Abstract

Purpose of Review: Solid organ transplantation is limited by lack of suitable donor organs. Older and comorbid organs are frequently discarded on the basis that they will not withstand the overall process—principally the degree of ischemia reperfusion injury associated with preservation and transplantation. Interventions to prevent injury and promote regeneration are badly needed. Recent stem cells of multiple types including mesenchymal stem cells (MSCs) and adipose-derived regenerative cells (ADRCs) have been demonstrated to protect against tissue injury in multiple models relevant to transplantation. Recent Findings: Recent studies have improved our understanding of the multiple mechanisms underlying these beneficial effects including immunomodulatory and anti-inflammatory actions. Evidence suggests extracellular vesicular transfer of therapeutic factors, such as Sox9, cytokines, IL-17A, CCR2, and S1P has a key role in these effects. Summary: Several novel approaches such as stress treatments, culture techniques, and exogenous chemical manipulation show significant promise in improving the efficacy of stem cell populations in preventing tissue injury. There is even the possibility to harness the body’s own sources of such cells through interventions such as point-of-care fat modulation or mobilization of endogenous bone marrow-derived cells. The many unanswered questions and barriers to translating this promising technology to clinical transplantation are discussed.
