Methods and apparatus for preserving tissue such as harvested organs for transplant are described. A preferred method includes delivering to a harvested organ an effective amount of electromagnetic energy, the electromagnetic energy having a wavelength in the visible to near-infrared wavelength range, wherein delivering the effective amount of electromagnetic energy includes selecting a predetermined power density (mW/cm2) of electromagnetic energy to deliver to the organ while in hypothermic or normothermic storage. A preferred apparatus includes a container having a cooling chamber to receive the harvested organ and at least one light source mounted on the container to illuminate the interior cooling chamber, said light source emiting light which produces a biostimulative effect on tissue placed in the cooling chamber thereby preventing or retarding damage to the tissue during storage or transport.

What is claimed is: 1. An apparatus for transporting living tissue, such as an organ, comprising: a tissue preserving container having at least one wall surrounding an interior chamber that receives a tissue, the at least one wall having a plurality of openings therethrough; and at least one light source mounted on the container and extending through the openings into the interior chamber so as to illuminate the tissue within the interior chamber from a multiplicity of directions during transport of the apparatus; said light source emitting optical radiation which produces a biostimulative effect on the tissue, thereby preventing or retarding damage to said tissue during transport. 2. An apparatus according to claim 1 wherein the light source emits optical radiation having a power density at the tissue of at least about 1 mW/cm2. 3. An apparatus according to claim 1 wherein the light source emits optical radiation having a power density at the tissue of about 2 mW/cm2 to about 20 mW/cm2. 4. An apparatus according to claim 1 wherein the light source emits optical radiation having a wavelength of about 630 nm to about 904 nm. 5. An apparatus according to claim 4, wherein the radiation has a power density at the tissue of about 0.1 mW/cm2 to about 20 mW/cm2. 6. An apparatus according to claim 1 wherein the light source is an LED. 7. An apparatus according to claim 1, wherein the light source emits optical radiation having a wavelength of about 780 nm to about 840 nm. 8. An apparatus according to claim 7, wherein the radiation has a power density at the tissue of about 0.1 mW/cm2 to about 20 mW/cm2. 9.

An apparatus according to claim 1, wherein the transport of the apparatus is for a period of at least four hours. 12. An apparatus according to claim 1, wherein the at least one light source mates with each opening to form a fluid tight seal. 13. An apparatus according to claim 1, further comprising a secondary container having a plurality of walls, the secondary container configured to suspend the interior chamber in a thermoregulatory fluid. 14. An apparatus according to claim 13, wherein the at least one light source extends from the plurality of walls and mates with the openings to form a fluid tight seal against the thermoregulatory fluid. 15. An apparatus for transporting living tissue, such as an organ, comprising: a container comprising a hollow chamber that retains tissue and at least one wall surrounding the chamber, the at least one wall having a plurality of openings therethrough; and a plurality of light sources extending through the openings and within the chamber so as to illuminate the tissue within the chamber from several directions during transport of the apparatus; wherein said light sources emit optical radiation having a wavelength of about 630 nm to about 904 nm which produces a biostimulative effect on tissue, thereby preventing or retarding damage to the tissue within the chamber during transport. 16. An apparatus according to claim 15 wherein the light sources emit optical radiation having a power density at the tissue of about 0.1 mW/cm2 to about 20 mW/cm2. 17. An apparatus according to claim 15, wherein the light sources emit optical radiation having a wavelength of about 780 nm to about 840 nm. 18.
