immature dendritic epithelial T cell precursor 2010-10-07T01:58:00Z immature DEC precursor NOTE: currently variable immune gene segments are not represented in the OBO Foundry. Cross-product definitions were not made as a result. Also, there are three different nomenclatures for the variable gamma segments. A double negative thymocyte that has a T cell receptor consisting of a gamma chain that has as part a Vgamma3 segment, and a delta chain. This cell type is CD4-negative, CD8-negative and CD24-positive. This cell-type is found in the fetal thymus with highest numbers occurring at E17-E18. immature DETC precursor fetal thymocyte
