Evidence that fibroblast growth factor 5 is a major muscle-derived survival factor for cultured spinal motoneurons.

We examined the potential role of fibroblast growth factor 5 (FGF-5) as a target-derived trophic factor for spinal motoneurons. Northern analysis of total RNA from rat skeletal muscle revealed an FGF-5 mRNA transcript both during the period of embryonic motoneuron death and in the adult. Recombinant human FGF-5 supported the survival of highly enriched cultures of embryonic chick motoneurons. S...

Fibroblast Growth Factor-1 vs. Fibroblast Growth Factor-2 in Ischemic Skin Flap Survival in a Rat Animal Model

BACKGROUND One of the main challenges in skin flap surgery is tissue ischemia and following necrosis. The present study compares the effects of fibroblast growth factors 1 and 2 on increasing cutaneous vasculature, improving ischemia, and preventing distal necrosis in ischemic skin flaps in rat model. METHODS Thirty rats were allocated into 3 groups (n=10) and 2×8 cm dorsal rando...

Hepatocyte growth factor (HGF/SF) is a muscle-derived survival factor for a subpopulation of embryonic motoneurons.

Muscle-derived factors are known to be important for the survival of developing spinal motoneurons, but the molecules involved have not been characterized. Hepatocyte growth factor/scatter factor (HGF/SF) plays an important role in muscle development and motoneuron axon outgrowth. We show that HGF/SF has potent neurotrophic activity (EC50=2 pM) for a subpopulation (40%) of purified embryonic ra...

Evaluation of Chronotropic Properties of Mouse Embryonic Stem Cells-Derived Cardiomyocytes After Fibroblast Growth Factor Treatment

Purpose: We investigated the effect of (bFGF) (basic-Fibroblast Growth Factor) on the differentiation of divided cardiomyocytes from mouse embryonic stem cells (ES) and their pharmacological properties. Materials and Methods: The mouse embryonic stem cells (Royan B1) were cultured as 800 cells per 20µl of a hanging drop. After two days, ES cells in each drop aggregated to form embryoid bodies ...
