Methods for using the obese product to stimulate hematopoietic development

   
   

The present invention relates to methods for using various forms of a novel receptor expressed by hematopoietic and endothelial cells. An additional variant form of this receptor has been detected in brain cells and shown to bind to the obese gene product, leptin. Therefore, leptin may be used to stimulate the growth and development of receptor-positive hematopoietic and endothelial cells in vitro and in vivo. In addition, this receptor is selectively expressed in hematopoietic progenitor cells with long-term repopulating potential. Thus, agents that specifically bind to this receptor may be used to identify and isolate progenitor cells for a variety of clinical applications.

La actual invención se relaciona con los métodos para usar varias formas de un receptor de la novela expresado por las células hematopoietic y endothelial. Una forma variable adicional de este receptor se ha detectado en células de cerebro y se ha demostrado al lazo al producto obeso del gene, leptin. Por lo tanto, el leptin se puede utilizar para estimular el crecimiento y el desarrollo de células hematopoietic y endothelial receptor-positivas in vitro e in vivo. Además, este receptor se expresa selectivamente en células hematopoietic del progenitor con potencial repopulating a largo plazo. Así, los agentes que atan específicamente a este receptor se pueden utilizar para identificar y para aislar las células del progenitor para una variedad de usos clínicos.
