Fig. 1. Conservation of zinc finger domains of Osr1 and Osr2 in vertebrates. (A) Amino acid sequence alignment of Osr1 using MafftWS sequence alignment reveals high conservation of the zinc finger binding domains. B) Amino acid sequence alignment of Osr2 using MafftWS sequence alignment reveals high conservation of zinc fingers 1–3 in all species. Zinc fingers 4 and 5 are only conserved in chick, mouse, and humans. Zinc finger domains 1–3 and 4–5 are indicated by red and purple bars, respectively, shown above the amino acid sequence of interest. OSR2B, the alternatively spliced protein product has only been identified in mammals and was therefore omitted from the protein conservation analysis. Conservation is depicted below the corresponding amino acid sequence.

Fig. 2. According to the traditional concept of mesenchyme, during embryonic development, mesenchymal-like tissues form through EMT from epithelial-shaped tissues in two major steps at the early stages of gastrulation. Specifically, the primary mesenchyme originates from the epiblast to form mesoderm and primitive endoderm; this process is regarded as the prototype of EMT. Subsequently, the mesoderm reverts to an epithelial morphology to generate transient embryonic structures, including somites, which then undergo a further round of EMT to generate secondary mesenchyme. Secondary mesenchyme is considered the embryonic connective tissue and provides the precursors of the connective tissues of the adult body.

Mirco Galiè summarizes studies that support the hypothesis that the partially or fully mesenchymal phenotype might represent a general paradigm of stem cell plasticity underlying embryonic development, regenerative potential, as well as their pathological counterparts: https://bit.ly/3JADAW0

September/October cover of Differentiation. Fluorescence micrograph of Drosophila melanogaster testis tip. Merged testis image displays DAPI (yellow), anti-Mettl3 (cyan) and anti-Vasa (magenta) stains. Nuclear DAPI stain in combination with antibody against m6A methyltransferase Mettl3 and germline marker Vasa, indicates localization pattern of methyltransferase in cells of the apical tip during spermatogenesis.

Fig. 6. WNT5b mediates the Pi-induced suppression of OS cells migration. (A) Transwell assay was performed to evaluate the migration ability of NOS-10 (5 days) and SJSA-1 (10 days) cells with knock-down of WNT5b by siRNAs treated with osteogenic supplement medium. The analyses were performed at 24 h after seeding the cells into the culture inserts (n = 4). Scale bar = 500 μm.

Yuya Suzuki et al. evaluated the ability of two types of Pi (i.e., disodium phosphate [Na2HPO4] and monosodium phosphate [NaH2PO4]) to promote the osteogenic differentiation of osteosarcoma cells. Learn more: https://doi.org/10.1016/j.diff.2025.100912
