16.Define and briefly explain organ-specific angiogenesis? 17. Explain briefly the concept of stem cell. 18. What is AGM and what is its role? 19. What are hematopoietic inductive environments and what is their role in the differentiation of HSCs into different lineages?
20. What is derived from the endodermal germ layer? 21. Name three organs that develop as outgrowths of the early digestive system and name one function for each of these organs. 22. Amniote eggs have a variety of adaptations to development inside the mother’s body (or on land). For each of these adaptations state the germ layer origin(s) and the environmental problem it targets. 23. GENERAL QUESTION: Cells make multiple transitions during development between epithelial and mesenchymal states. There are also many examples of communication between epithelial and mesenchymal structures. Think about example(s) for each of these two different occurrences, and about itheir role in development. (Keep in mind that transitions are not the same as communications. First define transitions and communications; only when you become comfortable with the meanings of those words try to answer the question.)
