A blood reservoir () for storing blood includes a first storage section (), a second storage section (), and a third storage section () that is provided between the first storage section and the second storage section, and communicates with the first storage section and the second storage section. A volume of the blood reservoir () can be adjusted by changing the amount of expansion or contraction of a bellows structure () using a bellows adjustment mechanism ().

A method for preparing serum and a serum preparation apparatus is provided that can give a large amount of serum with high culture efficiency regardless of freshness of blood used. In a method for preparing serum from blood containing at least platelets, a platelet processing step is provided in which platelet membrane in the blood is destroyed. After the platelet processing step, a deposition step for depositing thermolabile protein in blood and a removal step for removing the thermolabile protein, which has been deposited in the deposition step, are preferably provided.

The present invention provides a method for controlling the proliferation and differentiation of cord blood-derived hematopoietic stem cells with excellent safety when proliferating them by culturing. The hematopoietic stem cells are inoculated into a medium containing a sonicated liquid component of cord blood. The proliferation and differentiation of the cord blood hematopoietic stem cells can be inhibited in the presence of the sonicated liquid component of cord blood. On the contrary, the proliferation of cord blood hematopoietic stem cells can be accelerated by inoculating the hematopoietic stem cells into a medium containing a non-sonicated liquid component of cord blood. Thus, according to the present invention, by using serum derived from cord blood, it is possible to regulate the inhibition of the proliferation and differentiation of cord blood hematopoietic stem cells and the acceleration of the proliferation of the same as desired.

A process for producing a porous body with different physical properties in desired regions is provided by pore forming treatment, not by bonding two or more materials made porous beforehand, with, for example, an adhesive. Raw materials are prepared, each of which contains a polymer and a raw material preparation solvent. At least two types of the raw materials having different compositions are prepared. Thereafter, the respective raw materials are frozen into desired shapes to form frozen bodies thereof. The frozen bodies thus formed are brought into contact with each other to form an assembly thereof, the assembly is exposed to a condition under which the frozen bodies begin to melt, and the assembly is then freeze-dried. Thus, a porous body having regions different in physical properties can be obtained. Such a porous body can be used as, for example, an adhesion inhibitory material or a scaffold for a cell culture.
