Quality testing is pertinent to having a product that is effective, safe, and uncompromised throughout manufacturing. This section describes specifically the testing results of pathogen gauging prior to shipping and after low passage expansion in our lab. Additionally the specifications are listed for a variety of trait variables in the lower half of this page. Our CLIA lab partner can test final cells and grade RUO or GMP upon customer request.
Research shows that UC-MSCs are superior to bone marrow stem cells in terms of risks of rejection, contamination, and infection. They also outperform bone marrow in their ability to replace damaged cells and have a lower risk of graft-vs-host disease (GVHD) due to their immunoprivileged characteristics.
Umbilical Chord (UC)-MSC from Regenerelle are characterized by immunofluorescence with antibodies specific to CD73, CD90 and CD105. UC-MSC are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and fungi.
Regenerelle documents the batch-to-batch consistency and reproducibility of the cells.
