The purpose of the invention is to provide novel cell culture substrates, cell culture vessels, and methods for cell culture. A cell culture substrate having a planar mesh structure, the substrate being coated with a polymer, is provided. Cells are cultured in a cell culture vessel having this substrate.

A microchannel has a substrate body; a separation channel which is formed within the substrate; at least two (first and second) connection ports which are formed at one end of the separation channel close to the thickness direction perpendicular to the longitudinal direction of the substrate body; and first and second branch channels connected respectively to the first and second connection ports. When the substrate body is perpendicular to gravity, a blood sample containing blood cells and plasma, flows from one end of the separation channel. Before the blood sample gets to the other end of the separation channel, the blood cells in the blood sample settle out. The blood cells having settled out are then separated into the branch channel.

Microchannel for separating blood plasma

An optical scanning apparatus including an optical system of refracting an illumination light illuminated from a light source device by a scanning lens into parallel optical beams and condensing the light by a condensing lens located at a focal position of the scanning lens on an observed surface, in which the light source device has a light emission portion attached to a stage which is adjustable for the position along an XY plane in perpendicular to the optical axis of the scanning lens, with an optical axis of irradiation light being in parallel with the optical axis of the scanning lens. The apparatus being small in the size and simple in the structure, capable of easily controlling the spot position, not requiring accurate optical axis alignment and manufactured at a reduced cost.
