376 results about "Homeostasis" patented technology

In biology, homeostasis is the state of steady internal physical and chemical conditions maintained by living systems. This dynamic state of equilibrium is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits (homeostatic range). Other variables include the pH of extracellular fluid, the concentrations of sodium, potassium and calcium ions, as well as that of the blood sugar level, and these need to be regulated despite changes in the environment, diet, or level of activity. Each of these variables is controlled by one or more regulators or homeostatic mechanisms, which together maintain life.

Methods and systems for converting precursor cells into intestinal tissues through directed differentiation

The generation of complex organ tissues from human embryonic and pluripotent stem cells (PSCs) remains a major challenge for translational studies. It is shown that PSCs can be directed to differentiate into intestinal tissue in vitro by modulating the combinatorial activities of several signaling pathways in a step-wise fashion, effectively recapitulating in vivo fetal intestinal development. The resulting intestinal “organoids” were three-dimensional structures consisting of a polarized, columnar epithelium surrounded by mesenchyme that included a smooth muscle-like layer. The epithelium was patterned into crypt-like SOX9-positive proliferative zones and villus-like structures with all of the major functional cell types of the intestine. The culture system is used to demonstrate that expression of NEUROG3, a pro-endocrine transcription factor mutated in enteric anendocrinosis is sufficient to promote differentiation towards the enteroendocrine cell lineage. In conclusion, PSC-derived human intestinal tissue should allow for unprecedented studies of human intestinal development, homeostasis and disease.
