    Abstract

    Spatio-Temporal Dynamics Enhance Cellular Diversity, Neuronal Function, and Further Maturation of Human Cerebral Organoids

    Investigators demonstrated two different engineering approaches, the rotating cell culture system microgravity bioreactor and a newly designed microfluidic platform to improve harvestability, reproducibility, and the survival of high-quality cerebral organoids and compare with those of traditional spinner and shaker systems.

    Abstract

    miR-23b-3p Regulates Human Endometrial Epithelial Cell Adhesion Implying a Role in Implantation

    Researchers investigated miR-23b-3p function during receptivity. qPCR and in situ hybridization were used to investigate the expression and localization of miR-23b-3p in human endometrium, respectively.

    Abstract

    Head and Neck Cancer Patient-Derived Tumoroid Cultures: Opportunities and Challenges

    To evaluate patients who will respond to a particular treatment, there is a need to develop in vitro model systems that replicate in vivo tumor status. Scientists discuss the challenges and opportunities for developing such systems to model head and neck tumor biology.
