  • Title: Attraction of primordial germ cells by notochord in seven somites chick embryo.
    Author: Cuevas P, Aballe M.
    Journal: Experientia; 1978 Nov 15; 34(11):1506-7. PubMed ID: 720489.
    Abstract:
    Chemical studies in chick embryo have indicated the existence of proteoglycan in notochordal sheath. Primordial germ cells were observed with scanning electron microscope on the notochord dorsal face, surrounded with perichordal material. We postulate the identification of such a material with proteoglycan which could attract primordial germ cells to the notochord.
