“…The etiology of IDD is multifactorial and not completely elucidated. To date, multiple factors have been recognized involved in the progression of IDD, such as ageing, smoking, diabetes mellitus (DM), obesity, abnormal mechanical load and genetic predisposition ( Figure 1 ) ( Kim et al, 2009 ; Le Maitre et al, 2007 ; Jeong et al, 2014 ; Desmoulin et al, 2020 ; Maclean et al, 2004 ; Walsh and Lotz, 2004 ; Wuertz et al, 2009 ; Kalb et al, 2012 ; Martirosyan et al, 2016 ; Alpantaki et al, 2019 ; Kakadiya et al, 2020 ; Livshits et al, 2001 ; Chen et al, 2018 ; Cannata et al, 2020 ). In response to those risk factors, various crucial pathological processes develop, including the loss of resident IVD cells, ECM remodeling, inflammation and oxidative stress ( Figure 1 ) ( Gruber and Hanley, 1998 ; Nasto et al, 2013 ; Suzuki et al, 2015 ; Lyu et al, 2021 ).…”
