title: [Expression of human annexin V in different fetal tissues].
abstract: OBJECTIVE
  To investigate the expression of human annexin-V (HA-V) in relation to HBV infection in different fetal tissues.
  
  
  METHODS
  Immunohistochemistry was employed to detect the expression and distribution of HA-V in the liver, kidney, ovary, heart, fallopian tube, spleen, and thymus gland of human fetus.
  
  
  RESULTS
  HA-V expression was detected in different tissues including the ovary, liver, intrahepatic bile duct, heart, kidney, lymphocytic cells in the thymus gland, epithelial cells of the fallopian, and cortical and medullary cells of the spleen. HA-V was distributed mainly in the cytoplasm of the cells. The liver tissues exhibited greater gray scale for HA-V expression than in the other tissues (P<0.05) and no significant difference was observed in the other tissues than the liver (P>0.05) in image analysis with Photoshop 7.0.
  
  
  CONCLUSIONS
  HA-V is an inherent protein in fetal tissues with possible relation to HBV infection of different tissues as a HBV receptor. Greater amount of HA-V in the liver may account for the vulnerability of the liver to HBV infection.
