Abstract: A novel method for producing a bone filling material is provided. The method comprises the steps of: (a) kneading ingredient comprising calcium-based material and material comprising binder; (b) molding a predetermined shape of the mixture obtained in step (a) with an injection molding machine having a mold; (c) removing the binder contained in the mold formed in step (b) (i.e., degreasing) to obtain a degreased body; (d) and heating and sintering the degreased body obtained in step (c) to obtain a sintered body.

Abstract: The present invention provides a cell picking tool, etc. The present invention relates to a molded body for cell collection (cell picking tool) with a concave structure capable of picking a cell sheet which has been two-dimensionally cultured in a culture container while keeping the sheet form without using a cell dispersant, wherein by placing the molded body for cell collection so as to come in contact with a cell assembly in a cell growth environment, a liquid component for cell growth (cell growth environment) is incorporated therein and cells can be collected in the concave structure while keeping the cells in a state of aggregation; and a method of handling the same.
