the effect of low-intensity pulsed ultrasound stimulation on neonate mouse spermatogonial stem cells
objective: this study presents an efficient, cost-effective method to improve proliferation and colonization of spermatogonial stem cells (sscs) in vitro. methods: isolated sscs from neonate mice were cultured in dmem culture medium with 10% fetal bovine serum (fbs). in the first phase of the study, the temperature was controlled by low intensity pulsed ultrasound stimulation (lipus) of the pla...
متن کاملLow Intensity Pulsed Ultrasound Promotes the Extracellular Matrix Synthesis of Degenerative Human Nucleus Pulposus Cells Through FAK/PI3K/Akt Pathway.
STUDY DESIGN In vitro experimental study. OBJECTIVE To investigate the effect of low-intensity pulsed ultrasound (LIPUS) on the extracellular matrix (ECM) synthesis of degenerative human nucleus pulposus cells and explore the molecular mechanism. SUMMARY OF BACKGROUND DATA LIPUS has been used successfully for bone fracture healing and been proved to be effective in stimulating ECM metabolis...

INTRODUCTION Ultrasound has proven to be an important therapeutic resource regarding musculoskeletal disease and is routinely used in physical therapy and medicine both therapeutically and diagnostically. The aim of the present study was to analyse the effects with different ultrasound intensities in order to establish the ideal radiation level in cell cultures. MATERIAL AND METHODS FIBROBLAS...
متن کاملEffect of low intensity pulsed ultrasound stimulation on sinus augmentation in rabbits
OBJECTIVES The objective of the present study was to evaluate the efficacy of low intensity pulsed ultrasound stimulation (LIPUS) and to determine the optimal frequency for enhancing bone regeneration in sinus augmentation using a rabbit model. MATERIAL AND METHODS Thirty male rabbits underwent sinus augmentation. Two rectangular nasal bone windows were outlined bilaterally. LIPUS was applied...
متن کاملLow-intensity pulsed ultrasound stimulates cell proliferation, proteoglycan synthesis and expression of growth factor-related genes in human nucleus pulposus cell line.
Low-intensity pulsed ultrasound (LIPUS) stimulation has been shown to effect differentiation and activation of human chondrocytes. A study involving stimulation of rabbit disc cells with LIPUS revealed upregulation of cell proliferation and proteoglycan (PG) synthesis. However, the effect of LIPUS on human nucleus pulposus cells has not been investigated. In the present study, therefore, we inv...
