Polyurethanes (PUs) are able to degrade into harmless molecules upon implantation and have received a significant level of attention as a biomaterial. PUs based on polycaprolactone (PCL) and amino acid derivatives are examples of these polymers. As a potential biomaterial, their biocompatibility coupled with biodegradability attracted attention in tissue engineering applications. In this study, a...
Tumstatin anti-tumor peptide of 19peptide can inhibit the proliferation of melanoma tumor cell. To study its effect on the proliferation and apoptosis of different cells and verify its no anti-tumor specificity, the base sequence of 19peptide was designed and constructed engineering bacteria. The soluble 19peptide was obtained from one step chitin affinity chromatograph. By such experiment as MTT...
In this experiment, the bone marrow stroma cells (BMSCs) were harvested and then cultured in "neural stem cells (NSCs) medium" which was modulated by our lab with R R. of China patent number as ZL 02134314.4 in vitro. The proliferation of NSCs was confirmed by formation of cell's clones and scan electron microscopy test. The identifications of NSCs, neurons-like cells and glial-like cells...
