Patents Assigned to Cell Therapeutics, Inc.
  • Patent number: 7884072
    Abstract: The present invention provides a method of increasing neural stem cell numbers or neurogenesis by using prolactin. The method can be practiced in vivo to obtain more neural stem cells in situ, which can in turn produce more neurons or glial cells to compensate for lost or dysfunctional neural cells. The method can also be practiced in vitro to produce a large number of neural stem cells in culture. The cultured stem cells can be used, for example, for transplantation treatment of patients or animals suffering from neurodegenerative diseases or conditions. In addition, since neural stem cells are a source for olfactory neurons, the present invention also provides methods of increasing olfactory neurons and enhancing olfactory functions.

  • Publication number: 20090298762
    Abstract: Disclosed are biologically active protein conjugates that comprise a biologically active polypeptide coupled via a peptide bond to a polypeptide comprising from 2 to about 500 units of a repeating peptide motif, wherein the biologically active protein conjugate exhibits a modified plasma half-life compared to the intrinsic half-life of the unconjugated biologically active polypeptide or protein. Also disclosed are methods of making and using the conjugated proteins, as well as methods for determining whether a given conjugate exhibits a modified half life relative to the intrinsic half life of the unconjugated polypeptide.
