摘要: Summary Introduction Primordial germ cells (PGCs) have been studied since the 19th century with several different methods. The earliest works were based on morphological criteria of these associated or not a particular staining. Different markers proposed in immunohistochemistry among which we can quote Stage-specific embryonic antigene-1 (SSEA-1), mouse antigen-1 (EMA-1) heat shock protein 90. Unfortunately, none them are germline specific. VASA is considered as one most reliable marker for PGCs by some authors its expression being to limited cells. However, other studies reported somatic Here, described protein, HSP90, and early chick embryo. Material methods Embryos from stages Hamburger-Hamilton (HH) 19, 21 28 collected. dissected fixed Serra's medium. Sections placed slides PAS staining double HSP90 VASA. Results observed but well cell lineages spatio-temporal gradient respect characteristics development each organ. conclusion that line
