WebAge-related macular degeneration (AMD) is a blinding disease for which most of the patients remain untreatable. Since the disease affects the macula at the center of the retina, a structure specific to the primate lineage, rodent models to study the pathophysiology of AMD and to develop therapies are very limited. Consequently, our understanding relies mostly … Web7 de abr. de 2024 · Nature has offered a large amount of inspiration for soft robotics strategies. [9, 10] As an example, although biological tissues appear more fragile than the materials in man-made devices, appropriate applications of these soft biomaterials can enable the body to absorb external resistance with high flexibility for improved motion …
On the spontaneous emergence of cell polarity - Europe PMC …
Web15 de jul. de 2014 · Cell polarization, in which intracellular substances are asymmetrically distributed, enables cells to carry out specialized functions. While cell polarity is often induced by intracellular or extracellular spatial cues, spontaneous polarization (the so-called symmetry breaking) may also occur in the absence of spatial cues. WebThis work identifies an intrinsic stochastic mechanism through which positive feedback alone is sufficient to account for the spontaneous establishment of a single site of polarity, … dyrus wife
