The present invention relates generally to a method of using light treatment to maintain a specific cell type in a subject. Specifically, the present invention relates to methods for promoting cell proliferation, migration, differentiation and survival using specific parameters of light. These methods are particularly useful for cell regeneration and replacement in tissue injury such as CNS or PNS injury, and transplantation of organs, tissues and cells. A composition for treating a disease or condition in a subject comprising neural stem cells, neural progenitor cells or mesenchymal stem cells, having a wavelength of 200-1500 nm and a power density of 1-100 mW / cm 2. Providing a composition comprising exposing the cells to light stimulation performed with light having the light stimulation, wherein the light stimulation promotes cell differentiation or proliferation.
