However, it has been demonstrated that cadherins provide intimate contact between osteoclast precursors and stromal cells, which express crucial growth factors for osteoclast differentiation [ 135].
Eggs with a serosa express crucial bacterial recognition genes, such as PGRP-LA, and many extracellular signaling components, such as serine proteases, at higher levels than serosa-less eggs, indicating constitutive expression in the serosa.
WASHINGTON, March 16 - President Bush expressed crucial support on Wednesday for Representative Tom DeLay, the House majority leader, who is facing growing inquiries here and his home state, Texas, over accusations of illegal fund-raising and improper ties to lobbyists.
Particularly, a large subset of differentially expressed crucial genes was also confirmed by semi-quantitative RT-PCR [Additional file 7: Supplemental Figure S4].
The primary endosymbiotic bacterium (Buchnera aphidicola) engages in obligate symbiosis with A. pisum [ 7– 9], expressing crucial genes for the biosynthesis of essential amino acids (i.e., methionine, cysteine and tryptophan [ 9– 11]); it also plays a role in aphid growth and reproduction [ 5, 12– 12].
This is an important observation; during late pregnancy, Runx2-expressing tissue, although abnormally differentiated, was still able to express factors crucial for normal alveolar development.
I can't express how crucial this is to a service that handles such an important, tedious part of our existence.
Clusters and networks (and networks of clusters and networks) express a crucial relevance for knowledge and innovation.
Increasing evidence has indicated that the timing of oncogene activation, the cell type(s) in which it is activated and the level at which it is expressed are crucial to modelling human leukaemic malignancies (Ren, 2004).
Previous studies suggested that, in skeletal muscle, the four major plectin isoforms expressed are crucial for the integrity of myofibers by specifically targeting and anchoring desmin IF networks to Z-disks (plectin isoform 1d, P1d), costameres (P1f), mitochondria (P1b) and the nuclear/sarcoplasmic reticulum (SR) membrane system (P1).
The freedom to speak and express is thus crucial for the formation of public opinion on political questions, and is indispensable to the discovery and spread of political truth.
