lecture 13 Flashcards
what is essential for when tissue needs to change its shape
connections between adjacent epithelial cells
what is the challenge in developmental biology
how does the material exert forces on itself to change its shape
basically what is tissue morphogenesis
during development, embryonic tissue changes its own shape to begin to form the structure required in a functioning adult organism
what happens to generate changes in shape
cell proliferation is happening, but also cells are exerting forces on each other through cell-cell junctions to cause morphogenetic changes
essentially what is tissue shaping
how cell-cell junctions are formed and regulated, how they generate forces necessary so the material itself can change its own shape during development
big concept in dev. bio
how the cells generate the forces and exert those forces to form things like neural tubes
what do we need to know in order to understand tissue shaping
how epithelial cells connect to each other
