This review covers the preparation, characterization, properties, and applications of
methylcelluloses (MC). In particular, the influence of different chemical modifications of …

Cells in organs and tissues, it is now well established, make permeable junctions that
provide a path for direct flow of molecules between cell interiors. Ever since the nearly …

Antisera prepared against BALB/c Meth A sarcoma in syngeneic or compatible F1 mice
recognize a protein with an apparent molecular weight of 53,000 in extracts of [35S] …

A point mutation in the simian virus 40 large-T gene, which was generated by mixed
oligonucleotide mutagenesis and resulted in the conversion of Lys 128 to Thr, produced a …

The hallmark of differentiated mammary epithelial cells is a copious secretion of milk-specific
components regulated by lactogenic hormones. We describe an established clonal cell line …

Cultured cells derived from either normal or malignant tissues of several species have been
tested by injection into the immune-deficient nude mouse in order to determine the cellular …

Clonal isolates of mouse 3T3 cells and primary rat embryo cells, recovered nonselectively
after infection by simian virus 40 (SV40), have been tested for tumorigenicity in the immune …

Abstract T98 and T98G are two related cell lines that were derived from a human
glioblastoma multiforma tumor. T98G has almost twice as many chromosomes as T98 …

The effect of human epidermal growth factor (hEGF), a 5,400 molecular weight polypeptide
isolated from human urine, on the growth of human foreskin fibroblasts (HF cells) was …

As many as 40 distinct oncogenes of viral and cellular origin have been identified to date.
Many of these genes can be grouped into functional classes on the basis of their effects on …
