what substance is stored in the nucleus? Abstract : Background: TNF (tumor necrosis factor) is a master proinflammatory cytokine of central importance in both Crohn's Disease and Ulcerative Colitis. Now that we have identified our desired clusters, we can move on to marker identification, which will allow us to verify the identity of certain clusters and help surmise the identity of any unknown clusters. The neuronal compartment alone contains billions of neurons, with a not yet fully characterized number of neuronal subtypes. To attempt to interpret the identity of each cluster, marker genes are found as those that are uniquely highly expressed in a cluster, compared to all the other clusters. However, subsequent studies defining the properties of hematopoietic progenitor populations have demonstrated that most NK cells are Propagation of human corneal endothelial cells: a novel dual media approach. Taken together, these findings reveal a potential temporal requirement for Arx in maintaining α-cell identity. 1. Smeringaiova I, Paaske Utheim T, Jirsova K. Stem Cell Res Ther.
