WebApr 5, 2024 · In principle, SHH gradients could form through diffusion of ligands in the liquid medium or through lateral movement of ligands within the cell layer (as by diffusion in extracellular matrix, or transport along filopodia) (13–16). To distinguish between these two possibilities, we analyzed gradient formation on a laboratory rocker, which ... WebIn developmental biology, an important problem is understanding the mechanisms underlying the formation of morphogen concentration gradients. The most commonly hypothesized mechanism involves the diffusion and degradation of morphogens from a localized source. Recently, however, an alternative mechanism has been proposed, …
