Preparing model organisms for experimental analysis involves intentionally misrepresenting mechanisms or phenomena, such as the standardized staging of ontogeny that misrepresents the degree and kinds of variation present in development (Love 2010a; Section 5.2).
This chapter focuses on discussing the building blocks necessary to mimic the vascular microenvironment including the promise of stem cell technology as a cellular source, as well as chemical and mechanical cues present in development and adult physiology.
Since we have not included foetal tissue in this study, it is possible that higher levels are present in development.
This is well presented in development of the whorled structure of single floral meristems, but by extension, the same general radial gradient mechanisms might operate at the inflorescence level, as suggested by previous work on sunflower and Microseris.
Second, Shh, a key factor in limb development, exhibits a unique second phase of signaling late in development of the bat wing that is not present in the development mouse autopodia [ 9].
In most software development organizations, security concerns are not present in the development process.
"My clients are now asking me to be present in the development process with the brands," he said.
But this problem is already present in the development of any software.
Two larval stages are present in typical development of hermaphroditic generation: cercaria and metacercaria.
In fact, these molecules are known to be present in follicle development in the fetal ovary [ 39] and adult ovarian follicle [ 40, 41].
