Bone grafts and constructs including stem cells are provided. Example bone grafts include osteogenic stem cells seeded on a scaffold of osteoconductive cortico-cancellous chips and/or osteoinductive demineralized bone. Example constructs include extracellular matrix on a synthetic scaffold, in which the ECM is secreted from MSCs seeded onto the synthetic scaffold. Also provided are methods of making the present bone grafts and scaffolds. Further provided are methods of promoting bone healing and treating wound healing, by administering the present bone grafts and constructs to a mammal in need thereof. Also provided are kits that include the present bone grafts and/or constructs, or components thereof.

A cultureware system is directed to maintaining viability of mammalian cells, and includes a disposable holding container having a cell receiver with a cell-receiving surface. The cell receiver consists of a cell-adhesion inducement material including a polystyrene material and a glass material. The system further includes a polytetrafluoroethylene (PTFE) coating lining the cell-adhesion inducement material of the cell-receiving surface, and a culture of adherent mammalian cells located within the cell receiver on the PTFE coating. In response to attachment interaction between the mammalian cells and the PTFE coating, a decreased cell adhesion results in a cell viability rate of at least about 60% to about 70% over a 72-hour culturing period, the cell viability rate being under 90% over the 72-hour culturing period if, in the absence of the PTFE coating, the mammalian cells are located directly on the cell-adhesion inducement material.

A tissue engineered three-dimensional model and related processes and apparatus. The model includes a three-dimensional porous ceramic template including a plurality of primary macro-pores; and cells cultured in the three-dimensional porous ceramic template, wherein at least some of the cells form one or more three-dimensional cellular matrices in the primary macro-pores. A process for preparing a tissue engineered three-dimensional model includes the steps of preparing the three-dimensional porous ceramic template, including a plurality of primary macro-pores; and culturing cells in the three-dimensional porous ceramic template, wherein at least some of the cells form one or more three-dimensional cellular matrices in the primary macro-pores.

A 3D in vitro bi-phasic cartilage-bone organoid includes a layer of an artificial cartilage tissue, and a layer of an artificial bone tissue comprising a structure-giving scaffold and a bone marrow structure. The layer of the artificial cartilage tissue contacts at least one surface of the layer of the artificial bone tissue.

A pharmaceutical active ingredient for cell differentiation to alleviate cell and cell-related deficiencies in mammals comprising porous silica containing a releasable agent capable of contributing to a cell environment conducive for stem cell differentiation in co-implanted stem cells and/or in endogenous stem cells.
