A boundary model for pattern formation in vertebrate limbs.
We postulate that positional information for secondary embryonic fields is generated by a cooperative interaction between two pairs of differently determined cell types. Positional information is thus generated at the boundaries between cells of different determination. The latter are assumed to result from the primary pattern formation in the embryo. The application of this model to vertebrate...
متن کاملPattern discontinuity, polarity and directional intercalation in axolotl limbs.
Axolotl limb stumps with dorsal-ventral confrontations between digits 2 and 3 but with a normal anterior-posterior pattern were created by grafting between contralateral limbs. Graft and host differed in ploidy to permit a determination of the origin of cells in the regenerated limb. After regeneration, limbs were analysed for skeletal and muscle patterns and for the distribution of marked cell...
متن کاملCellular functions of the Rap1 GTP-binding protein: a pattern emerges.
Rap1 belongs to the Ras subgroup of small GTP-binding proteins. Whereas its early history has focused on its biochemical homology to Ras and the alleged functional antagonism between these two small GTPases, recent cellular evidence suggests that endogenous Rap1 plays a unique, Ras-independent role in eukaryotic cells. Activated by virtually all receptor types and second messengers, Rap1 contro...
متن کاملMetal Abundances of Subdwarf B Stars from SPY – a Pattern Emerges
The formation of sdBs is still puzzling, as is the chemical composition of their atmospheres. While helium and other light elements are depleted relative to solar values, heavy elements are highly enriched. Diffusion processes in the hot, radiative atmosphere of these stars are the most likely explanation. Although several attempts were made, it was not yet possible to model all the observed fe...
متن کاملThe Ribosome Emerges from a Black Box
Although the basic facts about the ribosome were already known 40 years ago, elucidating its atomic structure and molecular mechanisms required sheer persistence and the innovative use of new technology and methods. These advances have transformed our understanding of translation in the cell.
