We have used fluorescein isosthiocyanate-conjugated gelatin (FITC-gelatin) (1 mg/ml) to localize cell surface fibronectin in unfixed live cells in cultures. FITC-gelatin stains the fibronectin matrix on primary cultures of rat and chick embryo fibroblasts as well as untransformed, established cell lines. In live cultured cells, fibronectin in many areas of the extracellular matrix is inaccessib...
The extraction of catfish (Clarias gariepinus) bone gelatin was optimized by using Response Surface Methodology (RSM) involving 4-factors, 5-levels Central Composite Design (CCD). The optimum conditions for extraction were produced by a pre-treatment of 3.35% HCl for 14.5 h along with hot water extraction at 67.23°C for 5.2 h. Results showed that the predicted yield by RSM (61.81%) was closely ...
Background: In order to evaluate bone induction and repair in cranial bone defects by the use of combination of Octacalcium Phosphate/Bone Matrix Gelatin (OCP/BMG), this study was conducted. Materials and Methods: We used 40 young male Sprague dawley rats (5-6 weeks age). A full thickness standardized trephine defect, 5mm in diameter, was made in the rat parietal bone and OCP combined with BMG ...
background gelatin and chitosan are known as biodegradable and biocompatible biopolymers.these biopolymers have recently receivedincreasingly more attention for tissueengineering.the aim of this study was to evaluate the toxicity effects of gelatin-chitosan film on bone marrow stromal cell(bmscs) culture in rat. material & methods: first, gelatin...
Background: Stem cell therapy has been developed as an effective treatment method for the heart failure. Also, extracellular matrix has shown the positive effects in stem cell differentiation and myocardial tissue organization. Cardiogel is a native cardiac extracellular matrix (ECM) derived from cardiac fibroblasts. In the present study the role of cardiogel is examin...
During invasion and metastasis, cancer cells interact closely with the extracellular matrix molecules by attachment, degradation, and migration. We demonstrated previously the local degradation of fluorescently labeled gelatin matrix by cancer cells at invasive membrane protrusions, called invadopodia. Using the newly developed quantitative fluorescence-activated cell sorting-phagocytosis assay...
The present study evaluated the hemostatic efficacy and handling of gelatin-thrombin matrix hemostatic sealant during intracranial procedures. A retrospective analysis of 478 consecutive patients undergoing intracranial procedures identified seven patients with acute intense or persistent intraoperative bleeding which could not be arrested in time by standard hemostatic methods. The efficacy of...
STUDY DESIGN A randomized, controlled animal study. PURPOSE To investigate the effectiveness of fusion and new bone formation induced by demineralized bone matrix (DBM) strips with jelly strengths. OVERVIEW OF LITERATURE The form of the DBM can make a difference to the outcome. The effect of different jelly strengths on the ability of DBM to form new bone is not known. METHODS Forty-eight...
BACKGROUND AND PURPOSE Absorbable gelatin-thrombin matrix is increasingly being used in neurosurgical procedures; unlike other hemostats, the stable matrix is left undisturbed and fills the surgical bed after achieving hemostasis. We investigated the immediate postoperative radiographic imaging appearance of the gelatin-thrombin matrix in intracranial operative beds. MATERIALS AND METHODS Thi...
