41. Relaxin binding to endothelial B receptor on endothelial cells also induces vasodilation. 42. Researchers extracted adult stem cells known as endothelial precursors from human bone marrow. 43. Endothelial cells line veins, arteries and lymph tissue.44. Endothelial cells are cells that line internal cavities including blood vessels and glands.45. Sinusoids display a discontinuous, fenestrated endothelial cell lining. 46. Endothelial cells, which have large fenestrae, are not covered by diaphragms.47. The lamina rara interna is adjacent to endothelial cells. 48. Endothelial cells accomplish these feats by using depolarization to alter their structural strength.49. Endothelial cells form a single, continuous layer that lines all vascular segments.50. Endothelial cell loss may be aggravated or accelerated by intraocular trauma or surgery.
