Abstract

Bone marrow (BM) cells from BALB/c mice infected with mixed-sex Schistosoma mansoni cercariae were assessed for their capacity to form in vitro colony forming units of erythroid (CFU-e) and granulocyte/macrophage (CFU-c) cells. At four weeks after infection, substantial BM commitment to granulopoiesis was noted by an increase in CFU-c, with no changes in CFU-e. Elevated marrow granulopoietic activity, although to a lesser extent, was also observed five weeks after either male or female cercarial infection. Preferential differentiation of precursor cells into eosinophilic and/or neutrophilic lineages was observed at weeks four and six post bisexual cercarial infection. After eight weeks of mixed infection, there was a marked suppression of CFU-e formation as compared with uninfected or single sex cercariae-infected mice. These results demonstrate that S. mansoni infection appears to influence either the differentiation capacity or the levels of BM cells at the progenitor cell level, and that maturation of worms and/or oviposition may contribute to changes in the CFU-e and CFU-c cell differentiation.

Adult Stem Cells

Adult stem cells reside in unique niches that provide vital cues for their survival, self-renewal, and differentiation. They hold great promise for use in tissue repair and regeneration as a novel therapeutic strategies. Here is the latest research.

Anthelmintics (ASM)

Anthelmintics or antihelminthics are a group of antiparasitic drugs that expel parasitic worms (helminths) and other internal parasites from the body by either stunning or killing them and without causing significant damage to the host. Discover the latest research on anthelmintics here.
