Issue Information

Cover Photograph: Top left: Modeling autosomal dominant polycystic kidney disease (ADPKD) using kidney organoids derived from disease‐specifi c human induced pluripotent stem cells (hiPSCs) (see Shimizu et al., pp. 166–177 ). Top right: Differentiation from human embryonic stem (ES) cells into multiple anterior pituitary lineages (see Ozaki et al., pp. 154–165 ). 2nd left: The recapitulation of the vertebrate segmentation clock in vitro (see Diaz‐Cuadros & Pourquie, pp. 140–153 ). 2nd middle: Synthetic embryology systems expand the research of early embryonic development (see Tomoda & Kime, pp. 116–126 ). 2nd right: Model of the primitive endoderm/epiblast (PrE/EPI) lineage segregation in mouse preimplantation embryos (see Toyooka, pp. 127–139 ). 3rd left: Culture for large‐scale production of human induced pluripotent stem (iPS) cell‐derived platelets (see Nakamura et al., pp. 178–186 ). 3rd right: The type of pluripotent stem cells depends on the developmental stage of pre‐ and postimplantation embryos (see Semi & Takashima, pp. 104–115 ).
