Special Issue Information

Dear Colleagues,

The early stages of mammalian embryonic development are characterized by a series of finely coordinated molecular and cellular events that determine the success of implantation and subsequent growth. Small alterations in these early processes can lead to impaired embryo viability and development. Understanding the molecular bases of these mechanisms is essential to identifying mechanisms underlying reproductive success and to reveal how disturbances lead to developmental defects or pregnancy loss.

Recent advances in molecular and cell biology are helping to uncover how gene expression, epigenetic regulation, and signaling pathways interact with metabolism and oxidative balance to support cell division, differentiation, and communication during early development. This Special Issue aims to gather original research and review articles that advance our understanding of the molecular and cellular mechanisms that affect the first stages of mammalian embryonic development. By integrating molecular, metabolic, and physiological perspectives, this Special Issue aims to integrate fundamental and translational insights, contributing to a deeper understanding of the factors that determine embryonic health and developmental success. We encourage researchers to submit manuscripts sharing molecular signalling, metabolic pathways, mitochondrial function, oxidative stress, or experimental models related to early embryos and developmental competence.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cells is an international peer-reviewed open access semimonthly journal published by MDPI.

Embryos being treated using assisted reproductive technology (ART) are unavoidably exposed to physical stressors, thus producing reactive oxygen species (ROS) which trigger mitophagy to support embryonic development. However, the mechanisms underlying the regulation of mitophagy in early embryonic development remain largely unexplored. Here, we found that Mucin 1 (MUC1) exhibited a uniform distribution in both mouse and human oocytes, and its expression peaked at the blastocyst stage. Further analysis revealed that Muc1 knockout impairs blastocyst formation in vitro. Correspondingly, Muc1 knockout led to the accumulation of mitochondrial reactive oxygen species (mtROS) and a reduction in phosphatase and tensin homolog (PTEN)-induced putative kinase 1 (PINK1)/Parkinson protein 2 (PARK2/Parkin)-dependent mitophagy. Stimulation of mitophagy via low-dose carbonyl cyanide 3-chlorophenylhydrazone (CCCP) treatment rescued the blastocyst formation defect in Muc1-null embryos. Vitamin C supplementation effectively scavenged mtROS and restored developmental competence. Together, our findings establish that MUC1 safeguards early embryonic development by promoting mitophagy to decrease mtROS levels in vitro. Moreover, vitamin C could compensate for Muc1 deficiency by eliminating mtROS. This study not only identified a new function of MUC1 in protecting early embryonic development in vitro, but also revealed a novel mechanism of mitophagy regulation in early embryos, which has potential applications for ART.
