Abstract: By analyzing hematopoietic stem cell proliferation regulators produced by stroma cells, a cDNA library is constructed and novel hematopoiesis-associated genes are isolated. Genes encoding the proteins as specified in the following (a) or (b): (a) having an amino acid sequence represented by one of SEQ ID NOS selected from the group consisting of SEQ ID NOS: 2, 4, 6, 8, 10 and 12; or (b) having an amino acid sequence derived from the amino acid sequence as defined in the above (a) by deletion, substitution or addition of one to several amino acids and having an activity of regulation hematopoietic stem cell proliferation.

Abstract: A novel method for joining edge portions of electromagnetic wave shielding members is proposed. A joiner is prepared by solder-plating a surface of a narrow strip of electromagnetic wave shielding material of a metal foil or a metal sheet. The respective edge portions of adjacent electromagnetic wave shielding members made of metal sheets or metal foils are butted against each other. The solder-plated surface of the prepared joiner is superposed on the respective abutting edge portions of the electromagnetic wave shielding members. Thereafter, while the joiner is being pressed against the shielding members by a heater, the joiner is solder-welded to both of the electromagnetic wave shielding members via the solder-plated layer.
