How the zebrafish got its stripes
H ow the zebra got its stripes is a frequent topic in popular literature about the natural world. For developmental biologists, however, it is much easier to study the biology of pattern formation in zebrafish, where the tools of experimental embryology and genetics have proved to be very useful. Now, in eLife, David Parichy from the University of Washington and coworkers – including Dae Seok E...
متن کاملHow the mouse got its stripes.
A central issue in developmental biology is the understanding of how various processes interact to produce spatio-temporal patterns in the embryo. To even observe these dynamical patterns directly is a challenge and, although technological advances in, for example, imaging techniques are beginning to address this problem, it is still far from trivial. A new strain of mouse that is deficient in ...
متن کاملHow the zebrafish gets its stripes.
The study of vertebrate pigment patterns is a classic and enduring field of developmental biology. Knowledge of pigment pattern development comes from a variety of systems, including avians, mouse, and more recently, the zebrafish (Danio rerio). Recent analyses of the mechanisms underlying the development of the neural crest-derived pigment cell type common to all vertebrates, the melanocyte, h...
متن کاملHow the snake lost its legs
mystery of how the snake lost its legs might make a good 'Just so' story but it's also a tantalizing developmental question. Snakes have hundreds of similar vertebrae, as shown by the stained skeleton of a python embryo, Antaresia maculosa, (24 days after egg-laying) at top left. Snakes have no forelimbs but pythons have a pair of hindlimb rudiments (removed in picture at top right) at the junc...
متن کاملTiger stripes.
On occasion a high amplitude band-like signal is noted on Doppler spectral recordings of valvular regurgitation (Fig. 1). However, clinically these “tiger stripes” are most often noted with porcine mitral prosthetic valves (Fig. 2), and may be indicative of an acute flail prosthetic leaflet.1–5 These band-like signals appear to be associated with an intracardiac oscillating structure,6 with the...
