IGF-II expression is absent in human fetal sympathetic ganglia. (A) Immunohistochemical staining of TH and in situ hybridization of IGF-II and GAP43 (bright field and dark field) in human fetus at week 12. Arrowheads indicate sympathetic ganglia; arrows indicate paraganglia. *Area of magnification. Scale bars represent 200 µm. (B) IGF-II, SCG10, and GAP43 in situ hybridization (bright field and dark field) and TH immunostaining in a 12-week-old fetal adrenal gland. Arrowheads indicate sympathetic ganglia. Scale bars represent 100 µm.
