Bone regrowth using ceramic substitute and E. coli-derived growth factors


New Rochelle, NY, October 16, 2019-Synthetic bone substitutes are promising materials for bone defect repair, but their efficacy can be substantially improved by bioactive agents such as growth factors. In a new study, researchers have modified beta-tricalcium phosphate (β-TCP) with increasing quantities of bone morphogenetic protein 2 (BMP-2) derived from

E. coli

and shown improved bone healing. The study is published in

Tissue Engineering

, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

Yuelian Liu, PhD, Academic Center for Dentistry Amsterdam, Amsterdam, Netherlands, and colleagues present their work in an article titled ”

Dose Effects of Slow-Released Bone Morphogenetic Protein-2 Functionalized β-Tricalcium Phosphate in Repairing Critical-Sized Bone Defects

“.

The authors created bone defects in a rat calvarial model and then attempted repair using β-TCP granules coated with a biomimetic calcium phosphate preparation that allows slow release of BMP-2. Bone growth and maturation were studied in comparison with autologous bone grafts using micro-CT scans, histology, and histomorphometry, and toxicity was assessed with blood tests. The

E. coli

-derived BMP-2 successfully improved bone formation with efficacy comparable to autologous grafts, and higher BMP-2 concentration promoted bone maturation.

“The dosage effect of

E. coli

-derived BMP-2 on bone formation provides valuable information for researchers and commercial stakeholders interested in a more cost-effective BMP-2 source compared to traditional mammalian cell production,” says
