develops from develops from immature dendritic epithelial T cell precursor mature dendritic epithelial T cell precursor 2010-10-07T02:05:46Z mature DEC precursor A 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-negative. This cell-type is found in the fetal thymus with highest numbers occurring at E17-E18. mature DETC 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. fetal thymocyte
