OBJECTIVE: To examine if triiodothyronine (T3) increases osteogenic differentiation adipose tissue derived stem cells (ASCs) from ovariectomized adult rats with osteoporosis compared with young rats and adult rats without osteoporosis. MATERIALS AND METHODS: The ASCs were cultured in osteogenic medium and distributed into seven groups: 1) ASCs of young rats without osteoporosis; 2) ASCs of adult rats without osteoporosis; 3) ASCs of adult rats with osteoporosis and 4, 5, 6 and 7) ASCs of adult rats with osteoporosis treated with […]

OBJECTIVE: To examine if triiodothyronine (T3) increases osteogenic differentiation in bone marrow mesenchymal stem cells (BMMSCs) of adult rats compared with young rats. MATERIALS AND METHODS: BMMSCs were cultured in osteogenic medium and distributed into six groups: 1) BMMSCs of young rats; 2) BMMSCs of adult rats; 3, 4, 5 and 6) BMMSCs of adult rats with T3 (0.01, 1, 100 to 1000 nM). We analyzed alkaline phosphatase activity, dimethylthiazol (MTT) conversion, and collagen synthesis at 7, 14, and 21 […]
