Cultured cells are generally observed through the bottom of dishes or flasks using an inverted microscope. Two-dimensional and horizontal observation is insufficient for histological analysis of several cell lines, such as embryonic stem cells or cancer cells, because they form three-dimensional colonies. In the present study, we aimed to establish a more informative method for analysis of such stereoscopic cultured cells. We cultured mouse embryonic stem cells using a temperature-sensitive culture dish, embedded these cells in paraffin, and successfully observed vertical sections of embryonic stem cells. This vertical analysis of the stereoscopic colony emphasized structural features such as the dome shape of naïve pluripotent stem cells. This method could have the potential for analysis of three-dimensional structures and histological preservation in cultured cells.
