Journal ArticleDOI
A common precursor for hematopoietic and endothelial cells
TL;DR: Findings provide strong evidence that the blast colony-forming cell represents the long-hypothesized hemangioblast, the common precursor of the hematopoietic and endothelial lineages.
Journal ArticleDOI
Isolation of human mdr DNA sequences amplified in multidrug-resistant KB carcinoma cells.

TL;DR: Evidence is presented that multidrug-resistant sublines of human KB carcinoma cells, selected for resistance to either colchicine, vinblastine, or Adriamycin (doxorubicin), display amplification of two different DNA sequences homologous to the hamster mdr gene, suggesting that the mdr1 gene is involved inMultidrug resistance in human cells.
Journal ArticleDOI
Silver nanoparticles induce cytotoxicity by a Trojan-horse type mechanism.
TL;DR: It seemed that AgNPs were ionized in the cells to cause cytotoxicity by a Trojan-horse type mechanism suggested by previously reported studies.
Journal ArticleDOI
A common precursor for primitive erythropoiesis and definitive haematopoiesis.
Marion Kennedy,Marion Kennedy,Meri T. Firpo,Meri T. Firpo,Meri T. Firpo,Kyunghee Choi,Kyunghee Choi,Kyunghee Choi,Charles Wall,Charles Wall,Scott M. Robertson,Scott M. Robertson,Neil Kabrun,Neil Kabrun,Gordon Keller,Gordon Keller +15 more
TL;DR: Kinetic analysis demonstrated that the blast colony-forming cells represent a transient population, preceding the establishment of the primitive erythroid and other lineage-restricted precursors, which may represent the earliest stage of embryonic haematopoietic commitment.
Journal ArticleDOI
Repeated-dose toxicity and inflammatory responses in mice by oral administration of silver nanoparticles.
Eun-Jung Park,Eunjoo Bae,Jongheop Yi,Younghun Kim,Kyunghee Choi,Sang Hee Lee,Junheon Yoon,Byung Chun Lee,Kwangsik Park +8 more
TL;DR: It is suggested that repeated oral administration of nano-sized AgNPs may cause organ toxicity and inflammatory responses in mice.
