Opioids are one of the oldest analgesics used to relieve pain. Besides their therapeutic properties, they also have negative side effects, which include impaired tissue regeneration. Therefore, it can be assumed that opioids also have a negative effect on stem cells which are responsible for tissue healing. One of stem cell populations involved in wound regeneration are mesenchymal stem cells (MSCs). MSCs are undifferentiated, multipotent cells that could be find in almost all tissues. They have immunoregulatory properties and they can migrate to the site of inflammation or injury where they contribute to healing of tissues. Therefore, the purpose of this thesis was to evaluate the effect of morphine and methadone on properties and migration of MSCs. Their effect on the metabolic activity of MSCs and also on the production of cytokines and growth factors was measured. The effect of these opioids on the immunoregulatory properties of MSCs acting on both innate and adaptive immune cells in vitro was studied. The effect of morphine on expression of adhesive molecules on MSCs was also examined. Furthermore, the effect of morphine on migration properties of systemically administered exogenous MSCs in vivo was investigated in mouse models. Distribution of MSCs to individual organs and to the site of...
