This book provides an in-depth exploration of the key concepts in developmental biology, offering a clear understanding of embryonic development. It explains frogs' complex developmental stages, from cleavage to tadpole stages, both externally and internally through diagrams, microscopic and pictorial images of permanent slides. Likewise, the exploration extends to chick embryos, carefully scrutinizing stages categorized by the Hamburger and Hamilton classification, providing information on advanced developmental milestones during incubation times. Moreover, the book provides a firsthand glimpse into the dynamic processes of embryogenesis by demonstrating chick embryo culture from fertilized eggs through pictures and videos. Furthermore, by observing the real time pictures of life cycle and developmental phases of Drosophila, Zebrafish, Caenorhabditis elegans, and Spodoptera litura which are cultivated from stock cultures, readers will obtain important knowledge on genetic and morphological changes. Moreover, detailed sections of the placenta, depicted through photomicrographs and slides, enrich the understanding of mammalian development.
This book is a useful resource for both undergraduate and postgraduate students in Life Sciences, as well as for teaching and research. It offers a comprehensive understanding of developmental processes and provides straightforward methods for maintaining model organisms in the laboratory for further exploration.

Prof. Alok Chandra Bharti, a Banaras Hindu University doctorate with 29 years experience in molecular oncology, conducted pioneering research at MD Anderson Cancer Center, Texas, on NF-B and STAT3 in carcinogenesis, diagnostics, and therapeutic targeting. Currently serving as professor at the Uni. of Delhi, Dr. Bharti held a Senior Scientist role at ICMRs National Institute of Cancer Prevention and Research for 12 years. He has published 104 international peer-reviewed papers and 20 book chapters, guided 19 Ph.D. students. His work focuses on developing affordable diagnostics for HPV-associated cancers and advancing research on cervical cancer stem cells, particularly in identifying circulating tumor cells as diagnostic markers. In 2008, he was nominated advisor to the WHO-HPV Laboratory Network. Prof. Bhartis accolades include the INSA Medal for Young Scientist (2009) and Senior Research Fellowships from ICMR and INSA (2012, 2018). He has the expertise in working with mouse and chick embryo models.
Dr. Anna Senrung is a faculty in the Dept. of Zoology at Daulat Ram College (DRC), Uni. of Delhi, with over 11 years of teaching and research experience. An active researcher, Dr. Senrung specializes in angiogenesis and the tumor microenvironment of Glioblastoma, utilizing chick embryos as a model system, and has authored four publications on chick embryo studies and culture apart from other publications in national and international journals as well as in conference proceedings.
