Intervertebral Disc Stability in Organ Culture: Rat versus Rabbit
ثبت نشده
چکیده
INTRODUCTION: In vitro organ culture studies of the intervertebral disc (IVD) have been commonly used to understand the biologic and mechanical pathways contributing to disc degeneration. In particular, small animal models such as rat and rabbit have many advantages over large animals in an organ culture standpoint. Temporal and spatial stability of cell viability and extracellular matrix content are deemed essential prerequisites in order to deduce meaning inferences on IVD biology. Culture conditions aside, previous data from our lab and others [1] indicate that IVD culture stability could also be species-dependent. The purpose of this study was to evaluate the stability of rat and rabbit IVDs in vitro and to compare morphologic differences between the two species when cultured at identical culture conditions.

Effect of Static Load on the Nucleus Pulposus of Rabbit Intervertebral Disc Motion Segment in an Organ Culture
The development of mechanically active culture systems helps in understanding of the role of mechanical stress in intervertebral disc (IVD) degeneration. Motion segment cultures facilitate the application and control of mechanical loads. The purpose of this study was to establish a culturing method for rabbit IVD motion segments to observe the effect of static load on the whole disc organ. Segm...

Effects of Morphine Dependency on Intervertebral Disc in the Rat
Background: A large proportion of patients presenting with lumbar disc disease are opium addicts in our region. It was, therefore, hypothesized that morphine might affect the intervertebral disc. We investigated the histological findings of morphine dependency on intervertebral discs in rat. Methods: Forty NMRI adult male rats (230-250 g) placed on ordinary diet and received aqueous solution of...

INTRODUCTION Despite many advances in our understanding of the molecular basis of disc degeneration, there remains a paucity of preclinical models which can be used to study the biochemical and molecular events that drive disc degeneration, and the effects of potential therapeutic interventions. The goal of this study is to characterize global gene expression changes in a disc organ culture sys...
