  • Patent number: 10570207
    Abstract: Disclosed herein are non-myeloablative antibody-toxin conjugates and compositions that target cell surface markers, such as the CD34, CD45 or CD117 receptors, and related methods of their use to effectively conditioning a subject's tissues (e.g., bone marrow tissue) prior to engraftment or transplant. The compositions and methods disclosed herein may be used to condition a subject's tissues in advance of, for example, hematopoietic stem cell transplant and advantageously such compositions and methods do not cause the toxicities that are commonly associated with traditional conditioning methods.

  • Patent number: 8461127
    Abstract: The expansion of a population of stem cells or progenitor cells, or precursors thereof, may be accomplished by disrupting or inhibiting p21cip1/waf1 and/or p27, cyclin dependent kinase inhibitors. In the absence of p27 activity, progenitor cells move into the cell cycle and proliferate; whereas in the absence of p21 activity, stem cells move into the cell cycle and proliferate without losing their pluripotentiality (i.e., their ability to differentiate into the various cell lines found in the blood stream). Any type of stem cell or progenitor cell, or precursor thereof, including, but not limited to, hematopoietic, gastrointestinal, lung, neural, skin, muscle, cardiac muscle, renal, mesenchymal, embryonic, fetal, or liver cell may be used in accordance with the invention.
