New protein-based hydrogel can heal wounds

New protein-based hydrogel can heal wounds | Dental Implant and Bone Regeneration | Scoop.it
A team of bioengineers at Brigham and Women's Hospital (BWH), led by Dr. Ali Khademhosseini and Dr. Nasim Annabi of the Biomedical Engineering Division, have developed a protein-based, elastic gel that mimics the properties of skin and blood vessels when exposed to light and could therefore be used to heal wounds.
Alessandro Dentoni's insight:

The new material, known as a photocrosslinkable elastin-like polypeptide-based (ELP) hydrogel, offers several astounding benefits......

Engineering a Better Way to Rebuild Bone

Engineering a Better Way to Rebuild Bone | Dental Implant and Bone Regeneration | Scoop.it
Traumatic bone injuries are often so severe that the body can’t effectively repair the damage on its own. To aid the recovery, clinicians inject patients with proteins called growth factors. The treatment is costly, requiring large amounts of growth factors. The growth factors also disperse, creating unwanted bone formation. A new developing technology could provide more efficient delivery of the bone regenerating growth factors.
Alessandro Dentoni's insight:

The research team developed a method of fabricating pure heparin microparticles from a modified heparin methacrylamide species that can be thermally cross-linked to growth factors. The technology avoids the bulky materials currently used to deliver growth factors.

Plant-protein based nano-fiber scaffolds for Wound Healing

This technology facilitates creation of three-dimensional tissue scaffolds (TTS) that can either be seeded with specific cells with the intent to form a particular target tissue (for instance liver tissue, lung tissue or nerve tissue), or can be implanted without cell seeding into a target tissue: for instance, connective tissue defects that need to be filled (e.g. in lung diseases leading to the formation of large connective tissue defects,) or in other uses, where augmentation of target tissues are desired.

Can wood replace damaged bones?

Can wood replace damaged bones? | Dental Implant and Bone Regeneration | Scoop.it

Researchers from the National Research Council of Italy (CNR) writing in a forthcoming issue of the International Journal of Healthcare Technology and Management suggest that it can. It turns out that the structure of some woods at the microscopic level is very close to that of natural bone; both have unique biomechanical properties such as high strength and lightness

Utility of a Slightly Modified Collagen Scaffold « Kyoto University International Industry-Academia Collaboration HP | Dental Implant and Bone Regeneration | Scoop.it

The novel collagen fiber scaffold made in this way appears to be useful not only as a ''scaffold'' for tissue regeneration of wounds and surgical incisions but also as a so-called ''cell capsule'' to carry cells to a location.
