Stem cells are also responsible for tissue turnover and repair in adults, and as such, they hold tremendous promise for regenerative therapy.

Paradoxically, the patients who would benefit the most from regenerative therapies are usually advanced in age. The use of stem cells from young donors or the rejuvenation of aged patient-derived stem cells may represent part of a solution. Nonetheless, the transplantation success of young or rejuvenated stem cells in aged patients is still problematic, since stem cell function is greatly influenced by extrinsic factors that become unsupportive with age.

I also thank Samantha M. Portis, Managing Editor of Cell Medicine, for the detailed editing of our articles. I am very sure that the relationship between Cell Medicine and JSOPMB has enhanced the motivation of JSOPMB members as well as board members and will continue to do so in the future, while also encouraging young Japanese researchers to join this organization. One of the extremely important missions of the annual meeting of the JSOPMB is to exchange new research outcomes and create new therapeutic concepts. The JSOPMB always encourages and motivates young investigators. The JSOPMB was founded in 1974 for the study of organ preservation and developed widely in the 1990s with the participation of researchers in various fields, including medicine, pharmacology, engineering, veterinary medicine, and basic science. Currently, the JSOPMB has more than 700 members and is run under the direction of Professor Takashi Kenmochi, the president of the JSOPMB. Excellent presentations from the 43rd annual meeting of the JSOPMB, held between 26–27 November 2016, in Tokyo, Japan, under the supervision of Dr Toshihiko Hirano (Professor, Department of Clinical Pharmacology, Tokyo University of Pharmacy and Life Sciences, Tokyo, Japan), were selected and given an opportunity to be published in this special issue of Cell Medicine. Five of these presentations are herein published in this special JSOPMB issue. Onoshima et al. developed a microfluidic chip for depositing single cells in micro-wells using simple micropipette operation. The chip will serve as a tool for single-cell patterning in an easy-to-use manner. Miyamoto et al. investigated the effects of temperature during long-term storage (8 years at 80 C and in LN2 phase) on the quality of various cells (HepG2, HH, NIH3T3, and STO cells) using culture medium containing 10% dimethyl sulfoxide (DMSO), Cell Banker 1, and Cell Banker 2. Among these solutions, Cell Banker 1 showed the highest efficiency. Stem cell research was a major topic of interest. There were two articles regarding stem cells. Miyagi-Shiohira et al. showed the development of cancer through induced pluripotent stem cell (iPSC) technology. They generated ‘induced fibroblast-like (iF) cells’ by the transient overexpression of reprogramming factors. Although the morphology of iF cells were fibroblastic, iF cells are unlikely to show adipogenic/ osteogenic differentiation. Moreover, iF cells have the ability to form tumors and behave similarly to pancreatic cancer cells. The technology used in the generation of iPSCs is also associated with the risk of generating cancer-like cells.

An endothelial cell line (C2BBe1) and a neuronal cell line (SHSY5Y) near confluency in media with 10% FBS were selectively scraped and taken through a 25-day step-wise algorithm to replace FBS, and another human endothelial cell line (HRA-19) was studied to replicate C2BBe1. Cells were stained, counted, and compared for viability, migration, and spheroids. The C2BBe1 and HRA-19 cell lines failed to proliferate in 10% Cell-Ess® but grew in 10% GroPro® or 10% FetalGro® reasonably well compared to reference 10% FBS. With SH-SY5Y, only FetalGro® approached FBS's efficacy. These were all inferior to 11 different branded lots of FBS (positive controls), but five days into switching just amongst the FBS brands, 4 of 11 supported less proliferation than reference FBS in endothelial HRA-19 (<i>p</i> < 0.004). Moreover, neurospheres were enriched in two branded lots of FBS and FetalGro® (each <i>p</i> < 0.004), neurospheres being an unwanted phenotype for any neuronal cell application. Because platelet-derived GroPro® stood out amongst the non-FBS growth supplements to allow proliferation without inducing spheroids, it seems the best (mindful that the cells still grew slower in it compared to FBS).
