Phoenix-R is committed to the highest standards of safety and quality in the sourcing and processing of exosomes. We partner with leading U.S.-based laboratories that follow strict regulatory guidelines and quality control protocols. Ongoing research into mesenchymal stem cells (MSCs), also known as mesenchymal stromal cells or medicinal signaling cells, explores their potential role in cellular processes and tissue interactions. Donors who meet strict eligibility criteria are further tested in laboratories that comply with CLIA standards, following established safety and quality protocols.
