P-selectin is a protein that in humans is encoded by the SELP gene. P-selectin functions as a cell adhesion molecule (CAM) on the surfaces of activated endothelial cells, which line the inner surface of blood vessels, and activated platelets. In unactivated endothelial cells, it is stored in granules called Weibel-Palade bodies. In unactivated platelets P-selectin is stored in α-granules.
Compounds and methods for inhibiting selectin-mediated function
Compounds and methods are provided for modulating in vitro and in vivo processes mediated by selectin binding. More specifically, selectin modulators and their use are described, wherein the selectin modulators that modulate (e.g., inhibit or enhance) a selectin-mediated function comprise a class of compounds termed BASAs (Benzyl Amino Sulfonic Acids, which include a portion or analogue thereof) linked to a carbohydrate or glycomimetic.

Method and composition for preventing pain in sickle cell patients
InactiveUS20080112955A1Avoid painPrevent and reduce frequencyBiocideCell receptors/surface-antigens/surface-determinantsP-selectinPreventing pain
A method of preventing pain in a sickle cell patient is disclosed. The method includes orally administering to the patient, an amount of an active agent effective on oral administration to inhibit binding of the patient's sickle erythrocytes to P-selectin on the patient's vascular endothelium. The inhibition may be evidenced in a number of ways. The active agent administration inhibits the adhesion of sickle erythrocytes to vascular endothelium in the patient, thereby preventing patient pain associated with vascular occlusion. Also disclosed are compositions useful in practicing the method.

Hemangioblast progenitor cells
InactiveUS20040052771A1Reduce bleedingAvoid adjustmentBiocideArtificial cell constructsP-selectinProgenitor
The invention relates to isolated hemangioblast cells. Hematopoietic and endothelial cells are postulated to be derived from a common progenitor, hemangioblast. While hemangioblast has been isolated retrospectively during embryonic stem cell differentiation, it has not been isolated from embryos or from bone marrow. Prospectively stable clonal cell lines have been isolated from mammalian embryos, from embryonic stem cells and from mammalian bone marrow that can differentiate in vitro into tubular structures with both endothelial and hematopoietic markers such as CD34, CD31, Flk-1, TIE2, P-selectin, Sca-1, thy-1, CD45, and smooth muscle actin. Gene expression profiles in the undifferentiated and differentiated cells were consistent with endothelial and hematopoietic differentiation potential. Transplantation studies in isogenic or immunodeficient mice demonstrated that these cells were not tumorigenic. In an appropriate microenvironment, the cells incorporate into the vasculature and participate in hematopoiesis.
