Abstract
AbstractBased on clinical observations, stroke is touted as one of the specific pathological conditions, affecting an individual’s life worldwide. So far, no effective treatment has been introduced to deal with stroke post-complications. Production and release of several neurotrophic factors by different cells exert positive effects on ischemic areas following stroke. As a correlate, basic and clinical studies have focused on the development and discovery of de novo modalities to introduce these factors timely and in appropriate doses into the affected areas. Exosomes (Exo) are non-sized vesicles released from many cells during pathological and physiological conditions and participate in intercellular communication. These particles transfer several arrays of signaling molecules, like several neurotrophic factors into the acceptor cells and induce specific signaling cascades in the favor of cell bioactivity. This review aimed to highlight the emerging role of exosomes as a therapeutic approach in the regeneration of ischemic areas.

Abstract
Stem cell tourism is an emerging area of medical tourism activity. Frustrated by the slow translation of stem cell research into clinical practice, patients with debilitating conditions often seek therapeutic options that are not appropriately regulated. This review summarises recent developments in the field of stem cell tourism and provides clinicians with the information necessary to provide basic pretravel health advice to stem cell tourists. PubMed and Scopus databases were consulted for relevant publications, using combinations of the terms 'stem cell', 'tourism', 'regenerative medicine', 'international', 'travel medicine' and 'environmental health'. The leading countries in the international stem cell tourism market are the USA, China, India, Thailand and Mexico. As the majority of clinics offering stem cell therapies are based in low- and-middle-income countries, stem cell tourists place themselves at risk of receiving an unproven treatment, coupled with the risk of travel-related illnesses. These clinics do not generally provide even basic travel health information on their websites. In addition to often being ineffective, stem cell therapies are associated with complications such as infection, rejection and tumorigenesis. Physicians, researchers, regulatory bodies, advocacy groups and medical educators are encouraged to work together to improve patient and physician education and address current legislative deficiencies.

Challenging misinformation and engaging patients: characterizing a regenerative medicine consult service. Regen Med 2020; 15:1427-1440. [PMID: 32319855 PMCID: PMC7466910 DOI: 10.2217/rme-2020-0018] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2020] [Accepted: 03/19/2020] [Indexed: 02/06/2023] Open
Abstract
Aim: To address the unmet needs of patients interested in regenerative medicine, Mayo Clinic created a Regenerative Medicine Consult Service (RMCS). We describe the service and patient satisfaction. Materials & methods: We analyzed RMCS databases through retrospective chart analysis and performed qualitative interviews with patients. Results: The average patient was older to elderly and seeking information about regenerative options for their condition. Patients reported various conditions with osteoarthritis being most common. Over a third of consults included discussions about unproven interventions. About a third of patients received a clinical or research referral. Patients reported the RMCS as useful and the consultant as knowledgeable. Conclusion: An institutional RMCS can meet patients' informational needs and support the responsible translation of regenerative medicine.
