue engineering.
