TTK expression and H2Bub1 levels were decreased in BM-MSCs in senile osteoporosis
(A and B) Western blot analysis of the levels of TTK and H2Bub1 in BM-MSCs from 2-month-old and 20-month-old mice, patients with traffic injuries and patients with senile osteoporosis. (C and D) Immunofluorescence staining (scale bar, 100 μm) showed Ttk expression and H2Bub1 levels in the Ocn+ osteoblast lineage in 2-month-old and 20-month-old mice (white arrows). (E and F) Immunofluorescence staining (scale bar, 100 μm) showed TTK expression and H2Bub1 levels in the OCN+ osteoblast lineage in young patients with traffic injuries and patients with senile osteoporosis (white arrows). All data are presented as mean ± SD; n = 3; ∗p < 0.05.
