  • Patent number: 5972886
    Abstract: A novel megakaryocyte differentiation factor, for example, consisting essentially of SEQ ID NO: 30; DNA coding for the megakaryocyte differentiation factor, an expression vector comprising the DNA, a host transformed with the expression vector, and a process for production of the megakaryocyte differentiation factor using the host.The megakaryocyte differentiation factor accelerates differentiation of megakaryocytes in the presence of IL-3, and acts as a thrombopoietin, and therefore an effective medicament to various diseases involving a decrease in platelete.

  • Patent number: 5831030
    Abstract: The present invention provides novel megakaryocyte differentiation factors, which are useful as therapeutic agents due to their accelerating effects on the differentiation of megakaryocytes and their thrombopoietic effects. The megakaryocyte differentiation factors of the present invention include the megakaryocyte differentiation factor having the amino acid sequence shown in SEQ ID NO: 34. The present invention also provides DNA coding for the megakaryocyte differentiation factors of the present invention, expression vectors containing the DNA, hosts transformed with the expression vectors, and processes for production of the megakaryocyte differentiation factors using transformed hosts. The present invention further provides specific antibodies to the megakaryocyte differentiation factors of the present invention.
