    • The present invention is based on the discovery that nitric oxide (NO) is an important growth regulator in an intact developing organism. In particular, the present invention relates to a method of increasing in a mammal a population of hematopoietic stem cells in bone marrow which are capable of undergoing normal hematopoiesis and differentiation, wherein the bone marrow is contacted with an inhibitor of NO, such as an inhibitor of nitric oxide synthase (NOS), thereby producing bone marrow having an increased population of hematopoietic stem cells which are capable of undergoing normal hematopoiesis and differentiation. The present invention also relates to a method of increasing a population of cells in S phase in a tissue of a mammal, comprising contacting the tissue with an inhibitor of NO, such as an inhibitor of NOS. The invention also pertains to a method of regenerating tissue in an adult mammal comprising contacting a selected tissue (e.g., blood, skin, bone and digestive epithelium), or precursor cells of the selected tissue, with an inhibitor of NO, thereby inhibiting differentiation and inducing proliferation of cells of the tissue.
    • 本发明基于一氧化氮(NO)是完整发育生物体中重要的生长调节剂的发现。 具体而言,本发明涉及在哺乳动物中增加骨髓中能够进行正常造血和分化的造血干细胞群的方法,其中骨髓与NO抑制剂例如抑制剂 的一氧化氮合酶(NOS),由此产生具有增加的造血干细胞群体的骨髓,所述造血干细胞群体能够经历正常的造血和分化。 本发明还涉及增加哺乳动物组织中S期细胞群的方法,包括使组织与NO抑制剂例如NOS抑制剂接触。 本发明还涉及在成年哺乳动物中再生组织的方法,其包括使选定组织(例如血液,皮肤,骨和消化上皮)或所选组织的前体细胞与NO抑制剂接触,由此抑制分化和 诱导组织细胞的增殖。
