Adult stem cells have potential use for several biomedical applications, including cell replacement therapy, gene therapy, and tissue engineering. However, such applications have been limited due to difficulties encountered in expanding functional adult stem cells. We have developed a new approach to the problem of adult stem cell expansion based on the(More)
6 new PGD alleles are described. 2 of these (PGD Wantoat and PGD Canberra) control proteins that are electrophoretically slow: the other 4 control fast variants. The heterozygotes PGD A/PGD Wantoat and PGD A/PGD Canberra give similar band spacing after starch gel electrophoresis, but the relative intensities of the bands in the 2 patterns is different. Of(More)
We investigated the ability of a new type of biological material, the self-assembling peptide scaffold, to foster tissue-like function by a putative adult rat hepatocyte progenitor cell line, Lig-8. In conventional adherent petri-dish cultures, Lig-8 cells divide exponentially, express markers for definitive endoderm HNF3 beta and hepatocyte lineage,(More)
Hyperreactive malarious splenomegaly (HMS), formerly known as tropical splenomegaly syndrome (TSS), was recognized some 20 years ago as an entity distinct from the splenic enlargement resulting directly from malarial parasitaemia. Its basis appears to be a disturbance in the T-lymphocyte control of the humoral response to recurrent malaria, possibly linked(More)
Levels of species and class-specific malarial antibody were studied in 249 New Guineans with tropical splenomegaly syndrome (TSS) and in 87 control subjects living in the same area. Titres of IgG and IgM antibody to Plasmodium falciparum, P. vivax and P. malariae were estimated by indirect immunofluorescence. Both Ig and IgM antibody levels were higher in(More)
Ovalocytosis, an hereditary condition in which most erythrocytes are oval in shape, is a polymorphism that occurs in up to 20% or more of the population in Papua New Guinea and Malaysia. Due to the geographical correlation of the trait with endemic malaria, the possibility of a selective advantage in resistance to malaria has been raised. In a study of 202(More)
Two hundred and twenty-six patients were diagnosed with myelodysplastic syndrome (MDS), according to the French-American-British (FAB) criteria, over a 13-year period, and studied retrospectively in a single institution in order to study indicators which were prognostically significant. Analysis of clinical and laboratory data indicated that the FAB(More)
The HLA profile of three New Guinean populations, two Highland (Asaro, Watut), and one Coastal is presented. The Highland populations are characterized by a low average number of alleles segregating at the HLA loci and also by a low mean value of heterozygosity at these loci. The genetic affinities of the two Highland groups with other Melanesian(More)
