T3 is essential for normal skeletal development. Childhood hypothyroidism causes delayed bone formation, whereas T3-excess accelerates growth and epiphyseal closure. Fibroblast growth factors (FGFs) act via receptor tyrosine kinases (FGFRs) to inhibit chondrocyte proliferation, matrix production and skeletal maturation. Dimerisation of FGFRs and their functional interaction with FGFs requires heparan sulphate proteoglycans (HSPGs). We recently showed that T3 induces FGFR-1 exp...
