Abslrad-This paper investigates cell growth behavior under a shear stress environment. SJRC rabbit cornea cells were grown on a silicon rubber membrane fabricated by micro molding technology. The membrane was clamped inside a stress apparatus, and air pressure was employed to apply shear stress on the silicone rubber membrane for cell growth testing. Different air pressures, from 0.4, 0.7, 1.0 to 1.8 Psig (2.76~10'-1.24~10' Pa, gauge pressure), were applied on the membrane to generate steady shear strain on ceU for more than 18 hours, respectively. The results showed the decrease of cell multiplication for the increase of air pressure on the membrane. A large decrease of cell multiplication at around 0.7 Psig suggested the turning point of cell growth bebanor, and this point was also observed from the morphology change of the cell at the similar pressure level. This result will be beneficial for the growth control of corneal tissue.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
