Tissue specificity：Lymphocytes, macrophages, neutrophils, microglial cells and astrocytes. Found in spleen, thymus, bone marrow, lymph nodes and, at lower levels in brain, small intestine, stomach and kidney. CXCR4-A is predominant in all tissues tested. During embryonic development, high levels are detected in the endothelium of developing blood vessels and in many regions of the developing brain including the olfactory epithelium, olfactory bulb, hippocampus, cerebellum and spinal cord. {ECO:0000269|PubMed:9634237, ECO:0000269|PubMed:9634238}.
Induction：
Developmental stage：High expression during embryonic development does not seem to be associated with the differentiation of any particular cell type, but is widely utilized when there is a requirement for cell movement. Frequently associated with less differentiated cell types and down-regulated with subsequent differentiation. Detected in sites with hemopoietic potential: the yolk sac (7.5, 8.5 and 12.5 dpc) and fetal liver (12.5 dpc). During gastrulation, at 7.2 to 7.8 dpc, expressed in the mesoderm and the definitive endoderm. As gastrulation pattern fades (8.5 dpc), expression in the mesoderm is down-regulated, while it becomes predominant in neural ectoderm. Endodermal expression is retained in the foregut and later in a subset of foregut derivatives, including the stomach (10.5 dpc), the cystic ducts of the gall bladder and the lung epithelium (12.5 dpc). In neuronal tissue: at 10.5 and 12.5 dpc, expressed in the dorsal root ganglia, in the ventral mantle layer of the spinal cord (or basal plates), in the hindbrain. At 14.5 dpc, expression more tightly confined to the neural epithelium lining the ventricular space and to the external granular layer of the ventral rhombic lip (the developing cerebellum). Expressed in the outpocketing of the diencephalic floor at 10.5 dpc and in the developing thalamus and, to a lesser extent, the developing hypothalamus. At 14.5 dpc, restricted to the region where thalamus and hypothalamus meet. Detected in a discrete band of cells at the edge of the olfactory bulb. In the vascular system: expressed in the endothelium of numerous blood vessels, but not all, at 10.5, 11.5 and 12.5 dpc, such as vitelline/umbilical vessels, cardiac ventricular wall capillaries, facial vessels and, at 14.5 dpc, in the vasculature of the herniated gut. Expression seems to be associated with expanding vascular networks. In the heart development, expressed at 10.5 dpc in the precursor to the aortopulmonary (AP) septum. At 12.5 dpc, detected in the AP septum at the base of the outflow tract and in the atrioventricular valves. Detected in cranofacial ectoderm from 10.5 to 14.5 dpc. At 10.5 and 11.5 dpc, expressed in the Rathke pouch. {ECO:0000269|PubMed:10479460}.
