Bone marrow cells can become functional gut lining cells
Researchers report the discovery that cells used in bone marrow transplantation can develop into new cells lining the gut, according to a study by Yale School of Medicine in the Proceedings of the National Academy of Sciences.
The study showed that bone marrow derived cells can differentiate into functional gastrointestinal epithelial cells after bone marrow transplantation. Research was from the laboratory of Diane Krause, M.D., professor of Laboratory Medicine and senior author of the study, in collaboration with Marie Egan, M.D., associate professor of pediatrics, respiratory medicine, and cellular and molecular physiology.
"We demonstrated that the cells were functional by showing that they express functional chloride channels (known as CFTR, or cystic fibrosis transmembrane conductance regulator) which are necessary for fluid balance in the gut," Krause said.
The researchers used mice that do not have this chloride channel. After bone marrow transplantation from donor mice that do have the chloride channel, recipient mice had some normal chloride channel activity.
Alhough this is exciting, the levels of donor derived gut cells are currently far too low to be used as a treatment for cystic fibrosis, an inherited disease in which the organs, especially those of the pancreas, lungs, and intestines, become clogged with thick mucus.
"We hope this finding will have implications for cystic fibrosis, but this is a first step and there are many, many more years of research to be done before we can determine this," said Krause.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
