Cell morphologies, immuno-fluorescence staining, cell proliferation by lactate dehydrogenase assay and cell differentiation by alkaline phosphatase assay were utilized to assess the biocompatibility of the modified PLLA using osteoblast cell line MG63.

Layers of electrospun poly (l-lactide) fiber mesh coated with a poly (lactide-co-ethylene oxide fumarate) (PLEOF) hydrogel precursor solution were stacked and pressed together, and crosslinked to produce a laminated fiber-reinforced composite.
At days 14 and 21, alkaline phosphatase (ALPase) activity of the laminates was significantly higher than those of the fiber mesh and hydrogel.

In this study, block copolymers of poly (L-lactic acid) and poly (ethyl ethylene phosphate) (PLLA-b-PEEP) were synthesized and used to modify the PLLA surface via a spin-coating process, to understand whether surface modification with polyphosphoester-based polymer will be osteoinductive for potential bone tissue engineering applications.
Moreover, cellular alkaline phosphatase activity and mineral calcium depositions were also promoted by PEEP modification.

In this work, we successfully used an ultraviolet light initiated "graft from" polymerization method to fabricate polymer functionalized carbon nanotubes (PFCNTs) with pendant chains of various functionalities, including poly (ethylene glycol) chains to boost dispersibility and pendant epoxy groups for protein conjugate sites.
A model enzyme, alkaline phosphatase, was used to study biomolecule loading efficiency as well as the retention of enzyme activity.

20158316 Wang G, Kucharski C, Lin X, Uludag H: Bisphosphonate-coated BSA nanoparticles lack bone targeting after systemic administration. J Drug Target. 2010 Feb 16.

A polymeric conjugate of polyethyleneimine-graft-poly (ethylene glycol) and 2-(3-mercaptopropylsulfanyl)-ethyl-1,1-bisphosphonic acid (PEI-PEG-thiolBP) was prepared and used for surface coating of bovine serum albumin (BSA) nanoparticles (NPs) designed for bone-specific delivery of bone morphogenetic protein-2 (BMP-2).
On the basis of an alkaline phosphatase (ALP) induction assay, the NP-encapsulated BMP-2 displayed full retention of its bioactivity, except for BMP-2 in PEI-coated NPs.

In particular, we have proposed a tissue engineering approach for orbital bone repair based on a cyclic acetal biomaterial formed from 5-ethyl-5-(hydroxymethyl)-beta,beta-dimethyl-1,3-dioxane-2-ethanol diacrylate (EHD) and poly (ethylene glycol) diacrylate (PEGDA).
This upregulation of BMP-2 expression is associated by a more rapid hMSC differentiation, as measured by alkaline phosphatase expression.

In this work, injectable, biodegradable hydrogel composites of crosslinked oligo (poly (ethylene glycol) fumarate) and gelatin microparticles (MPs) were used to fabricate a bilayered osteochondral construct.
In the osteogenic layer, cells maintained their alkaline phosphatase activity during the coculture; however, mineralization was delayed by the presence of TGF-beta3.

We show herein that Col-doped HAp/CTS biocomposite (i.e., HAp/Col/CTS) containing 27.8 wt% HAp nanoparticles, 7.2 wt% Col, and 57.8 wt% CTS can be successfully electrospun into nanofibrous form through using small amount (7.2 wt%) of ultrahigh-molecular-weight poly (ethylene oxide) as the fiber-forming additive.
In comparison with different controls, significant increments in osteoblast proliferation, alkaline phosphatase expression, and mineral deposition were observed.

We have cryopreserved cynomolgus and human ES cells by the vitrification method, using a chemically-defined dimethyl sulfoxide (Me (2) SO)-free and serum-free medium composed of Euro-Collins solution as a base medium and 40% (v/v) ethylene glycol (EG) and 10% (w/v) polyethylene glycol (PEG) as cryoprotectants.
After the cryopreservation and thawing cycle, hES cells were easily cultured and expressed undifferentiated cell markers such as Nanog, Oct-4, SSEA-4, and alkaline phosphatase activity after several subculturing steps.

20222105 Sung K, Kamiya N, Kawata N, Kamiya S, Goto M: Functional glass surface displaying a glutamyl donor substrate for transglutaminase-mediated protein immobilization. Biotechnol J. 2010 Mar 10.

Validation of the Z-QG modified glass surfaces with recombinant enhanced green fluorescent proteins revealed that the insertion of a di (ethylene glycol) linker between the terminal Z-QG moiety and the base not only enhances enzymatic protein immobilization efficiency but also decreases nonselective protein adsorption.
A bacterial alkaline phosphatase fused with a K-tag at the N terminus was also successfully immobilized to the designed glass surface, suggesting that the chemically modified glass surface displaying a spatially controlled glutamyl donor substrate is a potential platform for MTG-mediated fabrication of protein-based solid biomaterials.
