Complete suspension culture of human induced pluripotent stem cells supplemented with suppressors of spontaneous differentiation

This study develops a suspension culture method for hiPSCs using PKCβ and Wnt inhibitors to prevent spontaneous differentiation, enabling scalable and stable clinical-grade hiPSC production.

Iron regulatory pathways differentially expressed during Madurella mycetomatis grain development in Galleria mellonella

This study identifies iron regulatory pathways involved in Madurella mycetomatis grain formation in Galleria mellonella using time-course transcriptomic profiling.

Triangulation reduces the polygon of error for the history of Transeurasian

The paper addresses critiques of a Transeurasian language and population history study by revising datasets and methods, showing that the original findings remain valid despite objections.

F-actin regulates polarized secretion of pollen tube attractants in Arabidopsis synergid cell.

This study shows F-actin is essential for polarized secretion of attractants in Arabidopsis synergid cells, affecting pollen tube guidance.

Cellular dynamics of endosperm development in Arabidopsis thaliana

The paper characterizes the cellular dynamics of coenocytic endosperm development in Arabidopsis thaliana using live-cell imaging and genetics, revealing roles of cytoskeleton components in nuclear movement and seed size control.

Comparative transcriptomic analysis reveals conserved transcriptional programs underpinning organogenesis and reproduction in land plants

This study generates gene expression atlases for 10 plant species to identify conserved transcriptional programs in organogenesis and reproduction, revealing gene co-option as a key mechanism for organ evolution.

Estrogenic action by tris(2,6-dimethylphenyl) phosphate, an impurity in resorcinol bis flame retardant formulations, impairs the development of female reproductive functions

This study shows that TDMPP, an estrogenic flame retardant impurity, affects female reproductive functions by altering brain development in mice.

Development of the Brief Personal Values Inventory for sense of values in the Japanese general population

The paper develops a shorter questionnaire, BPVI, to assess sense of values in Japanese adults, showing it aligns with Schwartz's value theory and is suitable for comparing values across age groups.

A shared cis-regulatory module activates transcription in the suspensor of plant embryos

The paper shows that the same cis-regulatory motifs control transcription of two suspensor-specific genes, G564 and GA 20-oxidase, in Scarlet Runner Bean embryos, though motif arrangement differs.

Collaborative environmental DNA sampling from petal surfaces of flowering cherry Cerasus ×- yedoensis 'Somei-yoshino' across the Japanese archipelago

The paper collects and analyzes environmental DNA from petal surfaces of cherry trees across Japan, showing rapid DNA attachment and the presence of other plant DNA, supporting the use of petals for studying environmental DNA dynamics.
