A recent study published in the journal stem cells raises a few questions on the appropriateness of using fat derived stem cells in clinical patients at this time. While the study injected fat derived mesenchymal stem cells with tumor cells (nothing any clinician would ever consider doing) and found that they created bigger tumors, it does raise a point that long-term MRI follow-up for tumor creation is needed. RSI has obtained that data over the past two years on the Regenexx procedure and is readying that for publication. What it shows is that MSC's grown with our proprietary technique do not promote tumor formation as measured by state of the art 3.0 T MRI imaging (images before and after the procedure). This is very important, as what we don't know is if cells grown with other procedures (for example one that requires exogenous growth hormones or other cells sources-fat instead of the Regenexx source of bone marrow) might promote tumor growth. We will be readying this data for publication over the next few weeks and hope to have this in the research lexicon by fall of this year.
