Stem cell therapies are the leading and most sensational topic in the world of scientific research. The excitement is due to the huge potential these cells have in curing human diseases. What are stem cells? They are undifferentiated cells in human body that are capable of differentiating into specialized cell types. Stem cells differentiate into different cell types during early...
Edinburgh, U.K. - Scientific researchers have grown a completely functional organ from laboratory-developed cells in a living animal for the very first time. Scientists transplanted a fully functional thymus -- an important organ that supplies the body with immunity cells. Left: Specialised thymus cells were developed from an entirely distinct cell type utilizing a laboratory technique called re-programming. Right: The...
Following more than four decades of intense research, scientists may be closer to deciphering the precise mechanisms at work in stem cell development and differentiation, a recent paper published in the Journal of Molecular Endocrinology reports. Stem cells control organ homeostasis, growth, and self-regulation. This is done by relying on a network of short-range, localized transcription factors (TFs). Transcription factors are a major effector of physiological changes and wield significant influence on stem cell behavior in many ways.
