Synthesis of apolipoproteins, alphafoetoprotein, albumin, and transferrin by the human foetal yolk sack and other foetal organs.
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 byExpand

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 wereExpand

[Expression of exogenous porcine transforming growth factor beta-1 gene in ES cells and its effect on their differentiation in vitro].
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 stemExpand

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 humanExpand
