Transplantation of mesenchymal stem cells embedded in Atelocollagen gel to the intervertebral disc: a potential therapeutic model for disc degeneration.

150 150 NZ Stem Cell Treatment Centre

Biomaterials. 2003 Sep;24(20):3531-41 Authors: Sakai D, Mochida J, Yamamoto Y, Nomura T, Okuma M, Nishimura K, Nakai T, Ando K, Hotta T Intervertebral disc degeneration is considered to be one of the major causes of low back pain. Despite this irreversible phenomenon, attempts to decelerate disc degeneration using various techniques have been reported. However, to…

Biologic strategies for the therapy of intervertebral disc degeneration.

150 150 NZ Stem Cell Treatment Centre

Expert Opin Biol Ther. 2003 Dec;3(8):1209-14 Authors: Gruber HE, Hanley EN Recent advances in tissue engineering have led to promising new approaches for the biologic treatment of disc degeneration. At present, there is no effective therapy for disc degeneration, a condition which results in large healthcare and socio-economic costs. This article will examine the current…

Light-activated gene transduction of recombinant adeno-associated virus in human mesenchymal stem cells.

150 150 NZ Stem Cell Treatment Centre

Gene Ther. 2004 Jan;11(1):34-41 Authors: Ito H, Goater JJ, Tiyapatanaputi P, Rubery PT, O’Keefe RJ, Schwarz EM Deficiencies in skeletal tissue repair and regeneration lead to conditions like osteoarthritis, osteoporosis and degenerative disc disease. While no cure for these conditions is available, the use of human bone marrow derived-mesenchymal stem cells (HuMSCs) has been shown…

Cell therapy for disc degeneration–potentials and pitfalls.

150 150 NZ Stem Cell Treatment Centre

Orthop Clin North Am. 2004 Jan;35(1):85-93 Authors: Brisby H, Tao H, Ma DD, Diwan AD Disc degeneration is considered a major source of pain in patients with chronic low back pain. Novel strategies to cure or decrease the symptoms and increase the patient’s quality of life and function are under development. Until recently conservative treatment…

Stem cell regeneration of the nucleus pulposus.

150 150 NZ Stem Cell Treatment Centre

Spine J. 2004 Nov-Dec;4(6 Suppl):348S-353S Authors: Risbud MV, Shapiro IM, Vaccaro AR, Albert TJ Low back pain due to disc degeneration is one of the largest health problems faced in this nation when judged by lost work time and direct as well as indirect costs. Many experimental methods are being explored to treat or to…

Bone mesenchymal stem cells transplanted into rabbit intervertebral discs can increase proteoglycans.

150 150 NZ Stem Cell Treatment Centre

Clin Orthop Relat Res. 2005 Jan;(430):219-26 Authors: Zhang YG, Guo X, Xu P, Kang LL, Li J We sought to determine whether transplanted allogeneic bone mesenchymal stem cells can survive and increase the amount of proteoglycans in intervertebral discs. We used the rabbit intervertebral disc as a model, creating three groups: an uninjected control group,…

New strategies for disc repair: novel preclinical trials.

150 150 NZ Stem Cell Treatment Centre

J Orthop Sci. 2005;10(1):112-8 Authors: Mochida J Degeneration of lumbar intervertebral discs is a major cause of low back complaints, an irreversible occurrence with no currently available treatment. Furthermore, various surgical procedures can accelerate disc degeneration. On the other hand, recent experimental studies on disc cells have demonstrated an important role for the nucleus pulposus…

Regenerative effects of transplanting mesenchymal stem cells embedded in atelocollagen to the degenerated intervertebral disc.

150 150 NZ Stem Cell Treatment Centre

Biomaterials. 2006 Jan;27(3):335-45 Authors: Sakai D, Mochida J, Iwashina T, Hiyama A, Omi H, Imai M, Nakai T, Ando K, Hotta T Intervertebral disc (IVD) degeneration, a common cause of low back pain in humans, is a relentlessly progressive phenomenon with no currently available effective treatment. In an attempt to solve this dilemma, we transplanted…
