Commentary: The International Mouse Phenotyping Consortium: High-Throughput In Vivo Functional Annotation of the Mammalian Genome
Lloyd, Mammalian Genome. 2024.

The International Mouse Phenotyping Consortium (IMPC), a collectively governed consortium of 21 academic research institutions across 15 countries on 5 continents, represents a groundbreaking approach in genetics and biomedical research. Its goal is to create a comprehensive catalog of mammalian gene function that is freely available and equally accessible to the global research community. So far, the IMPC has uncovered the function of thousands of genes about which little was previously known. By 2027, when the current round of funding expires, the IMPC will have produced and phenotyped nearly 12,000 knockout mouse lines representing approximately 60% of the human orthologous genome in mice. This new knowledge has produced numerous insights about the role of genes in health and disease, including informing the genetic basis of rare diseases and positing gene product influences on common diseases. However, as IMPC nears the end of the current funding cycle, its path forward remains unclear. Supported by ORIP (UM1OD023221).
Lesion Environments Direct Transplanted Neural Progenitors Towards a Wound Repair Astroglial Phenotype in Mice

Neural progenitor cells (NPCs) are potential cell transplantation therapies for central nervous system (CNS) injuries. Investigators derived NPCs expressing a ribosomal protein-hemagglutinin tag (RiboTag) for transcriptional profiling. Their findings reveal similarities between the transcriptional profiles, cellular morphologies, and functional features of cells transplanted into subacute CNS lesions and host astroglia. The astroglia are stimulated by injuries to proliferate and adopt a naturally occurring, border-forming wound repair phenotype in mice of both sexes. Understanding the autonomous cues instructing NPCs transplanted in CNS host tissue will be fundamental to therapeutic NPC transplantation.
