Sox-4 facilitates thymocyte differentiation

Regulates Early Thymocyte Differentiation Bone Morphogenetic Protein 2/4 Signaling

A threshold level of NFATc1 activity facilitates thymocyte differentiation and opposes notch-driven leukaemia development

NFATc1 plays a critical role in double-negative thymocyte survival and differentiation. However, the signals that regulate Nfatc1 expression are incompletely characterized. Here we show a developmental stage-specific differential expression pattern of Nfatc1 driven by the distal (P1) or proximal (P2) promoters in thymocytes. Whereas, preTCR-negative thymocytes exhibit only P2 promoter-derived N...

Interferon regulatory factor 4 regulates thymocyte differentiation by repressing Runx3 expression.

The transcription factor interferon regulatory factor 4 (IRF4) was originally found to be preferentially expressed in lymphoid cells and to be required for the function, differentiation, and homeostasis of both mature T and B lymphocytes. Recent studies have indicated that IRF4 is also involved in early B-cell development. However, the role of IRF4 in intrathymic T-cell development remains unkn...

Defects in Thymocyte Differentiation and Thymocyte- Stromal Interactions in the Trisomy 16 Mouse

We have examined fetal thymic development in the trisomy 16 (Ts16) mouse, which is considered to be a model for human trisomy 21, or Down Syndrome. The Ts16 thymus contains 10 to 20% of the number of lymphocytes found in a normal thymus at a comparable stage. Expression of thymocyte differentiation markers (Thy-1, CD5, CD8, CD4, CD3, and HSA) is severely affected in Ts16 fetuses aged 14-18 gest...

Pancreatic Differentiation of Sox 17 Knock-in Mouse Embryonic Stem Cells in Vitro

The way to overcome current limitations in the generation of glucose-responsive insulin-producing cells is selective enrichment of the number of definitive endoderm (DE) progenitor cells. Sox17 is the marker of mesendoderm and definitive endoderm. The aim of the present research was to study the potential of Sox17 knock-in CGR8 mouse embryonic stem (ES) cells to differentiate into insulin produ...
