The invention is directed to a purified population of mammalian endothelial, muscle, or neural stem cells. New foliage of KASAI emerges predominantly White with a small amount of Green stippling apparent; as the foliage matures, foliage becomes predominantly Green in color, with some White mottling apparent and White margins; mature foliage is almost entirely Green in color though retaining White variegated margins and occasional White stippling. A heat spreader is soldered to the copper pattern, and the heat spreader is loaded with a semiconductor chip. The second housing component is attached to the first housing component and can close the opening of the housing space with the portions of the optical fiber members and the optical component connected to the optical fiber members housed in the first housing component.
