Thymic
nurse cells - Ia-bearing epithelium involved in T-lymphocyte differentiation?
These jumping genes then use
nurse cells to produce invasive material (copies of themselves called virus-like particles) that move into a nearby egg and then mobilize into the egg's DNA.
Thymic
nurse cells provide microenvi-ronment for secondary T cell receptor a rearrangement in cortical thymocytes.
javanus vitellarium,
nurse cells were disposed at the top of the oocyte, all being surrounded by a sheath composed of follicular cells (Figure 4(b)).
VEGF is mainly expressed in placental syncytiotrophoblast and invasive chorionic trophoblast cells during pregnancy especially at the vascular bud site at early pregnancy during which syncytiotrophoblast cells were strongly positive.20The decrease in VEGF level in the peripheral blood of PIH patients suggests that VEGF affects the differentiation and proliferation of
nurse cells causes invasive functional disorder of
nurse cells and affects the physiological changes of spiral arterioles.
In polytrophic meroistic ovaries, such as the ovary of bees, each ovarian follicle is constituted by one or several
nurse cells that accompany the oocytes in the vitellarium.
