title: [Effect of allogenic adipose-derived stem cell transplantation on bone mass in rats with glucocorticoid-induced osteoporosis].
abstract: OBJECTIVE
  To investigate the effects of systemic transplantation of allogenic adipose-derived stem cells (ADSCs), the main undifferentiated cells in the supporting-storing system based on the fasciology hypothesis, on the bone mineral density (BMD) and histomorphometry in rats with glucocorticoid-induced osteoporosis (GIOP) rats, and explore a new therapeutic approach for osteoporosis.
  
  
  METHODS
  Forty female adult Wistar rats were randomized equally into blank control group (A), model group (B), control treatment group (C) and treatment group (D). In groups B, C, and D, osteoporosis was induced by injection of prednisolone (8 mg/kg) via the tail vein 3 times a week for 12 consecutive weeks. After successful establishment of osteoporosis, allogenic ADSCs (3×10(6)/ml) were transplanted via the tail vein. The BMD at the L3-L5 levels and of the right femurs were detected, and the histomorphometry of the right tibias was analyzed in all the rats.
  
  
  RESULTS
  After prednisolone injection, the BMD of L3-L5 vertebrae and the right femurs, the percent trabecular area, trabecular thickness and trabecular number of the right tibias were all obviously lowered while the trabecular separation and osteoclast number increased in group B as compared to those in group A (P<0.05). Four weeks after ADSC transplantation, all these indices were significantly improved in group D, showing significant differences from those in group B (P<0.05) and also group C.
  
  
  CONCLUSIONS
  Transplantation of allogenic ADSCs can restore the BMD and bone histomorphometric properties of rats with GIOP, and may serve as a potential treatment for GIOP. These results also provide partial experimental evidence supporting the hypothesis of fasciaology.
