The Critical Role of Enhanced OXPHOS and Mitochondrial Hyperpolarization in Simulated Microgravity‐Induced Oocyte Maturation Arrest

open access: yesAdvanced Science, Volume 12, Issue 38, October 13, 2025.
Simulated microgravity induces distinct mitochondrial hyperactivation patterns‐elevated OXPHOS and MMP‐which accelerate meiosis without SAC failure but delays MTOC coalescence, leading to spindle defects and meiotic arrest. Prolonging M‐phase restores MTOC assembly and oocyte maturation.

Nanostructured Biomaterial‐Based Approaches to Support Induced Pluripotent Stem Cell Differentiation

open access: yesAdvanced NanoBiomed Research, Volume 5, Issue 10, October 2025.
Induced pluripotent stem cells (iPSCs), reprogrammed from adult somatic cells, represent an innovative approach for regenerative medicine and biomedical applications. This review highlights the importance of nanostructured biomaterials, utilized as delivery systems or scaffolds, in supporting iPSC differentiation and fate through structural and ...

Interleukin 1 Signaling Is Regulated by Leukemia Inhibitory Factor (LIF) and Is Aberrant in Lif−/− Mouse Uterus [PDF]

open access: yes, 2008
This study addresses the regulation of the interleukin 1 (IL1) system in the murine uterine luminal epithelium (LE) and stroma by leukemia inhibitory factor (LIF). Using RT-PCR we compared expression of Il1a, Il1b, Il1rn, Il1r1, and Il1r2 during the pre-

A Barrier to Understanding Teratogenicity: The Critical Periods of Sensitivity for Most Structural Birth Defects Precede the Established Hemochorial Placenta

open access: yesBirth Defects Research, Volume 117, Issue 10, October 2025.
ABSTRACT Background Teratogens and other environmental factors influence human birth defect risk, but our understanding of how they reach the developing conceptus is surprisingly limited. The placenta is often invoked as a key mediator of teratogenicity by acting as a physical barrier that can block or regulate the transfer of harmful substances to the
