Neuroregenerative strategies in the brain: emerging significance of bonemorphogenetic protein 7 (BMP7)

Every year thousands of people suffer from brain injuries and stroke, anddevelop motor, sensory, and cognitive problems as a result of neuronal loss in thebrain. Unfortunately, the damaged brain has a limited ability to enact repair andcurrent modes of treatment are not sufficient to offset the damage. An extensivelist of growth factors, neurotrophic factors, cytokines, and drugs has been exploredas potential therapies. However, only a limited number of them may actually have thepotential to effectively offset the brain injury or stroke-related problems. One ofthe treatments considered for future brain repair is bone morphogenetic protein 7(BMP7), a factor currently used in patients to treat non-neurological diseases. The clinical application of BMP7 is based on its neuroprotective role in stroke animal models. This paper reviews the current approac hes considered for brain repair and discusses the novel convergent strategies by which BMP7 potentially can induce neuroregenerationNRC publication: Ye

Development of BMP7-producing human cells, using a third generation lentiviral gene delivery system

Bone morphogenetic protein 7 (BMP7), a member of the transforming growth factor \u3b2 (TGF-\u3b2) superfamily, plays important roles in the development of various tissues and organs in mouse and human. In particular, BMP7 is critical for the formation of the nervous system and it is considered to have therapeutic potential in brain injury and stroke. One approach to make BMP7 more suitable for therapeutic purposes is the development of efficient vectors that allow the consistent, reliable and cost-effective production of the BMP7 protein. In this study, we developed an efficient BMP7deliverysystem, using athirdgenerationlentiviral vector to produce functional BMP7 protein. The lentiviral transduction of several humancell types, including human embryonic kidney 293 (HEK293) cells, amniotic fluid cells, NTera2 neurons (NT2-N) and primary neuronal cultures resulted in BMP7 expression. The production of BMP7 protein was achieved for at least 4 weeks post-transduction, as determined by enzyme-linked immunosorbent assay (ELISA). SMAD phosphorylation and neuronal differentiation assays verified the bioactivity and functionality of the lentiviral-based BMP7 protein, respectively. In addition, the intracerebroventricular injection of the lentivirus resulted in exogenous BMP7 expression in both neurons and astrocytes in the mouse brain. Taken together, this genedeliverysystem provides a reliable source of functional BMP7 protein for future in vitro and in vivo studies.Peer reviewed: YesNRC publication: Ye
