Abstract: Stimulating tissue resident pluripotent stem cells in a manner that the respective subject (e.g., human) acts as its own sterile bioreactor for in vivo stem cell proliferation thus eliminating the need to isolate, cultivate, maintain, proliferate and release stem cells ex vivo. The stimulation mobilizes excess pluripotent stem cells into the peripheral vasculature where the pluripotent stem cells can either migrate to damaged tissues and/or be harvested by simple venipuncture, thus eliminating potential morbidity and mortality elicited from harvesting tissue from solid tissue sites. The pluripotent stem cells are separated from the blood by gravity sedimentation, after which the pluripotent stem cells can easily be aspirated from the white blood cells and red blood cells. Billions of pluripotent stem cells can be generated in this fashion for infusion/injection into the body, via the vasculature, and into the organ(s) in need of tissue repair and regeneration.

Abstract: A medical practitioner can specify certain parameters for a procedure that involves delivering a therapeutic agent, while leaving other parameters open. The therapeutic agent can be sensitive to biomechanical forces (or other influences) associated with delivery. The procedure can involve regenerative medicine, for example delivering progenitor or stem cells to a diseased heart using a catheter, whereby unbridled transport in the catheter may compromise efficacy. The open parameters can influence efficacy of the agent and thus therapeutic outcome. A computer-based system can apply stored information, such as from databases, to narrow the possible values of the open parameters. From the narrowed possibilities, an optimization routine can determine suitable or optimized values for the open parameters. The determined values can manage biomechanical forces incurred by the therapeutic agent, thereby promoting efficacy and healing. The optimized parameters can guide the practitioner in the procedure.

Abstract: For the repair of a cartilage defect in a human or animal patient use is made of an implant comprising an implant body including a natural cartilage matrix and being coated with cells having a chondrogenic potential. These cells are produced by in vitro cell proliferation starting from chondrocytes isolated from a cartilage biopsy.

The cells adhering to the surface of the implant body are preferably also chondrocytes being de-differentiated by cell proliferation, but not re-differentiated, and are therefore particularly suitable for integrating the implant in the defect. Due to the cells adhering to the surface of the implant body, the implant is successfully integrated in the viable tissue surrounding the defect.
