Why can't we regenerate limbs? Why can only females have babies? Simi larly, a geneticist might ask how globin genes are transmitted from one generation to the next, and a physiologist might ask about the function of globin proteins i n the body.
But the developmental biologist asks how it is that the globin genes come to be expressed only in red blood cells, and how these genes become active only at specific times in development. We don't know the answers yet. Each field of biology is defined by the questions it asks. Welcome to a wonderful set of importa nt questions! The Questions of Developmental Biology Development accomplishes two major objectives.
About this book
Put another way, there 'are two fundamental questions in developmental biology. How does the ferti lized egg give rise to the adult body? And how does that adult body produce yet another body? A single cell, the fertilized egg, gives rise to hundreds of different cell types-muscle cells, epidermal cells, neurons, lens cells, lymphocytes, blood cells, fat cells, and so on.
Resynthesizing evolutionary and developmental biology.
The generation of this cellular diversity is called differentiation. Since every cell of the body with very few exceptions contains the same set of genes, how can this identical set of genetic instructions produce different types of cells?
How can a single cell, the fertilized egg, generate so many different cell types?
How can the cells in our body organize themselves i nto functional structures? Rather, they become organized into intricate tissues and organs. During development, cells divide, migrate, and die; tissues fold and separate.

This creation of ordered form is called morphogenesis, and it involves coord inating cell growth, cell m igration, and cell death. If each cell in our face were to undergo just one more cell division, we 'would be considered horribly malformed. If each cell i n our arms underwent just one more round of cell division, we could tie our shoelaces without bending over.
How do our cells know when to stop dividing? How is cell division SO tightly regulated?
The question of reproduction. There are many tra n sien t cell types that are formed during development but are not seen i n the adull.
Some of these embryonic cells are transitional stages or precu rso rs of ad u l t cell types. How are these germ cells set apart from the cells that are constructing the physical structures of the embryo, and what are the i nstructions i n the nucleus and cytoplasm that allow them to form the next generation? Some organisms can regenerate their entire body.
Some salamanders regenerate their eyes and legs, and many reptiles can regenerate their tails.Molecular Regulation of Cell—Cell Interactions The specialized junctions that link cells to their neighbors provide the basis for cell—cell contact and signaling in multicellular tissues. The past few years have witnessed significant progress in this area thanks to multidisciplinary efforts by cell biologists, geneticists, developmental biologists, physicists, and computer scientists.
One of the critical differences between you and a machine is that a machine is never required to function until after it is built. Accrual of at least 60 graduate course credits is needed for the PhD degree. Your password has been changed.
