INS-1 and INS-2 New insulin-secreting cell lines (INS-1 and INS-2) were established from cells isolated from an x-ray-induced rat transplantable insulinoma. The continuous growth of these cells was found to be dependent on the reducing agent 2-mercaptoethanol. Removal of this thiol compound caused a 15-fold drop in total cellular glutathione levels. These cells proliferated slowly (population doubling time about 100 h) and, in general, showed morphological characteristics typical of native beta-cells. Most cells stained positive for insulin and did not react with antibodies against the other islet hormones. The content of immunoreactive insulin was about 8 micrograms/10(6) cells, corresponding to 20% of the native beta-cell content. These cells synthesized both proinsulin I and II and displayed conversion rates of the two precursor hormones similar to those observed in rat islets. However, glucose failed to stimulate the rate of proinsulin biosynthesis. In static incubations, glucose stimulated insulin secretion from floating cell clusters or from attached cells. Under perifusion conditions, 10 mM but not 1 mM glucose enhanced secretion 2.2-fold. In the presence of forskolin and 3-isobutyl-1-methylxanthine, increase of glucose concentration from 2.8-20 mM caused a 4-fold enhancement of the rate of secretion. Glucose also depolarized INS-1 cells and raised the concentration of cytosolic Ca2+. This suggests that glucose is still capable of eliciting part of the ionic events at the plasma membrane, which leads to insulin secretion. The structural and functional characteristics of INS-1 cells remained unchanged over a period of 2 yr (about 80 passages). Although INS-2 cells have not been fully characterized, their insulin content was similar to that of INS-1 cells and they also remain partially sensitive to glucose as a secretagogue. INS-1 cells retain beta-cell surface antigens, as revealed by reactivity with the antigangloside monoclonal antibodies R2D6 and A2B5. These findings indicate that INS-1 cells have remained stable and retain a high degree of differentiation which should make them a suitable model for studying various aspects of beta-cell function.

What are stem cells? Stem cells are the foundation cells for our bodies. The highly specialized cells that make up our organs and tissues originally came from an initial pool of stem cells that formed shortly after fertilization. Throughout our lives, we continue to rely on persisting stem cells to repair injured tissues and replace cells that are lost every day, such as those in our skin, hair, blood, and the lining of our gut. 8. What is a stem cell line? Stem cells can be broadly defined by two characteristics, sometimes referred to as the “cardinal properties of stem cells”: their capacity to self-renew (divide in a way that generates more stem cells) and to differentiate (to turn into mature, specialized cells that make up our tissues and organs). A stem cell line is a population of cells that can replicate themselves for long periods of time in vitro, meaning outside of the body. These cell lines are grown in incubators with specialized growth factorcontaining media (liquid food source), at a temperature and oxygen/carbon dioxide mixture that approximate the conditions inside the mammalian body. stem-cell-glossary http://www.isscr.org/home/resources/learn-about-stem-cells/stem-cell-glossary Cell line Cells that can be maintained and grown in culture and display an immortal or indefinite life span. Cell type A specific subset of cells within the body, defined by their appearance, location and function. i) adipocyte: the functional cell type of fat, or adipose tissue, that is found throughout the body, particularly under the skin. Adipocytes store and synthesize fat for energy, thermal regulation and cushioning against mechanical shock ii) cardiomyocytes: the functional muscle cell type of the heart that allows it to beat continuously and rhythmically iii) chondrocyte: the functional cell type that makes cartilage for joints, ear canals, trachea, epiglottis, larynx, the discs between vertebrae and the ends of ribs iv) fibroblast: a connective or support cell found within most tissues of the body. Fibroblasts provide an instructive support scaffold to help the functional cell types of a specific organ perform correctly. v) hepatocyte: the functional cell type of the liver that makes enzymes for detoxifying metabolic waste, destroying red blood cells and reclaiming their constituents, and the synthesis of proteins for the blood plasma vi) hematopoietic cell: the functional cell type that makes blood. Hematopoietic cells are found within the bone marrow of adults. In the fetus, hematopoietic cells are found within the liver, spleen, bone marrow and support tissues surrounding the fetus in the womb. vii) myocyte: the functional cell type of muscles viii) neuron: the functional cell type of the brain that is specialized in conducting impulses ix) osteoblast: the functional cell type responsible for making bone x) islet cell: the functional cell of the pancreas that is responsible for secreting insulin, glucogon, gastrin and somatostatin. Together, these molecules regulate a number of processes including carbohydrate and fat metabolism, blood glucose levels and acid secretions into the stomach. http://www.isscr.org/home/resources/learn-about-stem-cells/stem-cell-facts Stem cell basics http://stemcells.nih.gov/info/basics/pages/basics1.aspx
