The transplanta- tion of the presumptive limb (limb field) is illustrated, together with its com- plete self-differentiation in the flank region. The approximate location of the presumptive ear, olfactory organ, and heart are shown in the neurula. When transplanted to another embryo these regions give rise to the structures shown in Figure 45.

The transplanta- tion of the presumptive limb (limb field) is illustrated, together with its com- plete self-differentiation in the flank region. The approximate location of the presumptive ear, olfactory organ, and heart are shown in the neurula. When transplanted to another embryo these regions give rise to the structures shown in Figure 45. The various presumptive structures are called fields at the neurula stage, and the nature of these fields is discussed in Chapter 8. The time at which presumptive structures will self-differentiate when transplanted varies from one structure to another. In general, mesodermal structures such as the limb will self-differentiate earlier than ectodermal structures such as the eye, ear, and Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Barth, Lester G.
