Although the SDF1/CXCR pathway and its functions were originally identified in the immune system, emerging data suggest that this pathway plays important roles in various functions like proliferation and migration of tissues during morphogenesis [33] [38].
Chemotaxis of CXCR4-expressing murine muscle satellite cells towards SDF-1 has also been demonstrated, suggesting that migration of tissue-specific stem cells may be regulated by SDF-1 (Ratajczak et al, 2003).
It is, however, not clear whether this is due to an enhanced cDC migration from the periphery, the differentiation of DCs in situ, or decreased migration of tissue-resident DCs towards DLNs upon allergen encounter [ 36].
The fluorescent structures therefore appear out of context of the sample's anatomy and features such as the growth or migration of fluorescent tissue through the surrounding tissue may therefore be hard to interpret.
These genes are associated with such processes as the development and migration of endothelial tissue, the migration of smooth muscle cells, hematopoiesis, and vasculogenesis.
This is consistent with the considerable trafficking of mucosal DC into lymph, which occurs in resting animals 50, and with the evidence that constitutive migration of resting tissue DC to LN is a central component of self-tolerance 57.
Additionally, our analysis shows that siRNA-induced osteopontin inhibition results in reduced clonogenic survival and migration of soft tissue sarcoma and breast cancer cell lines (Hahnel et al., manuscript submitted).
These hybrid scaffolds exhibited excellent biomechanical properties with fiber and pore sizes that allowed attachment and migration of adipose tissue-derived stem cells.
The relative position of the inferior and superior glands, which are named according to their final location, changes because of the migration of embryological tissues.
