Crystal Structure of Stem Cell factor: Implication In Stem Cell Factor Receptor Dimerization and Activation

Production and functional characterization of human insulin-like growth factor 1

Insulin-like growth factor 1 (IGF-1) is a polypeptide hormone produced mainly by the liver in response to the endocrine growth hormone (GH) stimulus. This protein is involved in a wide range of cellular functions, including cellular differentiation, transformation, apoptosis suppression, migration and cell-cycle progression and other metabolic processes. In the current study, human heart cDNA w...

Effects of Inflammatory Cytokine Tumor Necrosis Factor-α on Human Mesenchymal Stem Cell Gene Expression: A Mechanism for Liver Regeneration

Introduction  Insulin-like growth factor I (IGF-I) which is produced in abundance in the normal adult liver, is deeply involved in hepatocyte survival, growth, and differentiation during liver development. IGF-I plays the roles via the receptor (IGF-IR) signaling pathway. IGF-IR unlike IGF-I is expressed strongly in the developing liver, but much more weakly in adults. Objective:  We hypothesi...

P-126: Stem Cell Factor Increases Blastocyst Formation in Mouse Two-Cell Embryo Culture

Background: It is demonstrated that c-Kit( receptor of stem cell factor) mRNA is expressed in late 2-cell stage to the expanded and hatched blastocyst and the stem cell factor (SCF) transcript is detected in the oviduct and uterus. The aim of this study was to investigate the effect of different doses of SCF on mouse 2-cell embryo development in vitro. Materials and Methods: 4-6 weeks old femal...

Preparation and characterization of Sr-Ti-hardystonite (Sr-Ti-HT) nanocomposite for bone repair application

Objective(s): Hardystonite (HT) is Zn-modified silicate bioceramics with promising results for bone tissue regeneration. However, HT possesses no obvious apatite formation. Thus, in this study we incorporated Sr and Ti into HT to prepare Sr-Ti-hardystonite (Sr-Ti-HT) nanocomposite and evaluated its in vitro bioactivity with the purpose of developing a more bioactive bone substitute material. Ma...
