  • Patent number: 9506035
    Abstract: The present invention generally relates to methods, compositions and uses thereof for enhancing vascularization of a tissue or cell transplant for transplantation into a subject. In particular, one aspect of the present invention provides methods and compositions comprising the use of a population of stromal vascular fraction (SVF) cells to encapsulate or surround a tissue or cell transplant to enhance vascularization of the tissue or cell transplant. Another aspect of the present invention provides methods and compositions for enhancing vascularization of a tissue or cell transplant by combining a population of SVF cells with a tissue or cell transplant to form a transplant mixed with SVF cells. In some embodiments, the SVF cells can be on the surface or embedded within a three-dimensional matrix. In some embodiments, the SVF cells can be generically engineered to secrete therapeutic proteins or pro-angiogenic factors.

  • Publication number: 20160201027
    Abstract: Methods of making a spheroid are provided whereby a suspension is first produced including one or more biologically-relevant materials dispersed within a biocompatible medium. A droplet of the suspension is then bioprinted into a salt solution by bringing the droplet into contact with a surface of the salt solution in a controlled manner to reproducibly yield a spheroid containing a desired size and a desired amount of biologically-relevant materials.

  • Publication number: 20150004199
    Abstract: Cell delivery matrices and methods for facilitating local delivery of adipose derived endothelial cells to a target tissue, body cavity, or joint are described. The cell delivery matrix may be a three-dimensional matrix scaffold comprising fibrin derived from the patient's own body. The cell delivery matrix may be biocompatible and semi-permeable. The cell delivery matrix used in the methods of the invention may be comprised of any degradable, bioabsorbable or non-degradable, biocompatible polymer. Regenerative therapies comprising implanting in the subject cell delivery matrices localizing adipose derived endothelial cells are described. The cell delivery matrices maintain the adipose derived endothelial cells at the target for a therapeutically effective amount of time. The adipose derived endothelial cells can be allogenic or syngenic to the subject. The endothelial cells may be delivered alone or in combination with other therapeutic agents.

  • Patent number: 8202725
    Abstract: Tissue engineering methods and biochamber apparatus are provided for making tissue grafts for implantation into a patient. The methods include applying a sustained low magnitude pressure gradient transmurally across a permeable scaffold material using a media containing cells, preferably microvascular epithelial cells, to be deposited on the scaffold for the production of tissue grafts, preferably vascular grafts, to promote accelerated adhesion and maturation of cells on the scaffold material. Biochambers for preparing tubular tissue grafts are provided which contain connectors for holding a graft substrate, proximal and distal tubing for connection to an optional perfusion system, and structure for switching between transmural flow of a cell suspension across the graft substrate and translumenal flow through the lumen of the graft.
