Injectable bone fluid can deliver stem cells, protein drugs

A research team in the UK has developed an injectable bone material they say can be used to deliver stem cells and temperature-sensitive protein therapies. The low viscosity fluid relies on body heat alone to solidify, gently transforming it into porous bone material.

The science team from the University of Nottingham says that the material can be adjusted to adapt to different types of tissues and can steer various cell types and therapeutics to precise locations in the body.

"Regenerative medicine holds huge promise for patients because it opens opportunities to heal tissues that would never repair spontaneously," says Kevin Shakesheff, PhD, professor of advanced drug delivery and tissue engineering at the University of Nottingham, "A powerful concept in regenerative medicine is the use of a porous material that fills the space within the body and promotes blood vessel formation, stem cell engraftment, and ultimately the formation of functional tissue." 

Shakesheff will discuss the use of injectable bone for stem cell delivery on July 14 at the 37th Annual Meeting & Exposition of the Controlled Release Society in Portland.
