Bone morphogenic protein-2 (BMP-2) loaded nanoparticles mixed with human mesenchymal stem cell in fibrin hydrogel for bone tissue engineering
Abstract
Recent tissue engineering efforts have been focused on the use of natural or synthetic matrices which combine the characteristics of biodegradable properties with those of protein delivery vehicles, allowing for implanted cell actions and enhanced tissue regeneration. The principal objective of this study was to assess the feasibility of ectopic bone formation in a three-dimensional fibrin construct mixed with bone morphogenic protein-2 (BMP-2) loaded in nano-carriers for the osteogenic differentiation of human mesenchymal stem cells (hMSCs). The results of our evaluation showed that the osteogenic differentiation of hMSCs embedded in the fibrin construct was affected significantly by the stimulation of growth factors loaded in nanoparticles. When the osteoinduction activity of hMSCs in fibrin construct was evaluated in an in vitro test followed by RT-PCR, real time-QPCR, Western blotting, histological and immunohistochemical examinations, significant homogeneous bone formation was observed histologically throughout the fibrin construct containing the growth factor (BMP-2) loaded into the nanoparticles. With the above detection techniques, the BMP-2-loaded nanoparticles encapsulated in fibrin constructs evidenced more potent ef...Continue Reading

Antifungals (ASM)
An antifungal, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis, cryptococcal meningitis, and others. Discover the latest research on antifungals here.
Adult Stem Cells
Adult stem cells reside in unique niches that provide vital cues for their survival, self-renewal, and differentiation. They hold great promise for use in tissue repair and regeneration as a novel therapeutic strategies. Here is the latest research.
Allogenic & Autologous Therapies
Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
