    Abstract: An aggregated cell evaluation apparatus includes a laser light source, a speckle image acquisition unit, an SC calculation unit, an evaluation unit, and a memory unit. The speckle image acquisition unit acquires a two-dimensional speckle image by forward scattered light generated in aggregated cells by irradiation of the aggregated cells with laser light output from the laser light source. The SC calculation unit calculates a speckle contrast value Kn of a speckle image In at each time tn, determines a maximum value Kmax among the speckle contrast values K1 to KN, and normalizes the speckle contrast value Kn at each time tn by the maximum value Kmax to obtain a normalized speckle contrast value Kn′. The evaluation unit evaluates motion of the aggregated cells, based on the normalized speckle contrast value Kn′ at each time tn.

    Abstract: A method for observing stem cells by an observation device 1 comprises, placing stem cells C in a petri dish 11, mounting the petri dish 11 on a waveguide 21 via water 13, emitting illumination light L1 into the waveguide 21 and emitting the illumination light L1 to the stem cells C in the petri dish 11 via the water 13, and detecting scattered light L2, the scattered light L2 being the illumination light L1 emitted to the stem cells C that is scattered by the stem cells C and has passed through the waveguide 21. Then, in the light image detected by means of the scattered light L2, a region that is markedly darker than other regions is identified as being in the state tending toward differentiation.
