LYN and chronic pancreatitis: These findings indicated that Lyn stimulated both chemotaxis and viability of stellate cells (this function of Lyn was previously established in other cellular systems; O'Laughlin-Brunner et al., 2001; Ptasznik et al., 2002) and Lyn-mediated chemotaxis and viability of stellate cells were increased in chronic pancreatitis, consistent with hyperactive Lyn kinase in chronic pancreatitis (Figure 1A).
