One of the endogenous transformation products of tetrahydrocannabinol (THC) is THC-11-oic acid, and ajulemic acid (AJA; dimethylheptyl-THC-11-oic acid) is a side-chain synthetic analog of THC-11-oic acid. In preclinical studies, AJA has been found to be a potent anti-inflammatory agent without psychoactive properties. Based on recent reports suggesting(More)
OBJECTIVE Much remains to be learned about the intimate relationship between bone marrow and its surrounding tissue: the bone. We hypothesized that bone marrow accessory cell populations might regulate the development of human bone precursor cells. MATERIALS AND METHODS We used immunologic phenotyping, and isolation methods to fractionate subpopulations(More)
Little is known concerning the interaction of thrombopoietin (TPO) with other megakaryocyte-active cytokines in directing the early events of megakaryocyte development. Culture of CD34(+) cells in interleukins (IL) -1, -6, -11, plus stem cell factor (SCF; S) results in a 10- to 12-fold expansion in total cell numbers, whereas total CD41(+) megakaryocytes(More)
The ability to isolate functional populations of hematopoietic progenitor cells is important to the process of hematopoietic cell transplantation and to the understanding of hematopoietic cell biology in health and disease. We show that a subpopulation of human bone marrow hematopoietic cells bearing the pan-hematopoietic antigen CD34 also binds(More)
