POLY(LACTIC-GLYCOLIC)ACID CROSS LINKED ALENDRONATE (PLGA-ALN) A SHORT TERM CONTROLLED RELEASE SYSTEM FOR STEM CELL DIFFERENTIATION AND DRUG DELIVERY

摘要

The present invention relates to a bisphosphonates and synthetic polymeric carriers to form a sustained release system. The present invention also provides a method for preparing a sustained release system, comprising activation of the synthetic polymeric carriers and the cross linking reaction. The present invention further provides methods for enhancing stem cell differentiation into osteogenic lineage and chondrogenic lineage, which comprise culturing a population of stem cells in specific micro-environments.
