Emerging Research Frontiers
✗ Explicitly Out of Scope
Clinical Infertility Management
Excluded: IVF success rates, ICSI protocols, patient selection criteria, clinical outcome studies, treatment algorithms.
Rationale: These are clinical practice topics, not mechanistic embryology. Consider reproductive medicine or clinical journals.
Obstetric Care & Prenatal Diagnosis
Excluded: Prenatal screening protocols, ultrasound diagnostics, maternal-fetal medicine, pregnancy management, delivery outcomes.
Rationale: Focus is on embryonic development mechanisms, not clinical pregnancy management. Consider obstetrics journals.
General Inflammation & Disease Pathology
Excluded: Peripheral arterial disease, general inflammatory mechanisms, adult disease pathology, non-developmental pathology.
Rationale: Unless directly linked to embryonic development mechanisms, general pathology is out of scope. Consider pathology journals.
Ethical & Social Policy Discussions
Excluded: Embryo adoption policies, sex selection ethics, cloning debates, purely philosophical discussions without experimental data.
Rationale: JE publishes experimental research, not policy analysis. Consider bioethics or social science journals.
Adult Stem Cell Therapy Applications
Excluded: Clinical stem cell therapy outcomes, adult tissue regeneration protocols, therapeutic applications without developmental context.
Rationale: Focus is on embryonic stem cells and developmental mechanisms, not clinical regenerative medicine. Consider stem cell therapy journals.
