“A Short Book on Organizers and Molecular Biology in Human Embryology” offers a concise yet comprehensive exploration of the molecular mechanisms governing early human development. It delves into the pivotal role of embryonic organizers, signaling pathways, transcription factors, and gene regulation that orchestrate cellular differentiation and organogenesis. Tailored for medical students, educators, and researchers, this book simplifies complex concepts in developmental biology and bridges the gap between classical embryology and cutting-edge molecular insights.
