Bone quality relies on hyaluronan synthesis - Insights from mice with complete knockout of hyaluronan synthase expression.

ABSTRACT: Bone consists of a complex mineralised matrix that is maintained by a controlled equilibrium of synthesis and resorption by different cell types. Hyaluronan (HA) is an important glycosaminoglycan in many tissues including bone. Previously, the importance of HA synthesis for bone development during embryogenesis has been shown. We therefore investigated whether HA synthesis is involved in adult bone turnover and whether abrogation of HA synthesis in adult mice would alter bone quality. To achieve complete abrogation of HA synthesis in adult mice, we generated a novel Has-total knockout (Has-tKO) mouse model in which a constitutive knockout of Has1 and Has3 was combined with an inducible, Ubc-Cre-driven Has2 knockout. By comparing bone tissue from wild-type, Has1,3 double knockout and Has-tK
