Genetic studies of mrp, a locus essential for cellular aggregation and sporulation of Myxococcus xanthus.
Under starvation conditions, Myxococcus xanthus undergoes a complex developmental process which includes cellular aggregation and sporulation. A transposon insertion mutant (the Tn5-Omega280 mutant)… Expand
Analyses of mrp genes during Myxococcus xanthus development.
Myxococcus xanthus is a gram-negative soil bacterium that undergoes development under starvation conditions. Our previous study identified a new genetic locus, mrp, which is required for both… Expand

Fragments of human foetal organs and blood at 5-11 weeks of postfertilization development were cultured in radioactive protein precursors. The secreted products were characterized by… Expand
Apolipoprotein expression by murine visceral yolk sac endoderm.
Apolipoprotein expression was examined in the postimplantation mouse embryo. Antibodies directed against murine Apolipoprotein AI and human low-density lipoprotein (LDL) particles specifically… Expand
Developmentally regulated expression of insulin-like growth factors by differentiated murine teratocarcinomas and extraembryonic mesoderm.
The expression of plasma membrane receptors for insulin-like growth factors (IGFs) by PC13 embryonal carcinoma (EC) cells, and their immediate differentiated progeny PC13END was examined by binding… Expand

Filamentous bacterial cells often provide biological information that is not readily evident in normal-size cells. In this study, the effect of cellular filamentation on gliding motility of… Expand
Cloned human teratoma cells differentiate into neuron-like cells and other cell types in retinoic acid.
Single cell clones were isolated from the human teratoma line, Tera-2. The cells of three of these clones were studied. The progressively growing cells were shown to be tumorigenic, and they were… Expand

A TGF-beta 1 gene expression plasmid was constructed by inserting the porcine 1.7 Kb TGF-beta 1 cDNA into BamHI site of retrovirus vector Dol. The plasmid DNA was introduced into mouse embryonic stem… Expand
Use of readback signal modulation to measure head/disk spacing variations in magnetic disk files
-A new method is developed for measuring the dynamics of the head/disk interface in magnetic disk files. This method utilizes the modulation of a sinusoidal readback signal that results from head/… Expand
[Biological characterization of a monoclonal antibody TB 21 against human transforming growth factor-beta 1].
A hybridoma TB 21 clone was derived from fusion between Sp 2/0-Ag 14 myeloma cells and spleen cells of BALB/c mice immunized with transforming growth factor-beta 1 (TGF-beta 1) purified from human… Expand
