This subproject is one of many research subprojects utilizing theresources provided by a Center grant funded by NIH/NCRR. The subproject andinvestigator (PI) may have received primary funding from another NIH source,and thus could be represented in other CRISP entries. The institution listed isfor the Center, which is not necessarily the institution for the investigator.For this Core, one prime function is to provide state-of-the-art capabilities for the isolation and analysis of progenitor cell populations based on immunological, genetic, physical and/or metabolic properties. These capabilities are of particular importance in working with rare stem and progenitor cell populations, but also find excellent application in cell and biomedical investigations at-large. This Core is now equipped with dedicated instruments for the isolation (or depletion) and analysis of such cell types. This includes a Becton Dickinson FACS-Calibur flow cytometer, a new FACS-Aria cell sorter, and Miltenyi MACS System (Automated Magnetic Cell Sorter) (with each purchased via Institute matching fund mechanisms). Additional users are Institute- wide, including investigators in MMCRI's Vascular Biology COBRE. As emphasized in recent NIH study section critiques, Core B is a critically important and highly productive component of our Stem Cell COBRE Center. It also has been an important tool for our successful recruiting efforts. Recently, Core B has developed a parallel resource for investigations involving the use of embryonic stem (ES) cells. In particular, certain services, technical support, and hands-on training for ES cell research are provided. Specified Collections of mouse ES cells and NIH-approved human ES cell lines are maintained with appropriate quality assurances. Support further includes instruction in ES cell maintenance, transduction, and differentiation. This Core component also provides a service of short-term culture and manipulation of ES cells for individual investigators, plus ready access to ES cell reagents (RNA, genomic DNA, protein preparations).
