Abstract Mechanical stimulation of plants can be caused by various abiotic and biotic environmental factors. Apart from the negative consequences, it can also cause positive changes, such as acclimatization of plants to stress conditions. Therefore, it is necessary to study the physiological and biochemical mechanisms underlying the response of plants to mechanical stimulation. Our aim was to evaluate the response of model plant Arabidopsis thaliana to a moderate force of 5 N (newton) for 20 s, which could be compared with the pressure caused by animal movement and weather conditions such as heavy rain. Mechanically stimulated leaves were sampled 1 h… More >

Abstract Mesenchymal Stem Cells (MSCs) are recruited to the musculoskeletal system following trauma [1] or chemicals stimulation [2]. The regulation of their differentiation into either bone or cartilage cells is a key question. The fluid shear stress (FSS) is of pivotal importance to the development, function and even the repair of all tissues in the musculoskeletal system [3]. We previously found that MSCs are sensitive enough to distinguish a slight change of FSS stimulation during their differentiation commitment to bone or cartilage cells, and the internal mechanisms. In detail, MSCs were exposed to laminar FSS linearly increased from 0 to 10… More >

Abstract Zonula occludens-1 (ZO-1) is a peripheral membrane protein belongs to the family of zona occludens proteins and plays an important role as a scaffold protein which cross-links and anchors tight junction (TJ) strand proteins, within the lipid bilayer, to the actin cytoskeleton^[1-2]. Stent implantation is the most effective method in the treatment of cardiovascular disease which always destroy junctions of endothelial cells, the functions of the tight junction were also affected. However, the role of ZO-1 before and after stent implantation has not been fully understood. In this study, the expression of ZO-1 were analyzed by qPCR, western blot and… More >

Abstract Tight junctions are the most apical intercellular junctions of the lateral membrane in endothelial cells, regulating the paracellular material and energy exchange and maintain plasma membrane polarity. Occludin protein is one of the important proteins involved in endothelial tight junctions, and also closely related to the occurrence of atherosclerosis. Therefore, the study of occludin is valuable ^[1]. With the implantation of coronary stents, the integrity of the vascular endothelium is damaged and the local mechanical environment at the stent segment was changed ^[2]. The present study tried to explore the impact of mechanical stimulation after stent implantation on the expression… More >

Abstract Stent implantation is the most effective method in the treatment of cardiovascular disease which always destroy the integrity of the vascular endothelium and the local mechanical environment at the stent segment was changed, especially the biodegradable stents [1]. In this study, 3D printed biodegradable poly (L-lactic acid) stents were implanted into SD rat abdominal aorta and the endothelialization, intimal hyperplasia, and MGF after stent implantation were studied. Besides, based on the MGF we explored the effects of mechanical stimulation on MGF express in vascular endothelial cells and smooth muscle cells, and also the effects of MGF with different concentrations on… More >

Abstract It has been widely accepted that movement of human body causes the fluid flow through pores or channels inside bone and subsequently on osteoblasts on the surface of trabeculae and osteocytes inside lacunae. The mechanism of calcium response in a bone cell and calcium transfer between bone cells is critical in understanding the communication between bone cells and calcium deposition on bone matrix. Our previous works have demonstrated that when micropatterned osteoblastic cell network with gap junctions was exposed to fluid flow, extracellular ATP diffusion following the activation of calcium response in neighboring cells plays more important roles in calcium… More >

Abstract Background: Environmental factors affect stem cell differentiation. In addition to chemical factors, mechanical signals have been suggested to enhance myogenic differentiation of stem cells. Therefore, this study was undertaken to illustrate and compare the effect of chemical and mechanical stimuli on Myogenin (MyoG) and Myosin heavy chani 2 (Myh2) expression of mouse bone marrowderived mesenchymal stem cells (BMSCs) and embryonic stem cells (ESCs). Methods: After isolation and expansion of BMSCs and generation of embryoid bodies and spontaneous differentiation of ESCs, cells were examined in 4 groups: (1) control group: untreated cells; (2) chemical group: cells incubated in myogenic medium (5-azacythidine… More >
