The expression of chromatin protein HMGB2 is restricted towards the SZ, which consists of cells expressing mesenchymal stem cell markers. Aging associated loss of HMGB2 and gene deletion are related to decreased SZ cellularity VEGFR inhibition and early onset OA. This study addressed HMGB2 expression patterns in MSC and its role for the duration of differentiation. HMGB2 was detected at greater ranges in human MSC as in comparison to human articular chondrocytes and its expression declined through chondrogenic differentiation of MSC. Lentiviral HMGB2 transduction of MSC suppressed chondrogenesis as reflected by an inhibition of Col2a1 and Col10a1 expression. Conversely, in bone marrow MSC from Hmgb2 / mice, Col10a1 was much more strongly expressed than in wildtype MSC.

This is often steady with in vivo final results from mouse growth plates displaying that Hmgb2 is expressed CB1 receptor signaling in proliferating and prehypertrophic zones but not in hypertrophic cartilage exactly where Col10a1 is strongly expressed. Osteogenesis was also accelerated in Hmgb2 / MSC. The expression of Runx2, which plays a major part in late stage chondrocyte differentiation, was improved in Hmgb2 / MSC and HMGB2 negatively regulated the stimulatory impact of Wnt/b catenin signaling about the Runx2 proximal promoter. These results demonstrate that HMGB2 expression is inversely correlated together with the differentiation standing of MSC and that HMGB2 suppresses chondrogenic differentiation. The aging related reduction of HMGB2 in articular cartilage may perhaps represent a mechanism accountable for the decline in adult cartilage stem cell populations.
