Exploring Tissue Engineering: Vitamin D3 Influences On The Proliferation And Differentiation Of An Engineered Osteoblast Precursor Cell Line During Early Bone Tissue Development, Shelley S. Mason
Dissertations and Theses
Most of the load-bearing demand placed on the human body is transduced by skeletal tissue, and the capacity of the skeleton to articulate in various opposing directions is essential for body movement and locomotion. Consequently, cartilage and bone defects due to trauma, disease, and developmental abnormalities result in disabling pain and immobility for millions of people worldwide. A novel way of promoting cartilage and bone regeneration is through the incorporation of either primary cells or multipotent progenitor cells in a three-dimensional (3D) biomaterial scaffold, and/or the addition of exogenous growth and differentiation factors. The first part of this study reports …
Osteoinductivity Of Demineralized Bone: A Quantitative In Vitro Assessment, Yihong Zheng
Osteoinductivity Of Demineralized Bone: A Quantitative In Vitro Assessment, Yihong Zheng
Biological Sciences Theses & Dissertations
Acid demineralized bone (DMB) implanted in extraosseous sites induces bone formation. In vivo studies have shown that DMB stimulates the differentiation of mesenchymal cells into osteogenic cells. In this study an in vitro system was developed to demonstrate the osteoinductivity of DMB quantitatively. This in vitro working system was used to assess the osteoinductivity of variously processed DMB products as a means to evaluate their processing protocols. A human dermal fibroblastic (HDF) cell line was initiated from tissue explants as a working model, along with a human periosteal (HPO) cell line as a control. Ground DMB processed by LifeNet Transplant …
