PEG and Tissue Engineering Solutions

PEG-containing polymers play an important role as biomaterials in diverse applications ranging from drug delivery to tissue engineering. These novel biodegradable materials offer great possibilities for modifying the bulk properties of biomaterials by improving biocompatibility and solubility. With years of practical PEG synthesis and research experience, BOC Sciences has introduced specific skills and expertise for producing high quality PEG. We provide world-class PEG & tissue engineering solutions at competitive prices.

PEG & PEG Gel & Tissue Engineering

PEG is a synthetic non-biodegradable polymer widely used as an artificial scaffold in tissue engineering research. PEG chains of any length can be readily synthesized by controlled polymerization of ethylene oxide or ethylene glycol in aqueous solution. Therefore, PEG is highly biocompatible and very suitable for hydrogels for biological research. PEG hydrogels have the advantage of hydrated structure, generally with high cytocompatibility and protein repellency, which can minimize inflammatory responses. Based on these characteristics, PEG-based hydrogels have been successfully used in a range of tissue engineering and cell delivery applications.

The chemical structure of PEG and its derivatives plays an important role in regulating the hydrophilicity, biodegradability, mechanical properties, bioreactivity, and protein repellency of PEG-based micelles, films, and hydrogels. The common structural modification of PEG is attached to biodegradable poly(lactic acid) (PLA), poly(propylene oxide) (PPO), and poly(lactide-co-glycolide) (PLGA). Additionally, changing the chain arrangement of PEG from linear chains to more complex geometries (3-arm, 4-arm, Y-shaped, comb-like and dendritic-like) will also have a significant impact on gel properties. For example, the star-shaped or branched arrangement of PEG chains enables the formation of higher modulus and chemically tunable PEG hydrogels, which are beneficial to promote desirable cellular responses.

The degradability, injectability, and mechanical properties of PEG copolymers have expanded their applications in bone tissue engineering, polymer scaffolds, growth factor encapsulation, drug delivery, and cell delivery. PEG is also non-immunogenic and resistant to protein adsorption, making it suitable for in vivo and in vitro studies. BOC Sciences is equipped with state-of-the-art instruments to provide high-quality custom PEG synthesis. With our extensive experience, our team can carry out various PEG-based solutions, such as PEG-based drug delivery, PEG-based drug preparation, PEG-based vaccine development, and PEG-based genomics delivery.
