Abstract: A method of culturing a cell population containing cartilage-derived cells positive for expression of Tie2 (cartilage-derived Tie2-positive cells), the method including culturing a cell population containing cartilage-derived Tie2-positive cells in a culture medium containing at least one kind of Tie2 expression enhancer other than growth factors (e.g., an extract derived from a plant of the genus Cinnamomum). This culturing method is preferably performed in cultureware having a culture surface coated with a coating agent (e.g., a polylysine-containing agent).

Abstract: A medical sheet has a cell infiltration suppressing action, including a nonwoven fabric formed of fiber containing an aliphatic polyester, and having a porosity of 50 to 90%. The sheet is very useful because it has an excellent neuroprotective and/or nerve regeneration promoting action, which protects nerves by suppressing the infiltration of inflammatory cells such as macrophages and not giving stimulation that adversely affects nerves because body fluids pass therethrough, by winding around a nerve at a peripheral nerve injury site.

Abstract: It is an object of the present invention to provide an extract from inflamed skins of rabbits inoculated with vaccinia virus wherein the quality is more stabilized, and a preparation containing the extract, etc. The use of the amount of N-acetylneuraminic acid contained in an extract from inflamed skins of rabbits inoculated with vaccinia virus and a preparation containing the extract as an index makes possible to warrant the quality of each manufacturing lot of the extract and the preparation in more stable manner. The extract from inflamed skins of rabbits inoculated with vaccinia virus and the preparation containing the extract which are manufactured as above, and in which the quality thereof becomes more stable, are warranted to maintain efficacy and safety in more strict manner, and thus extremely useful.
