Module 5 problem: Developmental biologists did the following experiments to discover the role of endoderm in the specification of cardiogenic mesoderm. Using early mouse embryos:
Experiment 1 : Removed the anterior endoderm and cultured the embryo – no cardiogenic mesoderm and no heart muscle cells developed.
Experiment 2: Removed anterior endoderm and replaced it posterior endoderm from another embryo and cultured the embryo – no cardiogenic mesoderm and noheart muscle cells formed.
Experiment 3: Removed anterior endoderm and replaced it anterior endoderm from another embryo and cultured the embryo – cardiogenic mesoderm and heart muscle cells developed.
1.What are the signals that come from the anterior endoderm? 2. What is their role in specification of the cardiogenic mesoderm? 3. What signals come from the posterior endoderm? 4. What signals come from the neural tube/notochord? 5. What does the data mean?
Homework Answers
Answer-1 The signals for the synthesis of the cardiogenic mesoderm emerge from the endoderm.
Answer-2 they synthesize the cardiogenic mesoderm and the heart muscle cells.
Answer-3 it send signals for receptors for the pain and other stimulus.
Answer-4 the neural tube or notochord send signals for the functioning of all the three cardiogenic layers and their synthesis.
Answer-5 this data means that the endoderm plays a role in synthesis of cardiogenic mesoderm and heart muscle cells.

Describe cleavage and gastrulation in frogs. Then describe the steps in specifying the germ layers and the dorsal-ventral and anterior-posterior axis. Include cortical rotation at fertilization, endoderm specification including what is special about the dorsal vegetal cells (Nieuwkoop center), mesoderm induction including how dorsal mesoderm is induced, and the function of the organizer (dorsal lip of the blastopore). Describe the transplantation experiment that established the dorsal lip as the “organizer”. Also describe the experiments that were used to determine if...

3) The protein beta-catenin is a component of several different types of cellular events that we have studied thus far this semester. Give two examples of different roles that beta catenin can play in the regulation of cellular events during development 4) You are studying the development of two novel organisms that you have discovered. After fertilization you allow the embryo develop to the four cell stage. At that point you separate the four cells...

Developmental Biology Help! Please answer all the questions 1) We discussed the fact that each stripe expression pattern is affected by the enhancer region that is utilized. Knowing that the maternal genes and the gap genes can both contribute to the pair-rule genes, and that in many cases multiple stripes may be contained in one area of GAP, how does the embryo have definition of stripes if all of these transcription factors can be within the same cell A it...
