Nanoscale scaffolds spur stem cells to cartilage repair

A spun 3-D scaffold of nanofibers did a better job of producing larger quantities of and a more durable type of the cartilage protein than flat, 2-D sheets of fibers did.

Johns Hopkins tissue engineers have used tiny, artificial fiber scaffolds thousands of times smaller than a human hair to help coax stem cells into developing into cartilage, the shock-absorbing lining of elbows and knees that often wears thin from injury or age.

Reporting online June 4 in the Proceedings of the National Academy of Sciences, investigators say they have produced an important component of cartilage in both laboratory

Repair cartilage using stem cells

The study Sun has been working on in Dr. Farshid Guilak’s laboratory has found that engineered cartilage constructed from a particular type of stem cell integrate well with host cartilage, but not necessarily in a uniform way.

Sun was one of about thirty biomedical engineering students who presented at the department’s graduation with distinction reception on April 26. Other students have been working on exciting projects in optic imaging of tumors, synthetic biology, and deep brain stimulation, among other topics.

Sun’s project focused on how induced pluripotent stem cells can be used to study cartilage regeneration and repair.

SPAIN – Bone and Liver Transplants Soon Using Italian Technique. Authorization to Make Stem Cells Requested

Pier Paolo Parnigotto with Mariateresa Conconi

After a trachea transplant that was not rejected, performed in Barcelona by Italian surgeon Paolo Macchiarini, soon other organs and biotech tissues will be reconstructed in the lab thanks to a technique developed by the University of Padova. Bones, livers, the esophagus, pancreases, and muscles will be next, in research that will possibly take place in the Veneto. According to Pierpaolo Parnigotto, 61 year old professor of anatomy, who together with Maria Teresa Conconi carried out tissue engineering research for 15 years in the development of biotech organ grafts that

Artificial skin created using stem cells

In a first, scientists have grown artificial skin using stem cells derived from the umbilical cord.

Scientists from the Tissue Engineering Research Group at the Department of Histology at the University of Granada demonstrated the ability of Wharton jelly mesenschymal stem cells to turn to oral-mucosa or skin-regeneration epithelia.

Journal STEM CELLS Awards Pioneering Research into Limbal Stem Cell Deficiency

A young scientist who led research into the use of stem cells from hair follicles to treat the ocular surface disease has been named the winner of the Young Investigator Award by the journal STEM CELLS.

Dr. Ewa Meyer-Blazejewska will be presented with her award at The Stem Cell Symposium, hosted by the University of Kragujevac in Serbia on October 15, 2011. The $10,000 prize is awarded annually to a young scientist whose paper has been judged to be of worldwide significance by a global
