BACKGROUND The unique potential of mesenchymal stromal cells (MSC) has generated much research interest recently, particularly in exploring the regenerative nature of these cells. Previously, MSC were thought to be found only in the BM. However, further studies have shown that MSC can also be isolated from umbilical cord blood, adipose tissue and amniotic(More)
BACKGROUND The multipotency of stromal cells has been studied extensively. It has been reported that mesenchymal stromal cells (MSC) are capable of differentiating into cells of multilineage. Different methods and reagents have been used to induce the differentiation of MSC. We investigated the efficacy of different growth factors in inducing MSC(More)
We investigated the sequence of expression of osteoblast gene markers during bone formation in vivo by in situ hybridization. Cylindrical lesions were induced in the femora of sheep with titanium analytic bone implants that allow removal of serial core samples to study bone formation. At 2 weeks (2W), granulation tissue made up of spindle-shaped cells had(More)
The influence of TGF beta 1 on bone was studied in a titanium device implanted into the tibia of rabbits. TGF beta 1 was infused via an Alzet osmotic pump calibrated to deliver at a rated of 200ng daily for 2 weeks before replacement. A hollow channel is incorporated into the device into which tissue can grow, and the histological sequence of events was(More)
