Summary
Purpose of Review
Mesenchymal stem or stromal cells (MSCs) are a heterogeneous group of non-hematopoietic, multipotent progenitor cells that share a multitude of similarities with fibroblasts and other cell types. The question of how to distinguish MSCs from other cell types lacks a definitive answer. Here, we discuss the differences and similarities between MSCs and other cell types with regard to their cellular characteristics, origins, and immune interactions. Furthermore, the distribution of MSCs and their regional effects within the body are outlined.
Recent Findings
We give insights into the current methods to track MSC distribution and homing within the body and review the mode of action of MSC therapy. The local and systemic effects of MSC therapy and possible alternatives such as the application of MSC-derived vesicles are also discussed.
Summary
Important mechanisms regarding MSC therapy are not yet completely understood. This review provides insights into the current methods used to better understand these issues, which is a prerequisite for the clinical application of MSC-based therapies.

This shows that patient-specific MSCs can be obtained from fibroblasts in large amounts by a direct conversion into induced MSCs, which could open novel ways for MSC-based therapies.
