Human Trophoblast Progenitor Cells Express and Release Angiogenic Factors

Trophoblast stem cells develop from polar trophoectoderm and give rise to the cells that generate the placenta. Trophoblast cells are responsible for the uterinal invasion and vascular remodeling during the implantation of the embryo. However this knowledge is not yet to be confirmed for trophoblast progenitor cells (TPCs). In this study, we aimed to demonstrate that human TPCs (hTPCs) express ...

C 3 and C 5 Human Skin Mast Cells

IgE-mediated anaphylactic degranulation of isolated human skin mast cells.

Isolated human skin mast cells (HSMC) were prepared and cultured overnight before functional and electron microscopic studies. Mast cell suspensions were examined after stimulation with anti-IgE to produce anaphylactic degranulation or examined in buffer-incubated controls. Histamine release was measured in replicate samples. Control, isolated HSMC studied by electron microscopy were well prese...

Mast cells in leprosy skin lesions.

The density and distribution of mast cells was assessed in skin biopsies of 118 untreated leprosy cases and 20 healthy individuals taken as controls. Mast cells were present in only small numbers in the skin biopsies of healthy individuals. Significantly higher mast cell counts were obtained in the skin lesions of indeterminate leprosy (P < 0.01). The mast cell count in the tuberculoid group wa...
