Location of a cell may be critical in the determination of its ultimate fate during development, as in the development of vertebrate limbs. This fact arises from… injecting the anterior region of the egg with cytoplasm from the posterior region of another wild-type egg.

5.Location of a cell may be critical in the determination of its ultimate fate during development, as in the development of vertebrate limbs. this fact arises from

The set of cytoplasmic determinants a particular cell receives helps determine its developmental fate by regulating expression of the cell’s genes during the course of cell differentiation. The other important source of developmental information is the environment around the cell, especially signals impinging on an embryonic cell from other nearby embryonic cells.

6.Location of a cell may be critical in the determination of its ultimate fate during development, as in the development of vertebrate limbs. this fact arises from

location of a cell may be critical in the determination of its ultimate fate during development, as in the development of vertebrate limbs. this fact arises from. a gradient in the concentration of the morphogen, sonic hedgehog. cloning dolly, a dorset sheep, showed.

7.Location of a cell may be critical in the determination of its ultimate fate during development, as in the development of vertebrate limbs. this fact arises from

The point during development at which a cell becomes committed to a particular fate is called determination. Differentiation (specialization) is the end product of determination. Determination happens when certain genes are activated or inactivated, and differentiation completes when the cell synthesizes all of the tissue-specific proteins that the activated genes encode.

8.Location of a cell may be critical in the determination of its ultimate fate during development, as in the development of vertebrate limbs. this fact arises from

The fetal skeleton arises from neural crest and from mesoderm. Here, we provide evidence that each lineage contributes a unique stem cell population to the regeneration of injured adult bones. Using Wnt1Cre::Z/EG mice we found that the neural crest-derived mandible heals with neural crest-derived skeletal stem cells, whereas the mesoderm-derived tibia heals with mesoderm-derived stem cells.

9.Location of a cell may be critical in the determination of its ultimate fate during development, as in the development of vertebrate limbs. this fact arises from

In vertebrate embryos, the jaw, hyoid and gill arch skeleton (or, in amniotes, their derivatives, the jaw, auditory ossicles and laryngeal skeleton) arises from a series of transient, bilaterally paired pharyngeal arches that form on the sides of the embryonic head (Gillis et al., 2012a; Graham et al., 2019), while the paired fins or limbs of jawed vertebrates arise as buds that project from …

10.Location of a cell may be critical in the determination of its ultimate fate during development, as in the development of vertebrate limbs. this fact arises from

It has been proposed that these hormones may modulate patterning during development (Krueckl et al., 2002). Expression of myogenic bHlH (basic helix-loop-helix) genes is induced by signaling proteins of the Wnt family, originating in the dorsal regions of the neural tube, and Sonic hedgehog (Shh), secreted from both the neural tube floor plate and the notochord ( Fan and Tessier-Lavigne, 1994 …
