Abstract: The invention provides a method or promoting healing of a wound, e.g., an epithelial wound, in an animal. The method involves administering cultured autologous fibroblasts to the wound.

Abstract: Methods of producing human stem cells are disclosed for parthenogenetically activating human oocytes by manipulation of O2 tension, including manipulation of Ca2+ under high O2 tension and contacting oocytes with serine threonine kinase inhibitors under low O2 tension, isolating inner cell masses (ICMs) from the activated oocytes, and culturing the cells of the isolated ICMs under high O2 tension. Moreover, methods are described for the production of stems cells from activated oocytes in the absence of non-human animal products, including the use of human feeder cells/products for culturing ICM/stem cells. Stem cells produced by the disclosed methods are also described.

Abstract: The present invention provides a method of using autologous fibroblasts to promote wound or fistula healing in an animal.

Abstract: The success of tissue transplantation, when immunological conflict is minimized, depends on the vascularization process. This process is very complex and requires time. During this time, transplanted tissue often has difficulty obtaining oxygen and nutrients. These factors have a profound influence on the survival of the transplanted tissue, especially if the tissue has poor angiogenic properties. For new vessel formation, endothelial cells from existing recipient microvessels must proliferate and migrate through the extracellular matrix into the transplanted tissue. However, if transplanted tissue is mixed with recipient endothelial cells or co-administered, vascularization and acceptance of auto-, allo-, and heterotransplants is enhanced. In addition, recipient endothelial cells can be used to enhance vascularization of three-dimensional tissue-engineered constructs.

These factors have a profound influence on the survival of the transplanted tissue, especially if the tissue has poor angiogenic properties. For new vessel formation, endothelial cells from existing recipient microvessels must proliferate and migrate through the extracellular matrix into the transplanted tissue. However, if transplanted tissue is irradiated with low-power laser, vascularization and acceptance of auto-, allo-, and heterotransplants is enhanced.
