VÝVOJOVÁ FYZIOLOGIE I •DEVELOPMENTAL BIOLOGY •- central to all other areas of biology – unites cell biology, genetics and morphology •- in last 25 years grew into the most exciting and dynamic field of biology…..due to the advances in three main traditions: the experimental embryology, developmental genetics and molecular biology. All animals develop similarly, that including the worm, fly, fish or mammal. •- significant impact on society, in vitro fertilization, teratology, birth defects. •- future impact: functional genomics and functional proteomics, disease therapy, prenatal screening, transplantation, embryonal stem cells, therapeutic cloning. • AMAZING NATURAL SPECTACLE AND A SOURCE OF INSPIRATION FOR ALL OTHER AREAS OF BIOLOGY YSL – yolk syncytial layer hypoblast epiblast - cell nuclei visualized using GFP-tagged histone-2B injection - 400000 images per embryo taken -app.18000 cells individually tracked in the 18-hours-old embryo - - SCIENCE 2008, 322, 1065-9
