Dendritic cells (DCs), and more recently lymph node stromal cells (LNSCs), have been described to tolerize self-reactive CD8(+) T cells in LNs. Although LNSCs express MHCII, it is unknown whether they can also impact CD4(+) T cell functions. We show

We have assessed the utility of an intracellular fluorochrome, 5-(and-6)-carboxyfluorescein diacetate succinimidyl ester (CFSE), as a tracking label for human intervertebral disc cells in vitro. Although 5 microM provides adequate intracellular labeling for whole cell fluorescent microscopic identification of labeled
