Abstract
The hypoxic nucleus pulposus cells were thought to contain few, functionally redundant mitochondria. However in contrast to this widely held notion, new evidence shows presence of functional mitochondrial networks in disc cells. The lecture will discuss this evidence and provide insights into how microenvironmental cues govern mitochondrial function. The lecture will also discuss emerging evidence on how mitochondrial dysfunction of nucleus pulposus cells results in metabolic dysregulation and acquisition of a state that promotes inflammation and degeneration.
