    摘要： The present invention provides a process for differentiation of vascular endothelial progenitor cells from embryoid bodies derived from embryonic stem cells, the process comprising: (a) treating a culture medium comprising embryoid bodies derived from embryonic stem cells such that the concentration of oxygen dissolved in the culture medium is in the range of about 1 ppm to about 5 ppm; (b) culturing the culture medium prepared in step (a) in an incubator in which the oxygen (O2) tension is equal to or less than about 15% to differentiate the embryoid bodies into vascular endothelial progenitor cells; and (c) isolating the vascular endothelial progenitor cells from the culture medium obtained in step (b).

    摘要： An anti-doming composition including a mixture of electron reflecting material such as bismuth oxide, and a zeolite, and a shadow-mask coated with the composition restrict temperature increase by preventing heat transfer, an anti-doming composition including lead and a ZnO, B2O3, Bi2O3 or a mixture thereof, and a shadow-mask coated with the composition protect mechanical expansion of a shadow-mask, and an anti-doming composition including ferroelectrics such as PZT, PT, PZ or PLZT, and a shadow-mask coated with the composition restrict temperature increase by changing the energy of electron beams into non-thermal energy. The shadow-mask of the present invention reduces about 30 to 50% of the anti-doming ratio and has a low production cost and easiness during processes.
