16579687 Moioli EK, Hong L, Guardado J, Clark PA, Mao JJ: Sustained release of TGFbeta3 from PLGA microspheres and its effect on early osteogenic differentiation of human mesenchymal stem cells. Tissue Eng. 2006 Mar;12(3):537-46.

To compare sterilization modalities of microspheres, bFGF was encapsulated in 50:50 PLGA microspheres and subjected to ethylene oxide (EO) gas, radio-frequency glow discharge (RFGD), or ultraviolet (UV) light.
Alkaline phosphatase staining intensity was markedly reduced 1 week after exposing hMSC-derived osteogenic cells to TGFbeta3.

METHODS: Plasmids encoding either constitutive human secreted alkaline phosphatase or murine erythropoietin inducible via a Tet-on system were formulated with PE6400 and intramuscularly injected into the mouse tibial anterior muscle.

Int J Toxicol. 2008;27 Suppl 2:93-128.

Doses up to 0.5 mg/kg day (-1) for 2 years using rats produced yellow discoloration of the serum, high serum alkaline phosphatase activity, and elevated serum glutamicpyruvic transaminase and glutamic-oxalacetic transaminase activities.
The impurities of commercial grade Poloxamer 188, as an example, include low-molecular-weight substances (aldehydes and both formic and acetic acids), as well as 1,4-dioxane and residual ethylene oxide and propylene oxide.

19995620 Xu W, Ma J, Jabbari E: Material properties and osteogenic differentiation of marrow stromal cells on fiber-reinforced laminated hydrogel nanocomposites. Acta Biomater. 2009 Dec 6.

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.

Following processing methods were tested: autoclavation (AUT), low-temperature-plasma sterilisation of demineralised allografts (D-LTP), ethylene oxide sterilisation (EtO), fresh frozen bone (FFB), 80 degrees C-thermodisinfection (80 degrees C), gamma-irradiation (Gamma), chemical solvent disinfection (CSD), and Barrycidal-disinfection (BAR).
Tests to confirm the osteoblastic differentiation included histochemical alkaline phosphatase staining and RT-PCR for osteocalcin.

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.

In this study, we applied a biomimetic coating method to provide electrospun scaffolds from a block copolymer-poly (ethylene oxide terephthalate)-poly (buthylene terephthalate), with a calcium phosphate layer to improve their bioactivity in bone tissue engineering.

The alkaline phosphatase activity was significantly higher for the ethylene oxide sterilized PLCL sheet.
