limb buds การใช้

• As larvae metamorphose, they develop digits from their limb bud protrusions.
• Propagation phase involves the control of distal progression during limb bud development.
• Sessions demonstrated his theory by implanting tiny plastic beads into tadpole limb buds.
• Shh functions in diverse processes in development, including patterning limb bud tissue differentiation.
• Wing and limb buds can be seen and each abdominal segment is fringed with short spines.
• It did so by preventing the fetuses from developing new blood vessels in those limb buds.
• The "'limb bud "'is a structure formed early in limb development.
• The studies on morphogenesis of limb buds have been focused on one particular axis of limb bud.
• The studies on morphogenesis of limb buds have been focused on one particular axis of limb bud.
• The protein encoded by this gene may play a role in determining positional values in developing limb buds.
• By isolating the Shh gene and implanting it into the anterior limb bud, mirror image digit duplications formed.
• However, some recent evidence using microinjected embryos suggests that the cells are prespecified early in limb bud development.
• Cells from the lateral plate mesoderm and the myotome migrate to the limb field and proliferate to create the limb bud.
• Even more striking, the parasites invariably headed for the hindquarters of the infested tadpoles, forming cysts near the limb buds.
• By damaging the hind-limb buds when the amphibians are sprouting legs, the worm seems to turn frogs into sitting ducks.
• Python embryos even have fully developed hind limb buds, but their later development is stopped by the DNA mutations in the ZRS.
• Limb bud regulation and development of the lungs, liver, teeth and facial mesenchyme cells are other important functions attributed to BMP4 signaling.
• The AER is known to express FGF2, FGF4, FGF8, and FGF9, while the limb bud mesenchyme expresses FGF2 and FGF10.
• Their breeding chambers, inside of which they remain during the early stages of development, are abandoned after the formation of limb buds.
• The position of the limb bud, and hence the AER, is specified by the expression boundaries of Hox genes in the embryonic trunk.
