The Flt3 gene encodes a tyrosine kinase receptor highly related to the Kit and Fms gene products. We have studied the expression of Flt3 by using in situ hybridization of mouse tissue sections. The results show that Flt3 RNAs are present in certain regions of lympho-hematopoietic organs, placenta and nervous system. Flt3 is expressed in the medullary area of fetal and newborn thymus, in the paracortical regions of lymph nodes and in the red pulp of spleen. In placenta, labyrinthine trophoblasts express Flt3. Finally, Flt3 RNAs are found in several regions of the brain and in cerebellar Purkinje cells. Western-blot analysis showed that the FLT3 protein is present in the tissues positive for Flt3 RNA expression. Our observations allow for a comparison with the distribution of the Kit gene and analysis of a possible redundancy between KIT and FLT3 receptors.
