Fig. 4. High KCl Induced Secretion is Decreased with Age in in Lacrimal Glands in TSP-1−/− Compared to WT Mice.
Lacrimal gland pieces were stimulated with normal 4 mM KCl (basal) and high 75 mM KCl and protein secretion was measured in 4 (a), 12 (b), and 24 (c) week old mice. Data are mean ± SEM from at least three independent animals for each condition. * indicates statistically significant different from basal; #indicates a significant difference from WT.
