Cytologic and Histological Features Distinguishing Myxoid Meningioma From Chordoid Meningioma: A Case Report

Diagnostic Cytopathology, EarlyView.
ABSTRACT Meningiomas are the most common primary brain tumors worldwide and are classified into 15 subtypes in the 5th edition of the WHO classification. Myxoid meningioma, characterized by the presence of a mucinous matrix within the tumor, is a rare metaplastic meningioma subtype classified as WHO grade 1.

Diagnostic Utility of Ki‐67 Index on Cell Block Material for Grading Medullary Thyroid Carcinoma

Diagnostic Cytopathology, EarlyView.
ABSTRACT Introduction An international grading system for medullary thyroid carcinoma (IMTCGS) was established in 2022. High‐grade MTC is defined by the presence of one or more of the following features: mitotic index ≥ 5 per 2 mm2, Ki‐67 proliferative index ≥ 5%, or tumor necrosis.

Insights into embryonic chromosomal instability: mechanisms of DNA elimination during mammalian preimplantation development

Frontiers in Cell and Developmental Biology
Mammalian preimplantation embryos often contend with aneuploidy that arose either by the inheritance of meiotic errors from the gametes, or from mitotic mis-segregation events that occurred following fertilization.

A comprehensive embryonic staging series of the turtle Trachemys scripta

Developmental Dynamics, EarlyView.
Abstract Background Turtles hold a unique place in vertebrate evolutionary history, making them critical assets in embryology research. Yet, they remain understudied as potential model organisms in the field. Here, to support experimental manipulations with turtle embryos, we have created a complete normal table of development for comprehensive ...

Differential sensitivity of midline development to mitosis during and after primitive streak extension

Developmental Dynamics, EarlyView.
Abstract Background Midline establishment is a fundamental process during early embryogenesis for Bilaterians. Midline morphogenesis in non‐amniotes can occur without mitosis, through Planar Cell Polarity (PCP) signaling. By contrast, amniotes utilize both cellular processes for developing the early midline landmark, the primitive streak (PS).

Robinow syndrome DVL1 variants disrupt morphogenesis and appendage formation in a Drosophila disease model

Developmental Dynamics, EarlyView.
Abstract Background Robinow syndrome is a rare developmental syndrome caused by variants in genes in Wnt signaling pathways. We previously showed that expression of patient variants in Dishevelled 1 (DVL1) in Drosophila and chicken models disrupts the balance of canonical and non‐canonical Wnt signaling.

Expression of mutant TIE2 p.L914F during mouse development causes embryonic lethality and defects in vascular remodeling

Developmental Dynamics, EarlyView.
Abstract Background Sporadic venous malformation (VM) is associated with the hyperactivating p.L914F mutation in TIE2, a receptor tyrosine kinase essential for vascular development. This mutation is not found in hereditary VM, suggesting incompatibility with life when expressed during early vascular development.

Oogenesis and germinal bed morphology of the brown anole (A. sagrei)

Developmental Dynamics, EarlyView.
Abstract Background The brown anole is a model species of the genus Anolis, a squamate (encompassing lizards and snakes) group widely studied in evolutionary, behavioral, and developmental biology. Full genome annotation, the establishment of gene editing techniques, and comprehensive description of reproductive tract morphology and embryogenesis in ...

PSMA‐Targeting Macrophage Membrane‐Coated Nanoparticles for Precision Diagnosis and Combination Therapy of Prostate Cancer

Exploration, EarlyView.
Advanced prostate cancer is highly invasive and prone to rapid metastasis, creating an urgent need for novel therapeutic strategies. We developed a PSMA‐targeting macrophage membrane‐coated nanomedicine (P‐MMCNPs@DM1). Leveraging the immune‐evasive and active‐targeting properties of macrophage membrane coating, P‐MMCNPs@DM1 effectively managed both ...
