Increment of keratin-5 keratin-8-double positive cells induced by hypergravity is persistent.

<p>Immunostaining of thymic section from mice exposed to 2 <i>g</i> gravity (2G) for 14 days. Thymic frozen sections were immunostained with a combination of anti-keratin-8 antibodies (upper panels) and anti-keratin-5 (middle panels). Merged images are shown in lower panels. Mice were exposed to 2 <i>g</i> gravity (2G) for 3 days or left under 1G (Control). Vestibular apparatus are surgically disrupted in some groups of mice (VL). Data are representatives of 6 independent mice samples (N = 6). Scale bars indicate 100 μm. Data are representatives of 3 independent mice samples (N = 3).
