‘Fountain of Youth’ for Stem Cells?

ScienceDaily (Dec. 29, 2009) — Researchers from the University of Hong Kong and the Massachusetts Institute of Technology have published a study in the current issue of Cell Transplantation that explores ways to successfully keep stem cells “forever young” during implantation by slowing their growth, differentiation and proliferation.

“The successful storage and implantation of stem cells poses significant challenges for tissue engineering in the nervous system, challenges in addition to those inherent to neural regeneration,” said Dr. Ellis-Behnke, corresponding author. “There is a need for creating an environment that can regulate cell activity by delaying cell proliferation, proliferation and maturation. Nanoscaffolds can play a central role in organ regeneration as they act as templates and guides for cell proliferation, differentiation and tissue growth. It is also important to protect these fragile cells from the harsh environment in which they are transplanted.”

According to Dr. Ellis-Behnke, advancements in nanotechnology offer a “new era” in tissue and organ reconstruction. Thus, finding the right nano-sized scaffold could be beneficial, so the research team developed a “self-assembling nanofiber scaffold” (SAPNS), a nanotechnology application to use for implanting young cells…
