The formation of viable teratocarcinoma-adult chimaeras, by aggregation rather than by microinjection, is described. Aggregation chimaeras were produced using two pluripotential EC cell lines, PSA-1/NG-2 and PSA-4/TG12. The frequency and distribution of chimaerism were assessed, for the EC cells, in conceptuses recovered from in utero and in adults. In utero 37% of the morphologically normal conceptuses formed from PSA-l/NG-2 aggregations and 73% of the morphologically normal conceptuses produced from PSA-4/TG12 aggregations were found to be chimaeric. However, the frequency of chimaeric adults formed from both cell lines was lower. The reason for this discrepancy appeared to be that in the chimaeric conceptuses, the predominant tissues colonized by the EC cells were the extraembryonic membranes.

Although the outlines of human adenovirus entry and uncoating in HeLa cells has been clarified in recent electron microscope studies, several details remain unclear or controversial. Furthermore, morphological features of early interactions of human adenovirus with non-permissive mouse cells have not been extensively documented. In the course of studies on the effects of human adenoviruses type 5 (AD-5) and type 12 on cultured preimplantation mouse embryos we have examined virus attachment, entry and uncoating. Here we present the ultrastructural findings for AD-5.AD-5 was grown in HeLa cells and purified by successive velocity gradient and equilibrium density gradient centrifugations in CsCl. After dialysis against PBS, virus was sedimented and resuspended in embryo culture medium. Embryos were placed in culture at the 2-cell stage in Brinster's medium.

Normal Feature

The stage specific appearance of a retravirus, termed the Intracisternal A particle (IAP) is a normal feature of early preimplantation development. To date, all feral and laboratory strains of Mus musculus and even Asian species such as Mus cervicolor and Mus pahari express the particles during the 2-8 cell stages. IAP form by budding into the endoplasmic reticulum and appear singly or as groups of donut-shaped particles within the cisternae (fig. 1). IAP are also produced in large numbers in several neoplastic cells such as certain plasmacytomas and rhabdomyosarcomas. The role of IAP, either in normal development or in neoplastic behavior, is unknown.
