FGF18 and osteoarthritis: This includes development of FGF21 based therapeutics for metabolic syndrome (Kharitonenkov & Shanafelt, 2008; Kharitonenkov & Shanafelt, 2009; Zhang & Li, 2014), of FGF7 for oral mucositis (Goldberg et al., 2013) and of FGF18 in osteoarthritis (Carli et al., 2012; Mori et al., 2014), it is likely that we will see FGF biologics in clinical use in the West, as well as in the East.
