Surface topography of primordial germ cells (PCCs) in early chick embryos were investigated by scanning electron microscopy. PGCs were large and spherical cells, possessing many microvilli and blebs on their surfaces. The microvilli measured about 100 nm in diameter and 150 to 600 nm in length, occasionally up to 2 μm. They were seen in all stages examined, and were variable in number. It seems that such alteration in number is due to the cell cycle. Blebs, which were another characteristic on the surface of the PGC, measured 0.7 to 1 μm in diameter. They are infra-cytoplasmic yolk granules and lipid droplets. These blebs of the PGCs seem to be diminished upon arrival at the presumptive gonads. [ABSTRACT FROM PUBLISHER] |
