A method of isolating epithelial cells from a human skin tissue or internal organ tissue using trypsin and ethylenediamine tetraacetic acid (EDTA) simultaneously with the application of magnetic stirring, a method of preconditioning isolated biological cells by the application of physical stimulus, i.e., strain, are provided. Epithelial cells can be isolated by the method with increased yield, colony forming efficiency (CFE), and colony size. Also, the increased percentage of stem cells in isolated cells is advantageous in therapeutic tissue implantation by autologous or allogeneic transplantation. In skin cells preconditioned by the application of strain, cell division is facilitated, and the secretion of extracellular matrix components and growth factors and the activity of matrix metalloproteinases (MMPs) are improved. When preconditioned cells are implanted by autologous or allogeneic transplantation to heal a damaged tissue, the improved cell adhesion, mobility, and viability provides a biological adjustment effect against a variety of stresses or physical stimuli which the cells would undergo after implantation, with improved capability of integration into host tissue, thereby markedly improving the probability of success in skin grafting.

Methods and compositions are provided for the treatment and repair of defect in the cartilage in partial- or full-thickness defects in joints of animals, in particular humans. To induce cartilage formation, a defect in cartilage is filled with layers of thin flaps of synovium or of peritendineum, which contains chondro- and osteo-progenitor cells, with interposed layers of a matrix. The matrix contains a chondrogenic factor, which induces chondrogenesis of chondroprogenitor cells in the flaps, and an anti-hypertrophic agent, which arrest differentiation of chondrocytes in an early phase, in an appropriate delivery system. The matrix filling the bone area of a full-thickness defect may contain an osteogenic factor, which induces osteogenesis of osteoprogenitor cells. The layer of a flap between cartilage and bone areas may work as a barrier, which prevents blood vessels and associated cells from penetrating from the bone area into the cartilage area. To promote the induction of chondro- and osteo-genesis of the progenitor cells in the flaps of synovium or peritendineum effectively, the flaps may be treated with enzymes, e.g., matrix metalloproteinases or be punched by a needle before filling a defect.
