This February during American Heart Month, the NIH is encouraging people to take charge of their health and start new, heart-healthy behavior that can help reduce their risk of heart disease and stroke. For more information, visit the NIH’s official website:

The MMRRC is now maintaining two exciting new lines with broad applicability and interest to scientists working in many different areas. These mouse lines are called “Mouse for Actively Recording Cells 1” or MARC1. Donated by Dr. George M. Church, Ph.D., and Dr. Reza Kalhor, Ph.D., of Harvard Medical School, they are used for barcoding and lineage tracing applications in the mouse (PMID:30093604). Although these lines do not express any disease-related phenotypes, when a MARC1 mouse is crossed to mice expressing cas9 (universally or in a lineage-specific manner), combinatorial and cumulative barcoding starts in the progeny during their development, leading to developmentally barcoded animals that can be used for a multitude of applications, including lineage tracing.
The available lines are:

The MMRRC is the nation’s premier national public repository system for mutant mice. Funded by the NIH continuously since 1999, the MMRRC archives and distributes scientifically valuable spontaneous and induced mutant mouse strains and ES cell lines for use by the biomedical research community. The MMRRC consists of a national network of breeding and distribution repositories and an Informatics Coordination and Service Center located at 4 major academic centers across the nation. The MMRRC is committed to upholding the highest standards of experimental design and quality control to optimize the reproducibility of research studies using mutant mice. The MMRRC is supported by the Office of Research Infrastructure Programs (ORIP) in the Office of the Director at NIH. More than 50,000 mutant alleles are maintained as live mice, cryopreserved germplasm, and/or mutant ES cells. Live mice are supplied from a production colony, from a colony recovered from cryopreservation, or via micro-injection of ES cells. An MMRRC facility may offer cryopreserved material for resuscitation at the recipient scientist's institution.
