  • Stem cells have traditionally been characterized as either embryonic (pluripotent) or organ-specific. Recent work suggests that the latter can "transdifferentiate" into other cell types, carrying significant implications for possible clinical use of these cells. Here the authors critically examine the existing data, and suggest standards for the evaluation of these and future studies.

  • Despite a decade of intensive preclinical research, the translation of cancer nanomedicine to the clinic has been slow. Here, we discuss how recent lessons learned from the successes with immuno-oncology therapies could be applied to cancer nanomedicine and how this may help to overcome some of the key technical challenges in this field.

  • Using cells derived from human pluripotent stem cells for therapeutic applications carries a risk that rare undifferentiated cells in the transplant will give rise to teratomas. Tang et al. identify a new antigen on the surface of human pluripotent cells that, combined with other antigens, enables complete depletion of teratoma-initiating cells.

  • The development of a long-term intestinal culture system has, until recently, eluded researchers. Here the authors describe a method allowing long-term culture of both small intestine and colon that incorporates an air-liquid interface coupled with a three-dimensional matrix scaffold. The cultures show epithelial cell proliferation and multilineage differentiation to the major cell types and accurately recapitulate the Wnt- and Notch-dependent intestinal stem cell niche.

  • Normalization of the tumour vasculature can improve immune effector cell infiltration, leading to immunotherapy potentiation. In this Opinion article, Huanget al. propose that reciprocal regulation between tumour vascular normalization and immune reprogramming forms a positive feedback loop that can induce durable antitumour immunity within the tumour microenvironment.

  • There is much interest in the applications of pluripotent stem cells for regenerative medicine. In this Perspective, the authors discuss the factors that might contribute to the potential risk of tumorigenicity from pluripotent stem cell therapies. They also outline recent developments in techniques that allow the sorting of tumorigenic species from nontumorigenic cells and offer a viewpoint into the future hurdles for moving pluripotent stem cell–based therapies from bench to bedside.

  • Innate immune checkpoints, including those regulating tumour detection and phagocytosis, have emerged as potential cancer immunotherapy targets. This Review discusses the role of phagocytosis checkpoints in cancer immune evasion, highlighting the preclinical and early clinical evidence supporting phagocytosis checkpoint blockade.

  • A flow cytometry–based approach using eight surface markers is used to distinguish cells of the skeletal stem cell lineage. Renal subcapsular transplantation and in vitro colony-formation assays are also described for cell characterization.

  • Lineage tracing is a sophisticated technique to track cellsin vivo. Here, Paola Romagnani and colleagues describe how lineage tracing can be used to track the fate of cells involved in renal development, pathophysiological changes and regeneration. The authors discuss considerations in selecting an appropriate reporter, promoter, and activating switch for lineage tracing experiments, and approaches to data interpretation.
