Postembryonic Fish Brain Proliferation Zones Exhibit Neuroepithelial‐Type Gene Expression Profile

Emilie Dambroise et al., STEM CELLS

This study provides an integrated view of neuroepithelial-like cells in the adult fish brain. These results challenge the widely-accepted view that adult neurogenesis relies on radial glia and will fuel discussions on the nature of extensive cell proliferation observed in these animals. As never reported before in vertebrates, the researchers show cells paused in G2, thereby pointing to novel pathways of quiescence control in stem cells, including for example the DNA repair machinery.



Donor‐Dependent and Other Nondefined Factors Have Greater Influence on the Hepatic Phenotype Than the Starting Cell Type in Induced Pluripotent Stem Cell Derived Hepatocyte‐Like Cells

James A. Heslop et al., STEM CELLS Translational Medicine

Current protocols for producing hepatocyte-like cells (HLCs) do not produce fully mature hepatocytes. Previous reports have suggested an improved phenotype may be yielded by using the incomplete resetting of the epigenome during induced pluripotent stem cell (iPSC) generation. We report the first comparison of iPSCs derived from human isogenic hepatocytes and fibroblasts for producing HLCs. We find little significant difference between iPSC-HLCs derived from hepatocytes and the easier to access and reprogram fibroblasts—an important finding for current and future studies which require patient specific (i.e., for transplantation) or disease/genotype specific phenotypes.



High Aldehyde Dehydrogenase Activity Identifies a Subset of Human Mesenchymal Stromal Cells with Vascular Regenerative Potential

Stephen E. Sherman et al., STEM CELLS

Applying core stem cell concepts using aldehyde dehydrogenase (ALDH) as a conserved marker of primitive progenitor cells, mesenchymal stromal cells (MSCs) appear to have a functional hierarchy where vascular regenerative potential is diminished as ALDH activity is reduced with cell differentiation. Purified ALDHlo and ALDHhi MSCs demonstrated clear secretory differences after purification, which correlated with endothelial cell activation in vitro and enhanced stimulation of proangiogenic processes in vivo. Thus, ALDHhi MSCs represent a proangiogenic MSC subset with regenerative potential applicable to the development of cell therapies to augment therapeutic revascularization.



Efficacy and Safety of Immuno-Magnetically Sorted Smooth Muscle Progenitor Cells Derived from Human-Induced Pluripotent Stem Cells for Restoring Urethral Sphincter Function

Yanhui Li et al., STEM CELLS Translational Medicine

This study provides a promisingly clinical-scale method for enriching committed cells from Human-induced pluripotent stem cells (hiPSCs) differentiation. Magnetic-activated cell sorting (MACS)-sorted smooth muscle progenitor cells (pSMCs) were heterogenous with negligible undifferentiated cells after in vitro directed differentiation. This cell population showed long-term tissue integration with no in vivo tumor formation. Furthermore, MACS-sorted pSMCs efficiently induced the remodeling of extracellular matrix of lower urinary tract and promoted functional recovery of the damaged urethra sphincter in a SUI animal model. These findings should facilitate translation of hiPSC-based cell therapy to clinical applications for smooth muscle regeneration.
