Abstract: An apparatus for cutting a multilayer material includes a splitter module and a uniaxial crystal element. The splitter module, located in a transmission path of an incident light beam, is used for splitting the incident light beam into a first polarized light beam and a second polarized light beam. The uniaxial crystal element is disposed adjacent to the splitter module and on a transmission path of the first polarized light beam and the second polarized light beam. The first polarized light beam and the second polarized light beam pass through the uniaxial crystal element individually by having the first polarized light beam and the second polarized light in correspondence to different index of refractions, so that two focuses with different focal lengths can be obtained. In addition, a method for cutting a multilayer material method is also provided.

Abstract: The invention provides methods and compositions for differentiating stromal cells from adipose tissue into cells having osteoblastic properties, and methods for improving a subject's bone structure. The methods comprise culturing stromal cells from adipose tissue in ?-glycerophosphate and ascorbic acid and/or ascorbate-2-phosphate for a time sufficient to allow differentiation of said cells into osteoblasts. Such methods and compositions are useful in the production of osteoblasts for autologous transplantation into bone at a surgical site or injury. The compositions comprise adipose stromal cells, a medium capable of supporting the growth of fibroblasts and amounts of ?-glycerophosphate and ascorbic acid and/or ascorbic-2-phosphate sufficient to induce the differentiation of said stromal cells into osteoblasts. The invention further provides methods of identifying compounds that affect osteoblast differentiation.
