Two monoclonal antibodies (mAbs) against bovine heparin-binding growth factor II (HBGF-II)/basic fibroblast growth factor (bFGF) were obtained from mouse hybridoma cell lines. They were highly specific for bFGF from bovine, human, and mouse sources and did not cross-react with bovine heparin-binding growth factor I (HBGF-I)/acidic fibroblast growth factor(More)
EGF precursor (proEGF) is a member of the family of membrane-anchored EGF-like growth factors that bind with high affinity to the epidermal growth factor receptor (EGFR). In contrast to human transforming growth factor-alpha precursor (proTGFalpha), which is sorted basolaterally in Madin-Darby canine kidney (MDCK) cells (Dempsey, P., and R. Coffey, 1994. J.(More)
Immunohistochemical localization of basic fibroblast growth factor (bFGF) was studied in the rat pituitary gland at light and electron microscopic levels using a specific monoclonal antibody. In the anterior lobe, bFGF-immunoreactivity was found mostly in a cell population without secretory granules, which was identified as the folliculo-stellate (FS) cell(More)
During endochondral bone formation, cartilage cells show increased matrix synthesis and rapid proliferation. We found that cartilage matrix contains at least two types of heparin binding growth-promoting components. One, with a higher affinity to heparin, was identified as chondromodulin I (Hiraki, Y., Tanaka, H., Inoue, H. , Kondo, J., Kamizono, A., and(More)
Somatomedin/insulin-like growth factor (IGF)-like polypeptides (designated SMP) were purified from the serum-free conditioned medium of cultured rat epithelial-like cells, 18,54-SF. A monoclonal antibody (MAb) was produced against partially purified SMP. The antibody was immunoglobulin G1 relatively specific for multiplication-stimulating activity III-2(More)
BACKGROUND The turning point in the deterioration of physical function seems to occur between the ages of 70 and 80 years. In particular, muscle strength may decline even more in subjects older than 75. A recent study found that the angiotensin-converting enzyme (ACE) genotype also affects physiological left ventricular hypertrophy. A very limited number of(More)
Human bladder carcinoma cell line EJ-1 secreted a protein of 30 kDa as a major component. This protein was purified from the serum-free conditioned medium of EJ-1. Its N-terminal amino acid sequence was identical to that of fibroblast-derived endothelial cell growth factor (f-ECGF), but there were differences in their amino acid compositions and isoelectric(More)
The distributions of acidic fibroblast growth factor (aFGF) and basic FGF (bFGF) in extracts of various cultured mammalian cells were determined from their elution profiles on heparin-affinity chromatography, and assay of activity as ability to stimulate DNA synthesis in BALB/c3T3 cells. Only aFGF was found in extracts of mouse melanoma B 16 cell and rat(More)
The potential usefulness of a zwitterionic detergent, 3-[(3-cholamidopropyl)dimethylammonio]-1-propane sulfonate (CHAPS), in the stabilization of acidic and basic fibroblast growth factors (FGFs) was examined. Among several detergents, CHAPS was found to be not only non-cytotoxic but also most useful in handing the diluted preparations of FGFs. The(More)
BACKGROUND Little is known about the association between physical fitness and cognitive function in very elderly people (over 80 years of age). OBJECTIVES To evaluate that relationship in 85-year-old community-dwelling individuals. METHODS Out of 207 participants (90 males, 117 females) who were 85 years old and community-dwelling, 205 completed the(More)
