8 hours ago Now you see it, now you don't: the epigenetic mark, 5-hydroxymethylcytosine (5hmC), does a disappearing act in culture.Mouse skin cells before and after cell culture show major loss of 5hmC, one of the many rapid molecular changes observed in cell cultures, reported by Nestor and colleagues in Genome Biology. Images depict the loss of red immunostaining for 5hmC in nuclei from cells grown in culture, but not green immunofluorescence (5-methylcytosine) and blue DAPI staining (DNA). Scale bar5 microns. Credit: S. Pennings lab. Cell cultures used in biology and medical research may not act as a faithful mimic of real tissue, according to research published in Genome Biology. The study finds that laboratory-grown cells experience altered cell states within three days as they adapt to their new environment. Studies of human disease, including cancer, rely on the use of cell cultures that have often been grown for decades. The findings could therefore affect the interpretation of past studies and provide important clues for improving cell cultures in the future. Scientists typically use models to study the basics of human biology. The most common model system is cultured cells, which are taken from the body and coaxed into growing … Continue reading →

Ras Al Khaimah, UAE (PRWEB) February 04, 2015 Grace Centurys portfolio firm, Provia Laboratories, LLC, is pleased to announce the provisional approval of Provia Laboratories Bahamas Ltd., Provia s sister entity, to conduct stem cell storage and research.
