Over the last few years, the generation of induced pluripotent stem cells (iPSCs) from human somatic cells has proved to be one of the most potentially useful discoveries in regenerative medicine. iPSCs are becoming an invaluable tool to study the pathology of different diseases and for drug screening. However, several limitations still affect the possibility of applying iPS cell-based technology in therapeutic prospects. Most strategies for iPSCs generation are based on gene delivery via retroviral or lentiviral vectors, which integrate into the host's cell genome, causing a remarkable risk of insertional mutagenesis and oncogenic transformation. To avoid such risks, significant advances have been made with non-integrative reprogramming strategies. On the other hand, although many different kinds of somatic cells have been employed to generate iPSCs, there is still no consensus about the ideal type of cell to be reprogrammed. In this review we present the recent advances in the generation of human iPSCs, discussing their advantages and limitations in terms of safety and efficiency. We also present a selection of somatic cell sources, considering their capability to be reprogrammed and tissue accessibility. From a translational medicine perspective, these two topics will provide evidence to elucidate the most suitable combination of reprogramming strategy and cell source to be applied in each human iPSC-based therapy. The wide variety of diseases this technology could treat opens a hopeful future for regenerative medicine. Copyright © 2015 John Wiley & Sons, Ltd.

Asphyxia leads to sudden hypoxia and hypercapnia with tissue hypoxia and progressive bradycardia. Standard CPR is not able to maintain an adequate tissue oxygenation during CPR in this animal model. When ROSC is achieved, a rapid restoration of the normal values of general hemodynamic and respiratory parameters is observed, although lactic acidosis and splanchnic hypoperfusion persist in time.
