Special Issue Information

Dear Colleagues,

Early mammalian development is uniquely vulnerable to environmental, metabolic, inflammatory, oxidative, hypoxic, osmotic, and hormonal stressors because rapid proliferation and lineage decisions occur on a tight schedule. Even transient stress can shift developmental trajectories, alter trophoblast invasion and placental establishment, and reduce embryo viability—outcomes with implications in natural conception, assisted reproduction (IVF), and developmental toxicology. This Special Issue will showcase mechanistic and translational studies defining how stress sensing and response programs (e.g., kinase networks, unfolded protein response/integrated stress response, developmentally associated stress response, oxidative stress defenses, mitochondrial and metabolic checkpoints, epigenetic and transcriptomic remodeling) influence peri-implantation embryos, gastrulation-stage lineages, and stem-cell-based embryo models. We particularly encourage submissions using trophoblast/placental models (human EVT, trophoblast stem cells, organoids), naïve/primed pluripotent stem cells and embryoids/blastoids/gastroids, and high-throughput screening platforms for stress reduction or hazard identification. Topics of interest include single-cell and bulk multi-omics, live imaging, biomarker discovery (including non-invasive sampling), comparative human–mouse analysis, and interventions (small molecules/media optimization) that improve developmental embryonic and placental competence and function.

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.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Early mammalian embryos are highly sensitive to environmental, metabolic, hormonal, and genomic stress, yet embryo assessment during In Vitro Fertilization (IVF) relies largely on morphology and ploidy for embryo assessment, but these tests incompletely predict miscarriage. We present a transcriptomics based framework to classify and quantify lineage-specific stress in early embryos by benchmarking human preimplantation embryos against dose-, time-, and quality-dependent stress programs defined in Embryonic and placental Trophoblast Stem Cells (ESCs, TSCs) from the implanting blastocyst. Human embryos and stressed ESCs and TSCs are screened using transcriptomic markers from eleven biologically distinct stress Gene Ontology (GO) groups that define functional stress states and enable quantification of pathway presence and upregulation, pathway activity, and downstream outcomes. This framework determines whether the Integrated Stress Response (ISR), once initiated, resolves to enable the Developmentally Associated Stress Response (DASR). High-throughput screening (HTS) titrates stress to define increasingly risky yet biologically equivalent doses for levels of diminished stem cell growth across mechanistically diverse stressors. Then bulk RNA seq derives lineage specific transcriptomic markers putatively respond to common levels of diminished growth and that distinguish weak vs. strong stress and resolved vs. unresolved ISR. These stem cell transcriptomic signatures are applied to bulk RNA seq data from IVF embryos graded for morphology or adhesion, enabling quantitative inference of stress burden, lineage vulnerability, and developmental trajectory.
