In this study, we evaluated the effect of the association of a bioactive glass-ceramic scaffold (Biosca) with mesenchymal stem cells derived from either bone marrow (BM-MSCs) or adipose tissue (AT-MSCs) on bone formation in calvarial defects of osteoporotic rats. Wistar rats were submitted to bilateral ovariectomy (OVX) or only to the surgical stress (Sham), under approval of the Committee of Ethics in Animal Research. After 5 months, 5-mm unilateral calvarial defect was creat...

Changes in the ability of self-renewal and differentiation of mesenchymal stem cells may be affected by osteoporosis. The aim of this investigation was to compare the transcriptional profile of mRNAs and miRNAs of osteoblastic cells from calvaria and bone marrow of female rats after ovariectomy. Following the approval by ethics committee, 18 wistar rats were divided into control (sham) and ovariectomized groups. After 150 days, both groups were sacrificed to collect the femurs...
