Stem cellⁱ biology is highly topical and is attracting great interest not only within the research community but also from politicians, patient groups and the general public. However, the standard of publications in the field is very variable. Papers that are scientifically flawed or comprise only modest technical increments often attract undue profile. At the same time publication of truly original findings may be delayed or rejected.

Medical travel for unproven stem-cell-based therapies is commonly referred to as stem cellⁱ tourism. Clinics worldwide over-promise the benefits of their so-called treatments and grossly downplay or ignore the risks. Such unproven therapy is without scientific rationale. Neither the efficacy of the treatments, nor the lack of serious side effects has been shown in animal models. This 'magic cure by stem cells' approach must be condemned under all circumstances.
