    Background aims: Monocytes, derived from hematopoietic stem cells (HSCs), play a pivotal role in the immune response to cancer. Although they are an attractive source of cell therapy for cancer, a method for ex vivo expansion has not yet been established. Monocytes differentiated from pluripotent stem cells (PSCs), including induced pluripotent stem cells (iPSCs), can be an alternative source of HSC-derived monocytes because of their self-renewal and pluripotency. To develop a standardized method for the generation of iPSC-derived monocytes for future clinical applications, we aim to control the size of the iPSC colony. Methods: To this end, we developed a plate with multiple dots containing a chemical substrate for the iPSC scaffold. iPSCs placed in the plate expanded only on the dots and created colonies of the same size. The cells were then differentiated into monocytes by adding cytokines to the colonies. Results: The dot plate substantially reduced variability in monocyte-like cell generation when compared with cultivating cells on a plate with the substrate covering the entire surface area. Furthermore, more monocyte-like cells were obtained by adjusting the dot size and the distance between the dots. The iPSC-derived monocyte-like cells phagocytosed cancer cells and secreted proinflammatory cytokines. The cells also expressed Fc receptors and exerted immunoglobulin G-mediated killing of cancer cells with the corresponding antibodies. Conclusions: The dot plate enabled the control of iPSC colony size in two-dimensional culture, which resulted in a reduction in the generation-variation of functional monocyte-like cells. This standardized method for generating iPSC-derived monocyte-like cells using the dot plate could also facilitate the development of an automated closed system on a large scale for clinical applications.

    The laboratory culture of human stem cells seeks to capture a cellular state as an in vitro surrogate of a biological system. For the results and outputs from this research to be accurate, meaningful, and durable, standards that ensure reproducibility and reliability of the data should be applied. Although such standards have been previously proposed for repositories and distribution centers, no widely accepted best practices exist for laboratory research with human pluripotent and tissue stem cells. To fill that void, the International Society for Stem Cell Research has developed a set of recommendations, including reporting criteria, for scientists in basic research laboratories. These criteria are designed to be technically and financially feasible and, when implemented, enhance the reproducibility and rigor of stem cell research.
