Isolation of Precursor B-cell Subsets from Umbilical Cord Blood

Md Almamun¹, Jennifer L. Schnabel¹, Susan T. Gater², Jie Ning¹, Kristen H. Taylor¹

¹Department of Pathology and Anatomical Sciences, University of Missouri-Columbia, ²Laboratory for Infectious Disease Research, University of Missouri-Columbia

Here we describe a protocol for isolating subsets of precursor B-cells from umbilical cord blood. A sufficient quantity and quality of nucleic acids may be extracted from the cells and used in subsequent assays utilizing DNA or RNA.

Photothrombosis-induced Focal Ischemia as a Model of Spinal Cord Injury in Mice

Hailong Li^*1, Gourav Roy Choudhury^*1, Nannan Zhang¹, Shinghua Ding¹

¹Department of Bioengineering, Dalton Cardiovascular Research Center, University of Missouri

Photothrombosis is a minimally invasive and highly reproducible procedure to induce focal ischemia in the spinal cord and serves as a model of spinal cord injury in mice.

Working memory predicts a significant amount of variance for a variety of cognitive tasks, including speaking, reading, and writing. However, few tools are available to assess working memory in children. We present an innovative, computer-based battery that comprehensively assesses different components of working memory in school-age children.
