Human multilineage-differentiating stress enduring (Muse) cells, a novel nontumorigenic pluripotent-like stem cell population, reside in the bone marrow, skin and adipose tissues, and can be collected as cells positive for stage-specific embryonic antigen-3 (SSEA-3), a surface marker for human embryonic stem cells. There are approximately 1% of SSEA-3-positive Muse cells in bone marrow-derived mesenchymal stem cells (BM-MSCs) [Ref.1]. Thus, we investigated the effects of locally administered human Muse cells on bladder tissues, function and nociceptive behavior in a chemically induced interstitial cystitis (IC)-like rat model.
