MSCs also secrete various factors to reduce proinflammatory cytokine such IL-6 and TNF α that may be useful for treating inflammatory diseases such as cystic fibrosis lung disease. MSCs can inhibit proliferation of T cell from lymph nodes of encephalomyelitis, reduce IFN- γ production by T cell, and significantly inhibit total antigen specific IgG production, as well as that of each IgG subclass. Recently, researchers reported immunomodulation effect of MSCs in experimental autoimmune disease. Therefore, many therapies were performed using autologous SVF rather than autologous or allogeneic MSCs. Moreover, the procedure is less expensive. Autologous SVF extraction procedure replaces any need for allogeneic cell culturing, and therefore risks of contamination, aging of stem cells, or rejection can be avoided.
Culturing SVF leads to MSC isolation, and 1-2 week-culture period is needed to produce millions of these fibroblast-like plastic adherent cells known as MSCs.
After lipoaspirate processing, MSCs are obtained along with endothelial cells, macrophages, pericytes, and T cells, which together comprise a substance referred to as stromal vascular fraction (SVF), in a relative short time, usually in 2-3 hours. MSCs are particularly useful for regenerative healing because they are multipotent cells, which can differentiate into a variety of cell types. Mesenchymal stem cells (MSCs) can be isolated from adipose tissue from patients through a simple liposuction technique.
#SUPER MARIO 64 LAST IMPACT INJECTED WAD TRIAL#
Our results showed that administration of high dose of SVF until 10 billion cells in a majority of 421 patients through infusion, spinal, and intra-articular injection was feasible without causing major adverse events and should be further investigated in well-designed phase I-II clinical trial to address the safety and efficacy of therapy. Any observed adverse events were identified as a result of spinal or intra-articular injections and were not related to SVF or PRP. Adverse events were not severe and were treated successfully. Cell dose that was considered to be safe was less than 10 billion SVF cells in 250 cc of normal saline, for IV injection, and less than 1 billion SVF, for intra-articular and spinal injection. The cell doses and adverse events for each patient were documented and analyzed. The type of intervention was determined by each disease evaluation. A minority group within the population received an additional spinal or intra-articular injection. Autologous PRP and SVF were administered to all subjects by intravenous (IV) injection. In addition, blood was drawn from each patient, and PRP was isolated. The lipoaspirate was treated with a tissue-dissociating enzyme, and then, through centrifugation, SVF was isolated. This study aimed to determine the safety of SVF and PRP that were given through infusion, spinal, and intra-articular injection. Autologous SVF, which is a substance containing stem cells, was isolated from lipoaspirate, mixed with platelet-rich plasma (PRP), and administered to patients with degenerative diseases, autoimmune diseases, trauma, aging, and other diseases with unknown etiology. Stromal vascular fraction (SVF) therapy has been performed over the past six years to treat 421 patients by our group in five clinical centers.
