Conclusive evidence on role of circulating mesenchymal stem cells in organ injury (9/2/2014)

Conclusive evidence on role of circulating mesenchymal stem cells in organ injuryMesenchymal stem cells are present in virtually every type of human tissue and may help in organ regeneration after injury. But the theory that MSCs are released from the bone marrow into the blood stream following organ damage, and migrate to the site of injury, has long been debated. ...> Full Article


Chemically extracted acellular allogeneic nerve graft with CNTF for sciatic nerve repair (9/1/2014)

Chemically extracted acellular allogeneic nerve, from which Schwann cells, myelin sheath and disintegrating fragments have been removed, reduced postoperative immune rejection. Simultaneously, chemically extracted acellular allogeneic nerve retains neural substrates and base materials, such as the bottom layer of Schwann cells, which can provide a good scaffold in the process of nerve regeneration. ...> Full Article


Researchers find that coronary arteries hold heart-regenerating cells (8/31/2014)

Endothelial cells residing in the coronary arteries can function as cardiac stem cells to produce new heart muscle tissue, Vanderbilt University investigators have discovered. ...> Full Article


How lizards regenerate their tails: researchers discover genetic 'recipe' (8/30/2014)

How lizards regenerate their tails: researchers discover genetic 'recipe'By understanding the secret of how lizards regenerate their tails, researchers may be able to develop ways to stimulate the regeneration of limbs in humans. Now, a team of researchers from Arizona State University is one step closer to solving that mystery. The scientists have discovered the genetic 'recipe' for lizard tail regeneration, which may come down to using genetic ingredients in just the right mixture and amounts. ...> Full Article

Stem cells reveal how illness-linked genetic variation affects neurons (8/28/2014)

Stem cells reveal how illness-linked genetic variation affects neuronsA genetic variation linked to schizophrenia, bipolar disorder and severe depression wreaks havoc on connections among neurons in the developing brain, a team of researchers reports. The study used stem cells generated from people with and without mental illness to observe the effects of a rare and pernicious genetic variation on young brain cells. The results add to evidence that several major mental illnesses have common roots in faulty 'wiring' during early brain development. ...> Full Article


New blood: Tracing the beginnings of hematopoietic stem cells (8/27/2014)

New blood: Tracing the beginnings of hematopoietic stem cellsIn a paper published online this week in Nature, researchers at the University of California, San Diego School of Medicine elaborate upon a crucial signaling pathway and the role of key proteins, which may help clear the way to generate HSCs from human pluripotent precursors, similar to advances with other kinds of tissue stem cells. ...> Full Article


Tissue development 'roadmap' created to guide stem cell medicine (8/27/2014)

In a boon to stem cell research and regenerative medicine, scientists at Boston Children's Hospital, the Wyss Institute for Biologically Inspired Engineering at Harvard University and Boston University have created a computer algorithm called CellNet as a 'roadmap' for cell and tissue engineering, to ensure that cells engineered in the lab have the same favorable properties as cells in our own bodies. ...> Full Article


Adipose-derived stem cells and nerve regeneration (8/27/2014)

Current clinical treatment of peripheral nerve injuries predominantly relies on sacrificing a section of nerve from elsewhere in the body to provide a graft at the injury site. Much work has been done to develop a bioengineered nerve graft, precluding sacrifice of a functional nerve. This prospect examines the potential of adipose-derived stem cells to improve nerve repair assisted by bioengineered nerve grafts. ...> Full Article


Dynamic culture of a thermosensitive collagen hydrogel improves tissue-engineered peripheral nerve (8/27/2014)

Dynamic culture of a thermosensitive collagen hydrogel improves tissue-engineered peripheral nerveIn a study reported on Neural Regeneration Research, a thermosensitive collagen hydrogel remained as a liquid when kept at temperatures below 10C and gelled when the temperature was increased to 37C in an incubator for 30 minutes, which was used as an extracellular matrix and combined with bone marrow mesenchymal stem cells to construct tissue-engineered peripheral nerve composites in vitro. ...> Full Article


Stem cells in the skeletal muscle promote the regeneration of severe nerve peripheral injury (8/26/2014)

Skeletal muscle derived-multipotent stem cells were transplanted for the peripheral nerve injury, having the irreversible long nerve gap, using acellular conduit bridging. Applied cells differentiated into all of axon support cells, and contributed to increased vascular formation, which is favorable for blood supply and waste product excretion, providing the sustained expression of neurotrophic and nerve/vascular growth factors. Then, over 94 percent of axonal regeneration was achieved during eight weeks, and this was more effective (about triple) than healthy nerve autograft. ...> Full Article


Stimuli-responsive drug delivery system prevents transplant rejection (8/26/2014)

Stimuli-responsive drug delivery system prevents transplant rejectionA global collaboration including researchers from Brigham and Women's Hospital; Institute for Stem Cell Biology and Regenerative Medicine in Bangalore, India; and University Hospital of Bern, Switzerland, have developed a way to deliver immunosupressant drugs locally and when prompted, with the use of a biomaterial that self-assembles into a hydrogel (jello-like) material. The novel system is able to deliver targeted, controlled release of medication where and when it is needed. ...> Full Article


Stem cell therapy for central nerve system injuries: Glial cells hold the key (8/25/2014)

Bioengineers: Matrix stiffness is an essential tool in stem cell differentiation (8/24/2014)

Bioengineers: Matrix stiffness is an essential tool in stem cell differentiationBioengineers at the University of California, San Diego have proven that the stiffness of the extracellular matrix used to culture stem cells really does matter. The research team, led by bioengineering professor Adam Engler, also found that a protein binding the stem cell to the hydrogel is not a factor in the differentiation of the stem cell as previously suggested. The protein layer is merely an adhesive, the team reported Aug. 10 in the advance online edition of the journal Nature Materials. ...> Full Article
